& Intro:
This is not the definitive guide to installing the TRD SPORTIVO SUSPENSION
KIT. This is simply a quick write up of the experience I went through when I
installed mine. I hope it helps anyone else that may have questions, but by no
means is this, the 100% official way to install the kit. So if you make a
mistake or mess up please DO NOT
BLAME ME. If any one catches something I have done wrong, PLEASE let me know. As
some of you know TRD and English instructions for the most part do not mix. The
only English instructions I received were for the installation of the member
spacers. There were no torque specs and pictures that would have helped me in
any way. Luckily there is www.spyderchat.com,
and some friends I know that have done this type of thing before. I was able to
ask questions, and bounce scenarios off of them. If you search on spyderchat,
you will be able to find all of the torque specs, or you can be lazy like me and
ask a good friend to send them. Not to worry though I have included them in this
article. (You know who you are, and thanks once again).
For anyone who is curious I am not a mechanic, but I have and do work on
cars. However I have never worked on suspension components before, so this was a
first for me. Mostly I have worked on motors, but I did not find this to be a
difficult installation. IMHO anyone who knows how to use basic tools (wrenches,
ratchets, jacks…) should be able to do this.
Please note that you WILL need to get an alignment done after the
install! I went to Toyota to have this done. The total cost for the 4-wheel
alignment was $105.22 including a 4-wheel balance. Over all it was painless. If
you plan on doing this keep at least 1 whole day clear on your calendar. I
started at 11:30am and was cleaned up and ready to eat at 7:30PM. I did not
break for lunch, and pretty much worked on the car during that entire time.

Front Strut and Swaybar Assembly
Rear Strut and Swaybar Assembly
Part
I Front strut Components Removal & Installation:
Ok, here we go.
A.
The first thing I did was to loosen the lug nuts on both front wheels.
B.
Next I removed the center cap over the strut tower using the standard
screwdriver. (please note I have previously installed the TRD Front Strut tower
brace, so it does look a little different than a stock car)
C.
Then I followed the advice
of an old friend whom had helped me countless times in the past while we
tinkered on our 240Zs. He explained to me the trouble he had gone through while
doing a similar install to his Z when it came to dismantling the strut assemble.
He had a bear of a time getting the center strut nut off once the struts
assemble was out of the car. This involved using vise grips (something I always
try to avoid). So I am not sure if this applied here, but I did not have the
trouble he did. Basically loosen the center strut nut prior to removing the
assembly from the car.
D.
After these task were completed I proceed to lift the car. I wanted as
much room as possible, and did not feel comfortable having the car resting on 4
jack stands (besides I only have 2) so I backed the rear up onto my ramps, and
lifted one side at a time from the marked lift points using my floor jack. I did
not use the center lift points for fear of not being able to get the jack out
from under the car once I was done. I do not know the exact height I had the car
at, but the jack stands were up to the forth notch, and I would guess at 12+
inches.
E.
Next I removed both the passenger and driver side wheels, and snapped
lots of pics for reference. Here
are some shots of the notes:
F.
Now that I had reference shots I proceed to dismantle things. First I
disconnected the sway bar form the upper portion of the link. It looked like it
would get in the way so I started here first.
G.
Then I removed the link from the lower suspension arm, and placed the
entire assembly in a zip lock baggie. Please note that there is NO washer for
the link where it mounts to the upper side of the lower suspension arm. The
bottom side however does have washers. BTW I removed the links from both sides
at this time.
H.
I then removed anything else that looked like it would get in the way.
First was the ABS speed sensor wire harness.
I.
Then the Brake line Mount.
J.
Now came the fun part, removing the steering knuckle from the strut.
I did not want to
create any unnecessary stress on the brake line, and the ABS speed sensor, so I
supported the calipers using my jack. This worked, but I just did not feel like
it was as stable, as I would have liked for it to be. So I switched over to the
jack case which was just the right height. (Sorry no picture of that)
K.
I then proceed to what I found to be the most difficult part. Removing
the front sway bar. First I removed the brackets on both sides (easy).
L. Getting the sway bar out was a royal pain in the ass. I did not even
think about taking pictures. In retrospect, I think it would of saved a lot of
time and effort if I had removed the front spare tire, and compartment. This I
believe would allow for a lot more room to maneuver the sway bar out with.
[Editors note: I
found removing the front spare tub almost a necessity.] Funny
thing is once I found the proper pattern, lift here turn there, inch this way,
it came out smoothly and the new one went back in easily.
M.
Now that I had no obstructions in the way or at least very few, I then
removed the top three nuts from the front strut tower brace/chassis mount. When
doing this be sure to hold up the strut assembly when removing the last nut. The
strut assemble might drop, and/or lean to one side. This however unlikely could
cause damage to the bolt that the nut mounts to. The following picture shows the
complete strut & spring assemble.
N.
Now it was time to use those spring compressors. I placed one compressor
on each side of the spring. Next I tightened them down by hand until I could not
turn them any more. Then I installed and tightened the safety locks. Once I felt
that every thing was secure I began to slowly remove the strut center nut.
Even with the spring
compressors in place, when the nut came off there was still some tension, just
enough to send everything flying a few inches. DO NOT LOSE ANY OF THE PARTS. YOU
WILL NEED TO RE-USE EVERY THING EXCEPT FOR THE CENTER NUT! New center nuts
are provided for all four struts/shocks. Here is a picture of everything
disassembled in the correct order.
O.
Next I removed the compressors VERY slowly a few turns on one side a few
on the other. I have heard horror stories about injuries so I was being EXTRA
careful. Then I put the new spring onto the new strut. You should be able to
read all of the TRD labels from left to right bottom to top once you are done.
The strut has a TRD sticker on it and the springs a TRD label on them. They
should not be upside down. A cool side note, if you look at all f the writing on
the struts you will notice one of the few parts in English shows KYB. Do they
make the struts for TRD?
Here is a picture of the completed assembly, along with some comparison shots. I
found that I did not need the spring compressors to accomplish the reassemble.
My weight pushing down was suffecent. Also note that the center bar of the
strut, mounts to a KEYED mounting hole in the dust cover/mountng bracket. Be
sure this is aligned correctly.
P.
So now all that was left was to put everything back on, except for the
sway bar I waited until I had completed both side before installing the sway
bar. I pretty much followed the reverse of what I have described here, and what
do ya know I got new struts, and springs in the front. Best of all I did not
have to pay some money hungry dealer $800.00. After one side was completed,
including the installation of the new stuff. I then moved over to the other
side. This way I always had a complete model to refer back to if anything got
confusing.
Part
II Rear Strut component removal & Installation:
Ok on to the backside. I was a wee bit tired at this point so I did not take as many pictures as I had for the front. Most of the work is very similar to the front.
Q.
The first thing I did was to loosen the lug nuts on both rear wheels.
R.
Next I removed the center cap over the strut tower using the standard
screwdriver. (please note I have previously installed the TRD Rear Strut tower
brace, so once again it does look a little different than a stock car)
S.
Once again I loosened the center strut nut prior to removing the
assembly from the car.
T. I then proceed to lift the car. Once more I did not use the center lift points for fear of not being able to get the jack out from under the car. Also I was unable to use my ramps on the front end. The car is to low now, and damage would have occurred to the bumper cover. So up front I placed wheel stops, and at the lift points on the sides went the jack stands.
U. I then inspected everything to see what would get in the way. I went straight for the sway bar. I disconnected the sway bar from the lower portion of the link, leaving the upper portion of the link attached to the strut. I then removed the Sway Bar Brackets, and Bushings. I did this on both the passenger side and the driver side of the car. Once everything was disconnected, I removed the sway bar from the car. This was nowhere near as difficult as the front.
V. Next I moved onto the Brake Line mount. Just like before I wanted to get everything out of the way that looked like it would get in the way. The following series of photos will show what I did up to this point, along with providing some reference.
Please not that the above photo was taken after the sway bar was removed.
W. Now that everything was out of the way, it was time to remove the nuts from the Strut connecting it to the axle carrier. These are in at 128ft/lbs. I do not have a breaker bar, so it was one foot up in the wheel well resting against the frame, and the other on the opposite side, a few grunts and off they came. Once again I used my trusty jack case to hold up the calipers, and discs.
X. Then the same as the front I removed the strut tower mounting nuts. Carefully holding up the strut/shock assemble while removing the last nut. And out it came with out a problem. Unfortunately I did not take any pictures during the disassembly. The first thing I removed was the Sway bar link. This is attached directly to the strut, and will need to be placed on to the new strut. Note that there is NO new bushing provided, so you will need to use the old busing. The spring compressors were used just like on the front. Once you have removed the center nut, the old dust cover pops right off. There is one part you do need to reuse. You will see it and know what it is. I do not know what to call it except for the Styrofoam looking spacer thing. If you look above in the front section part of this write up, just above section O there is a picture of the front strut disassembled. The orangeish thing you see on the end of the dust cover is what I am referring to.
Y. Once I had the old strut assembly disassembled, I reassembled the new one. Once again I did not find it necessary to use the spring compressors during the reassemble. Just like the front though; make sure you are in the “key” on the dust cover/strut-mounting bracket. Otherwise when you try to torque down the center nut you will just sit and spin. The following photo shows the fully assembled unit, (minus the sway bar link) along with the old spring next to it.
Z. Now that it was all ready to go back into the car, so in it went! I put everything back on at this time except for the sway bar. Once I was finished installing the new strut assembly, I went to the other side and did the process all over again.
AA. Once both sides were finished I then installed the new sway bar and bushings. While I was down there installing the brackets, I went a head and removed the plastic covers from underneath the exhaust, and the motor. [Editors Note: When installing the sway bars, there is an upward direction, and a downward direction. The Sportivo logos should be facing the ground when the bar is installed. You will also notice that the ends of the sway bar are not perfectly vertical, they are slightly canted. If you install the sway bar backwards, the tie rod end links will bolt up to the sway bar at a funny angle - you must remove and reverse the sway bar if this happens. The sway bar end links move like a tie rod end and may bind if the sway bar is installed backwards. The rear bar is obvious if installed backwards, but the front is not so obvious. Also, the slits in the sway bar bushings should be aligned so that the slits are facing downward when installed. The bushings should be mounted so that the line of the split points forward for the rear bushings and rearward for the front bushings, if they are in wrong the split will be pointing up.] Here a picture of the completed install with the new sway bar.
BB. Last and not the least was installing the member spacers. The instructions are in English, but I was unable to follow them to the “T”. I do not have a transmission stand, so I substituted my jack for the stand. I brought up the jack and just kissed the under side of the member directly below the copper nut from the first photo below. I did one side at a time, but I found it necessary to “slightly” loosen the opposite side from which I was working on, in order to get enough clearance to slip in the member spacers in. [Editors note: I had the body up on jackstands and used the floorjack at the center engine mount to hold the member as it was slightly lowered to slip in the spacers.] Once they were in I used a small screwdriver to align them. After that I threaded the bolts in and torque them down half way. I did not want to fully torque down on the first side because then I would just have to loosen them up again. I then moved the jack over to the other side and did the same thing there. Once everything was In I torque everything down to spec.
CC. Next I put all the plastic covers back on, put the Spyder back down on the ground, put away my tools, went for a quick spin to see if I could here anything strange, or feel anything wrong. I was not gone for more than 5 minutes, before I returned to the house and began my night of anticipation. My 4-wheel alignment/wheel balance was scheduled for 7:30 am the next morning. I did not want to go out and start driving without having those done. Needless to say I was up bright and early the next morning.
Part
III Post Mortem:
Out
with the old Splat, in with the Bionic Splat
After the alignment and wheel balance were completed. I was off to work. For those of you who know California, I live in Ben Lomond; the closest Toyota dealer is in Santa Cruz. I work “over the hill” so my daily commute is on HWY17, or 9. I figured 17 was as good a place as any to break in and test out the new suspension prior to hitting my favorite stretch of local road HWY 9. So when I left the dealer around 10:00am or so most of the commute traffic was gone. Sweet open road… WOW!!! OMFG!!! I have never felt this good driving over 17 before. The slowly fading perma-grin returned in full force. I could not wait until I was off from work so I could take 9 home!!!!
