I noticed your site does not have the tundra listed under your make model search engine.  At first I thought you just didnt make a poly bushing for my rack pinion steering rack that is moving all over the place and wearing out my new tires.  Then I went to the wheeler offroad site and they listed your product for my year and make as a 8.10104G.  Am I to assume this is correct or is wheeler in error?  Am I doing something wrong inputing my information on your site??   I also read in another sites forums that these poly bushings for my truck where not molded correctly and need to be shaved down a bit before installing.  Has this problem been resolved?

Alligatorgar,

We have not updated our site quite yet to show those part numbers but yes we do manufacture the rack & pinion bushings for your Tundra.

Part # 8.10104R is the one you'll be asking for. 

To date I have not heard of any complaints concerning the bushings not fitting properly.  Our urethane is designed to have a very tight fitting installation for pre-load and proprietary set factors.  Let me know if you have difficulties and we'll try and clear this issue up Smiley

Thanks!

Hey Jeff thanks for replying.  I went ahead and ordered, then installed the rack bushings.  Yes they tightened up the rack however the large D bushing does still have some movement which concernes me a bit.  I also noticed the original metal insert for the middle bushing was serated on the ends and the new metal bushing insert were not.  Is this going to be a problem?  I did make video and am in the editing stage before posting it on youtube.  I thought Id get your feed back before doing so.  I was also doing a write up on this project on Tundra talk forums.  Heres what Ive written so far.


02’ Tundra ac sr 4.7 with 71,000 miles

So I changed out my steering rack bushing this week and thought Id post my experience.  I won’t bother with the obvious (jack up the truck, use blocks) because that has already been covered in other post.
The first mistake I made was the middle bolt (vertical)  is removed from the top of the rack and not the bottom.  That bottom nut is welded to the frame.  Sorta hard to see this with all the dirt.  I stripped it trying to remove it.  Opps!  I think I moved the truck trying to turn it.
After loosening all the bolts I cut the old bushing end off the drivers side bushing (horizontal) (bushing side facing the rear of truck) and stuck a small screw driver (small ice pick would work good too) between the bushing and housing and wd40 it up really good.  I then grabbed the washer that is attached to this bushing metal insert with a pair of channel locks and wiggled it out inch by inch ( this washer is facing the front of the truck between the rack and the truck frame). 
I then cut the top of the middle (vertical) bushing off at the top and ran a small screw driver between the housing and bushing and sprayed with wd40.  I then put a vise grip on the metal insert and wiggled it out.  Clean up was easy with brake cleaner.  The passenger end bushing is a breeze to remove and reinstall just be sure to clean rack up before reinstalling.
After cleaning the rack up I installed (grease these new bushings up good so you don’t have any squeaks) the drivers side bushing first by hand then with a glue clamp.  I then installed (pressed) the metal insert into the poly with the glue clamp.  I repeated this process for the middle one also.  Everything went together pretty easy from here on out.  I loosely bolted the drivers side first then the passenger side.  I lined the middle up and tightened the drivers bolt which lined the middle bolt up perfect (middle bolt is tapered for a reason).  Tightened everything down then tested it out. 
The passenger rack still moves a little but nothing like before.  The drivers side is rock solid.  I had the truck aligned a week ago (before the install) and only had 1,000 miles on the alignment.  I took it back to the shop after my install and was told the right front wheel was out 30 degrees and the left 10 degrees.  I’m not sure why this was considering I didn’t break the tie rods up.  Guess moving the rack around can mess the alignment up. While at the alignment shop there was a 02’ tdr ac with 170,000 miles on it and that trucks rack was rock solid.  I talked to the owner and he states he has never had trouble with the rack.  His truck clearly was used and abused more than mine so go figure. 

The steering is tight now with no slop at all.  However the drivers side D bushing does have some movement.  This concerns me a bit and I will contact Energy Suspension and ask about this.  They have a forum and product support here that seems to be manned.   

Note: I used this forums instructions as my guide.

As a afterthought I was wondering if you could post all the bushings you offer for the 02 tundra.  A number of fellow owners are looking for a complete bushing kit for this truck.  Any help would be appreciated.  I will post my findings in the above listed forums.

This is a great write-up!  I can't wait to see the video.

I am checking with my engineering dept. to answer your questions, thank you!

Unfortunately Im a total newb at creating video Tongue.  Im sorry to say I used my digital camera to get these images and uploaded them on youtube.  My concern is the movement in the passenger side new bushing replacement.  I know that the left to right movement can't be much because the drivers side is not moving around much.  That leaves the middle bushing and the passenger bushing to move around a bit more than I would like.  What do you guys think??

Ron,

I appreciate your patience on this one.  I wanted to make sure I had my facts strait with my engineering department to insure I wasn't talking out the side of my neck.  Engineering has confirmed that a small level of compliance is necessary for the Driver Side D Bushing to provide minimal resistance for the other load bearing bushings and brackets.  Any less compliance could result in breakage from the other components pertaining to the rack assembly.  There's a lot of pressure and torque when the rack & pinon shift from lock to lock so using a softer durometer urethane and applying the correct amount of material for isolation the D bushing provides a good medium between isolation and durability without the compromise.  To simplify this the D bushing is manufactured from a softer material to allow proper compliance.  Where as the flange bushings, also included in the kit, are made from a harder urethane because they do not serve the same purpose.

As for the serrated edges, those are generally manufactured to secure the sleeve and prevent it from rotating inside the brackets which would result in tearing the rubber bushings.  Our bushings are full floating so tearing is not an issue and locking that sleeve in place is no longer necessary.

I hope I have answered your questions appropriately but if I have fell short of giving you the answer you were searching for please give me a shout back and I will do my best to respond.

Thanks again.
