Just finished replacing my rack bushings. 99 GS400 with 97K mi. At first I felt the difference. Nice improvement. By the time I finished a test drive down the local twisty road (old spicewood springs rd) I was used to it. Not a dramatic difference but still worth doing.
Discovered several things while doing it. First, when you use a screwdriver to pound out the metal sleeved bushings, use a screwdriver that is just a little bit larger than the metal flange. You're trying to push the metal, not the entire bushing. If you use too big a screwdriver, you cant hit it hard enough to get it out. Smaller screwdriver, you can just tap it out.
Second, 48 ft lbs seemed like a bit too much for the lower brace. I felt like I was about to strip the bolts. I will probably retorque them to 43 next time I'm under the car.
Third, for the metal sleeved bushings, you can pull them together as you're tightening them into place. If you have trouble getting the bolts lined up, just turn the wheels.
BTW, the diy instructions in this thread were great.

My old bushings were sort of still in one piece so using a small screwdriver would give the same result. The whole bushing wants to pull out with the metal sleeve. it does give more room to hit the screwdriver, but that was the only one I had laying around.
The 48ftlbs was pulled off of the Lexus manual. Of course accuracy of torque wrench, age of the bolt, whether or not the bolt was dry, etc all comes into play. Most important thing is to just feel whether the bolt will strip or not. In this case, hand tighten would have suffice.
It's a pretty good mod for the money. I hated how loose my steering was and with no OEM replacement in short of buying a new rack, these were the next best solution.

If anyone is interested, i just ordered the 3 steering rack bushings made by TRD straight from Japan, the cost was $30+20+$20+$40 Shipping from Japan = $110. Id rather go with the rubber than polyurathane for the stock feel.

You know what's strange, according to this diagram, look at item #2 it looks to be the bushing that we are looking for? How come it is listed as an oem lexus/toyota part now?
#3 was always available from Toyota.

Does the Daizen kit come with the metal sleeves for the bushings, or are you supposed to re-use the exiting sleeves?
i ordered my Daizen kit from TM Engineering , was not able to get a email reply from them on this question.
The 1st page of this thread shows what looks like metal sleeves that are new.
Also looks like the metal sleeves that the bushing goes around comes with the kit.
as you can see above the kit I got does not have the sleeves.
My car was already at the shop to do all the bushings and this meant an extra day wasted for Sewell to ship an armstrong kit that did have the sleeves as part of the kit.
As much as I'm very disappointed in TM ENg and Daizen both have shown utter neglect of their customer.
After unsuccessfully trying to get some answers or get the situation resolved with either of these companies I had to go and overnight the kit from Sewell which in the end was $80 extra plus now I have a $39 kit from Daizen that seems useless.
My hats off to the guys at Sewell that were able to fill my order and answered all my questions.
Which one of which was "Do you have the Daizen kit and does it come with metal sleeves?"
The answers was "no we no longer deal with Daizen due to supply issues".
My First impression on doing all the bushing kits, Steering Column, Camber Bushings, and sway bars.
Steering is slightly more taunt with a lot less play in the wheel. There is absolutely no loss of luxury the car is no harsher on any surface then prior to changing out the 110,000 Mile OEM bushings. Which in my case did not look to bad, read: California Garage Kept.
My biggest hope is this will solve my inside tire wear, only time will tell. I did do the ball joints about 30K miles ago and they were still good this time around.
Folks be warned TM Engineering might ship you a kit with missing parts. Don't even bother trying to contact them. It nearly impossible.
TM-Engineering if you are listening. I have purchased from you in the past and despite all the flack you take on this board was a faithful customer. You don't build that relationship by ignoring any attempted contact by your customers when problems arise. This is the surest way to not only lose reputation but also repeat business.
I will probably have to open a dispute with VISA.
