I have a 1993 Lexus LS400 and have been experiencing some sort of clunking sound in the back when going over bumps, so I took it to a Lexus dealer to soon find out that the bushings that are located in the rear axle carrier connected to the rear trailer arms on both sides are worn out, and will have to purchase a complete unit (meaning new rear axle carrier with new trailer arms) in order to replace the bushings!!! As it is not sold seperately, I had a problem understanding this when it is just the bushing that are worn out and the rest of the unit is in mint condition as this has never been winter driven. So is this totally true? and is there any other alternative to this issue such as a polyurethane bushing kit I can purchase to save on cost as it is not practical to spend so much on something to become so little problem (literally!!!) I can understand if everything just became worn out @ the same time, but in this case it just did not happen this way. And what are the other bushing around the car I should keep my eyes and ears on, as I would also like to have them changed ( hoping I do not have to change a "whole" section of a car! ) I appreciate the help and advice.

 

The arm bushings are not available from toyota or any other manufacturer at this point.

You need to buy the whole arm which includes the bushing. Book value I'm told is about $90.

There is an aftermarket bushing company for Lexus cars which I've heard will probably have these bushings available within the next year (?) that's a guess on the timeframe ..

I don't want to claim anything for Daizen so I guess you could contact them directly and ask if they will make these to confirm.
