Calling All Gen 1 Experts
I've got a 1991 LS400 w/ 81K miles and here's my problem. When driving and especially when coasting I feel a "rubbing" or slight vibration through the steering wheel and gear selector. I've already replaced the trans mount but the feeling is still there. Do you guys think it could be motor mounts or something else. Thanks in advance for your input.

It seems to remain constant, not really affected by speed. We have determined that new control arm bushings are needed and I've got them on order. Could it be the worn out CA bushings causing the problem. I guess we will see soon enough. Thanks

Ok guys, no flames please, but WTF is a Prop Shaft Bushing. I have searched and don't find much information at all on where/what it is or how hard and expensive it is to replace. Thanks

Have you had any aftermarket parts put on your vehicle lately (other than cosmetic)? How long have you been having the problem for? Have you had any luck identifying the problem?
My car cruises effortlessly on the highway (70-80mph). Every wheel has been checked and rechecked for balance. I even put four new Michelin's on the car and the same vibration is there afterwards. It also has all new brake pads and rotors (all OEM Parts)...
It feels like its coming more from the back than the front but its very difficult to tell for sure. The only vibration felt through the steering wheel is very slight when its happening... Definitely isolated enough through the steering wheel to rule out it being the root cause.

if you have any suspension problem, take it to your shop. if you have a good mechanic they will take it up and figure out what it is. it could be a whole bunch of things. I use one shop for my lexus and they will look at it for free. as a matter of fact, i am getting one lower ball joint, wheel bearings and upper control arm changed. but they only way to know what was needed was to have them lift it up, and inspect it, which they did for free. good luck

After driving it some more today, I must say that the overall smoothness of the vehicle is better, but I still have the same vibration, especially at 25-30 and maybe a little less now between 45-55....
I've been dealing with it for a year and a half now. This is a third Lexus (play) car for me. I may wait a little longer to see if it gets any worse on its own and therefore easier to identify as time goes on...
Now I'm leaning towards the differential bushings... From inspection, they can't find anything else wrong.
