TYTE99LS

The likely reason is your wheels need hub centric rings. Are they aftermarket wheels? Hey thanks a lot for replying...I do have aftermarket wheels and the stock wheels. Regardless of what set is on the car its vibrating. I had the car inspected and again no conclusion! Im wondering if anybody on here has ever heard or had an issue like this. I cant keep trusting different mechanics due to the fact that it has been a waste of money so far...Im hoping someone on here knows Lexus's and can come up with a good conclusion on this one!

Sorry man, I'm kinda new to this. I had the transmission serviced, new struts, new motor and transmission mounts, new tires, tuned up about 5k miles ago. Just in a state of confusion not being able to solve this mystery. Ever heard of such an issue with the LS400?

First off I would like to thank the guys that gave me some advice, I really did appreciate it! But my issue has not been solved. OK, so heres the deal. I have a 1999 LS400. Somewhere between 0MPH and 15MPH i feel a vibration underneath the car. Now, the vibration varies in feeling depending on how much you get on the trottle. If I let off the gas before 15MPH, no vibration! The car has been checked by several "good" mechanics and I've heard many different things. Im on here hoping someone has had an issue like this and solved it. Every mechanic that put the car on a lift and diagnosed it and I was told there is nothing wrong. If anybody can give me any feedback on this issue I would really appreciate it! Thanks a lot!

Whats up man, thanks again, all was done about 5k miles ago. All the wires, plugs,etc were rechecked and they are fine. The issue has to be in the drivetrain, I just cant figure out where. You never heard of such an issue?

Hey fellas, again thank you for your ideas and support. I had the transmission seviced less than 1k miles ago. As far as the tires are concerned, they are brand new. The wheels were inspected and they are not bent and they were balanced. Its a confusing issue and I'm stuck. HELP PLEASE!!!

OK, first off I would like to thank you for replying! I really do appreciate the input. The car has new motor mounts, new transmission mount, new struts. Man I'm so confused. I took it to a different mechanic today and the result he came up with is that the issue is in the transmission, and that the vibration is happening when the transmission is up-shifting first to second. So hears the deal, if the issue was this then when I put the car in first gear so it does not shift up it still has the same issue! :o :o
