I have a 2001 LS 430 that just turned 100K.


If I drive over a dirt or rocky road it sounds and feels like the front suspension is about to fall off.


I just replaced the tires with Michelin MXV4's and had the wheels aligned.


I asked that the front end be checked and was told it was fine. ( It's a local shop that I've been going to for quite a while and they have fixed all of my cars and I trust them)


On a normal road or on the highway at speeds around 80 the car handles and drives fine. It tracks well. And the shocks/struts seem normal.


But if I go over a rough road or pull into a driveway that has a 1 or 2 inch lip it bangs.


Any suggestions?


I also have a 2004 LS430 and I've read that there was an issue with the steering column. Could this be something similar with the 2001?



Thanks

Fran, there probably is nothing major wrong with your car and that is why the shop found nothing. However, isolating noises like this can be tough. I would find an empty parking lot with a speed bump or curb and drive over the curb making a right turn into it and a left turn into it. See if the banging is worse in one direction. If it is, then you have isolated the side. It could be that your shop overlooked a cracked bushing. I would also consider finding a shop that specializes in front end work, like alignments, and present them with your findings. You might even convince a service tech to ride along with you so that you can explain the symptoms and drive a road that you know makes the noise(s). It does not hurt to get a second opinion.
