I have a 99 TL that makes a clunking noise when driving over a very bumpy road surfaces. The noise comes from the front end and I suspect may be from lose suspension part(s). I have taken it to a repair shop twice for this issue and they say nothing is wrong.

Does anyone have any ideas?

Thanks.

 

Did the mechanics guess of what the problems could be? You have a few things to narrow down the problem:
1. Struts
2. Bearing
3. U-Joint
4. Ball Joints
5. Loose Lug Nuts
6. Bushers

Maybe some else can chime more in. it would be hard for someone to help you with your problem description.

 

Most commonly its a ball joint

 

Any suspension mods?
