I have an 06 TL Automatic with A-spec suspension.

Lately I have been noticing a strange sound that I have not heard before.

I have owned my TL for about 2.5 years now.

When I am driving and I pass over perhaps a medium sized hole like a sewer drain (not a pot hole), I notice a hollow type of knocking sound from my rear suspension / wheels.

I have stock rims and wheels.

I cannot always replicate it but it is getting me worried. The dealer asked if I wanted to go for a test drive after I took off my winter tires but I had no time to do it and will probably go in again soon.

Any ideas anyone? I hope something is not loose.

Thanks.

Do they have rear shocks or struts? Sometimes a bad shock will make that noise when the travel hits the end. I think a strut will do the same thing. That would be when it's fully extended, not compressed.

rear shocks and bump stops. the bump stops need to be update.

probably your rear sway bar endlinks.

I have had this for about a year. I recently moved out of state and transported a weight set in the trunk, stacking the weights over the rear suspension towards the back of the truck. Two days later I removed them and the clunk is almost gone, as if it pushed it all back together. But from the passenger rear I have had a clunk for some time.

Someone did a diy write up about removing some bolts to the rear seats and sliding a socket with extension down behind the seat to tighten the nut on top of the rear pillar but the search is pretty bad and I'm having a hard time locating it. Good luck.
