I recently started noticing a moderately loud pop when going over a curb, like from a driveway to the street. It happens when the car is about half way through the elevation transition and it sounds like it is coming from the rear passenger side but I didn't see anything obvious when I poked around the area...

Any suggestions?

 

OK ... it might just be this: http://techinfo.honda.com/rjanisis/pubs/SB/B09-019.pdf

 

Would be my guess. We had a similar situation on our TL when new, but it was in the trunk meeting the wheel well from what I recall, was a long time ago.

 

So I talked to Acura and they said this usually happened when the cars were new.

This started immediately after an autocross event. Ive also discovered it happens when I turn with some speed (like 25-35ish).

Any ideas on components to check? Acura said they'd do the fix but also said they might damage paint in the area... Which is the rust guard paint.

Edit: I've had two shops look and they can't find anything relevant going on

 

Inner and/or outer tie rods, sway links, control arm or sway bar bushings, those are usual suspects when it comes to banging and clanging under the car, those parts tend to wear out if slight hooning is involved while driving or just lotsa mileage on shitty roads.

 

Hmm, well, I've had all those parts checked out by Acura and a local performance shop I frequent for suspension related things.

I'm going to put it on some jack stands this weekend and poke around some more.
