I have a bit of a clunk when going over bumps coming from the rear. I brought the car to a suspension guy and he didn’t find anything wrong. We went for a test drive and he heard it but didn’t know what it was.

2013 TL with 128k. Struts have never been done. I was thinking of doing the struts but the guy said they weren’t bad.

Any idea what it could be?

Also, if I do just replace the strut and not the whole assembly, is there another part of that that could be rattling?

Here’s a clip, you can hear it around 7 seconds. Kind of a mid-rumble.

Can you host it on YouTube instead?

There are a lot of moving parts in the rear suspension. The most common noisy component is a bad sway bar end link.

Does it only happen when ONE wheel hits a bump? That points to a bad end link.

You can test the theory by disconnecting one end link and going for a drive. If it cures the noise, you likely found the issue.

If you need to replace anything in the suspension, I strongly recommend buying a factory part from a dealer. Aftermarket parts won't work as well or last as long as a factory part.

I thought either struts or end link. Frustrating the mechanic couldn’t find it.

I try to avoid certain brands when getting parts but dealer parts are outrageous.

I used Aisin for the timing belt for ~$180. Dealer was going to be over ~$600. Still used dealer coolant though. Dealer transmission oil & filter too.

If a brand is good enough for Toyota/Lexus to use as OE, it’s good enough for my Acura.

With parts, it depends.

Shop at dealer sites like curryacuraparts.com or hondaautomotiveparts.com

Price differences betwern factory chassis parts and aftermarket are not outrageous when you consider the massive difference in quality. The factory part (whatever is making noise) lasted you 128K miles. An aftermarket (whatever is making noise) won't.
