Hi guys,
I searched for this clunking noise in the forums but am not exactly sure what it is. I "feel" it around the pedal box and hear it in the front right to center floorboard area going over rough roads and bumps. Seems like it would be right underneath the front center footwell area.

I just replaced the struts and mounts, I also had the sub-frame torqued to specs.

Any other thoughts (UCA, LCA, bushings, etc) that you think I should try next? I read a few different solutions but wonder if anyone might have the "oh yeah, that is definitely ....."
Your brains may help save me some money I really don' have. Thanks again!

dead trans mount and/or loose front subframe.

Clunking is a classic sign of a busted motor mount. the rubber separates from the metal. You will not know it till you remove the engine mounts. The mount will be in 2 pieces(you will be amazed at how you were driving for so long and your engine wasn't bolted down to nothing).

Thanks guys. Forgot to mention that I replaced the motor and trans mounts last month before the struts.

Just had the subframe torqued this weekend.

Any other thoughts?

Appreciate your help.
