I have a 2012 mustang conv. base model and when i go over bumps i hear a clunking/grinding sound in the front end. I just had my front bumper repaired after a minor accident where a kid backed into me. Today was the first time having to hit bumps since i got the car back on friday. Anyone know what it may be???

Possibly control arm bushings. There is a TSB out for it, but they can make a clunk sound and replacement is the cure. Lots of people mention it about going over speed bumps. I've had it happen a couple times when going over them faster than I should.

Otherwise, you just have to check where they made repairs and make sure something isn't rubbing. Might be as simple as a clip came loose and is rubbing on something during big bumps.

I was think the bushings but, i was also told it could be the actual LCA. I looked at the TSB's and didn't see anything for bushings for the 2012 models. Either way its going into the dealer soon since its still under warranty. Thanks for your help

Did it clunk prior to the accident? If not, then something is loose. I had the front bumper cover off of my 2011 two weeks ago to install a GT type setup. There isn't much behind the cover that could "clunk". There's a styrofoam type piece that insulates between the metal bumper and the bumper cover; I could not see how that would "clunk".

I'd take it to the shop that did the repair, have the repair tech or body person go for a ride with you and have then check it out. That's of course assuming it did not clunk before the accident.
