Scratchy Noise and Peddle vibration
 

Solved: Dented passenger side sway bar bracket

Background:
Hey guys, so I just recently hit a pretty decent sized rock and it sounded bad. I checked to see if anything fell off or broke but I did not see anything wrong in the engine bay and nothing hanging underneath the car.

Issue:
Now when I step on the throttle from standstill I hear a weird scratchy/sandy noise like something is dragging and a weird vibration on the gas peddle for a second or 2 then no vibration and sound. This was not there until I hit the rock. When I do a gentle start nothing vibrates or makes noise only when I do a harder start I hear and feel it. If I WOT while already moving the issue is not there and nothing while revving in neutral either. Any thoughts?

Specs:
2014 frs Mods: full exhaust, aftermarket wheels

sounds to me like you damaged either the driveshaft or one of the axles. Also it could be that you damaged a brake backing plate and its touching the rotor, but being that you say it happens when you get on the gas, I would be looking at the driveshaft or one of the rear axles. Just a guess, but its based in logic

It also sounded like glass breaking (might be hearing things) too but no visible glass is broken and nothing leaking either. But what you say makes sense might have to go to a shop. I went under my car today to look if any heat shielding might be rattling but nothing. Thank you

I'd guess that something (like a heat shield or under panel) came lose or got bent by the rock. Maybe it only "hits" when the engine is torquing over.

I'd suggest you get your car up on a rack and look for something that may be hitting when the engine moves in the torquing position.

Bubba says to take a crowbar and bend away anything that looks like it might be touching something else - :iono:

pedal

@humfrz and @JohnH so it turns out I dented the passenger side sway bar bracket. Thanks for the responses for possible issues.

Begone. Peddle your spelling corrections elsewhere!

front or rear? and what was it touching?
