Help.

Anybody know why those weights are bolted to the inside of the lower control arm mounts on the axle? (2012 Mustang GT M82 6 speed with the standard axle). I was looking for a way to attach a shackle to the rear axle to tie the car down to a trailer. Looked at a GT500, and it had some nuts welded in right between the LCA and the axle on the LCA mount. But on my GT there are these (I'm guessing) 2 lb weights bolted on there. I can't imagine what they're doing for us, but don't want to remove them until I know why they're in there.

Thanks.

 

NVH reducers.

 

canoe anchors, you know, just in case...

 

I removed them. Can't say I noticed any difference one way or another just added weight goes against my religion.

 

From a Ford Engineer that used to post here. He would often mention how different pieces were part of a larger 'system':


lower control arm bracket axle masses

They are there to attenuate axle whine. If you currently notice axle whine in your car in the 45-65mph range, it may increase a bit if you remove the masses. They are one part of a fairly extensive package engineered to address axle whine on the s197 platform.

 

I took mine off. Didn't hear an increase in noise. Dropped ~5 pounds.

 

Old thread I know. But here are 19x10 MRR-M350 wheels. S550 back spacing.
