Hey guys,

I finally tracked down the rear-end clunk in my 15 GT.

Every time I would switch from forward to reverse (or vice-versa), and apply throttle, I would get a few clunks. I checked torque on everything multiple times, with the exception of the LCA bolt. I replaced my LCA with BMR BK081 a few months back, and that bolt is a bear to get to.

Noise:



Ultimately, I had to buy a 24mm shallow 6 point socket and an impact rated universal joint. I torqued it as tight as I could get it with a 3 foot cheater bar. Clunk is gone! Pics below.

LCA bolt from the outside of the wheel well:

LCA bolt from below and behind (this is where you tighten it fromā€¦ tight spaces):
