Couple weeks ago I noticed a rubbing noise at WOT in 1st/2nd. Turned out it was the pinion hitting the body!
The culprit, worn out diff bushings. Think hotdog down a hallway.
The solution, polyurethane. I did the front bushing last year when I did the subframe reinforcement, so just rears this time.
Step 1, uhhhhh fuck, drop the pain in the ass one piece exhaust.
Diff out, old bushings out, new bushings in.
And back on the ground and ready for more launches.
