Help! Clicking after Diff upgrade
 

Bought a Z1 built Qauife LSD with 4.08 gears and replaced bushings with Z1 urethane. After installation, I took the car out for a test drive. At first, I noticed clicking noises when coming to a stop and turning. Went home cus Engine light appeared. Did an ECU reset and cleared the light. So I went for another test drive and now, the clicking noise is more consistent. What could be wrong?

So now I’m thinking it’s gotta be transmission/driveshaft issue. I had bought a custome aluminum driveshaft and installed it. Due to Z1 messing up my differential order (driveshaft flange didn’t match up with diff flange due to tech/rep miscommunication) I swapped back to oem driveshaft and fitted my new diff today.

When I drive and decelerate, I hear the clicking noise.

I know this is old, but check your axle nuts

Fixed it. A bolt connecting driveshaft to diff wasn't torqued all the way. Thanks tho
