thanks

 

My brother has the URAS pineapples (4 Urethane collars). He complains about diff whine, but its not that bad. Anyone with the aluminum collars want to trade? I hear that they aren't as loud.

 

I tell you what, if you have the time to put in the soild bushigns its well worth it, but you have to drop your entire subframe.

 

yea i know im gonna do the sub frame bushing when i swap diffs with lsd thats why i asking

 

i mean the whole rear end not swap the diff diff but the whole housing

 

plopokiller,

doing the full subframe bushings from SPL parts is a very big pain.

The tolerances are so tight, you have to put the bushings in the freezer so they slide in easier.. tightnening the subframe in with the aluminum is a very slow and tedius process. it barely wants to fit on !!!

the noise and vibration harshness is about as bad as it can possibly get with a solid mounted diff now mounted right onto the body of the car. but the performance benefits are awesome!

good luck!
