its a 95z and i dont drive it but once a week or so but if it sets for more than a week when i go to back up there is a loud pop in the rear and it almost feels like something is froze up. the rear brakes look ok so i dont think it is the parking brake sticking but could be. i am afraid it may be the rear end. i had 4.10s put in years ago by a local gm dealer and it is a genuine gear but has always whined and to me felt like it had slack but the tech assured me the specs were right. any ideas guys?

 

anyone????? any ideas?????

 

probably your posi. Mine used to do that, before it exploded

 

ummmm, thanks for the positive input mike......i was afraid thats what it was...

 

 

you should see the chunks of torsen gears that fell out when we took it apart, as for the gear noise, you had a dealer install them, hey mike even a dealership cant get it right..... man look for a different shop or just make the trip to michigan and we'll set u up right.
