Replying to: lvrob (Jul 21, 2007 1:47 pm) I have an '05 I5 crew cab 4X4 and have the "locking " rear. Well 2 weeks ago, it went back to chevy because the rear really locked up. Coming out of my driveway. It took 2 weeks for them to get it back. They had to replace the complete rear (gears, bearings and clutches) It was under warrantee. It is really a 'positraction rear" (this what the service mgr told me). It handles much berrer on wet roads. Actually, I don't think the rear was ever right since I bought it new BTW, GM is not calling this a recall, they only have recalls for safty issues!

Replying to: fas (Jan 19, 2008 6:00 pm) Is it that optional Eaton rear end that has been praised in tests against its foreign rivals who don't offer the same kind of traction when the going gets rough.

Can I purchase a g80 locking differential for my 07 Colorado on line?
#11 of 11 locking rear / differential by srthomsen Sep 27, 2009 (7:29 am)
The automatic locking differential on the canyons/colorados is designed to sense a loss of or lack of traction at ONE wheel versus the other and will lock at the time that those preset parameters are reached.   It doesn't have anything to do with whether or not you can lay down 2 stripes of rubber on the road.   The automatic locking differential also will REDUCE available engine power when it is actuated. It works good BUT there are times when a locked axle & full available power can be an asset.   There needs to be a module mod to allow full power with the axle locked.
