Question for all you Z-71 owners just bought a 00 Z-71 to drive daily and tow my soon to be race car. it is suposed to have come with 4.10's and a locker option in the rear. is it normal to hear the locker engage and disengage when you start and stop. i drove a few and all have a little more noise that the 2wd's starting and stoping. drives fine and everything works in 4wd. no gear noise. is this normal for the new Z-71's with that option.

the trucks come with a g80 and i believe it is a limited slip. it does not make any noise. I can tell you that i believe you have the well known drive shaft clunk. you can grease it and it should go away but will come back.
The truck does not have a truc locker unless it is aftermarket. I am guessing and judging by what you said it is happanind when leaving a stop and comming to almost a complete stop. A locker clunks every time you get on and off the gas. there is some more info on this and i belive to solve the problme compleetly not temporarly you have to change the yock or something.
Post any more ?? you have in the truck section we have a very knowledgable group of guys.

sleepersilverado is right, there is a hugh problem with drive line cluck with 4WDs. it is due to the slip yoke being lubercated with transfer case fluid and not ATF. we have tried many things at the dealer to try to fix this (lubercating with special lube, changeing transfer case fluid to a different type, pluging hole at end of yoke, and even replaceing the yoke with a better desing). no matter what we did more then 50% came back with same problem. finally GM came up with the perfect fix, they put a bullition out that called this normal driveline noise. so bacically, your screwed. also, there is a true locker avalibale as an option. they work awsome but if you floor when stuck they will automaticly disengage to prevent breakage.
