Is my locker breaking?

I have a 2004 with a 5.3 and the locking rear. About 17000 miles. Two or three times now, when making a left turn at slow speed, like into a driveway, the locker will lock and not release. You will feel the truck drag and hear the tires dragging because the locker is locked. It will release eventually when the truck is straightened out. The last time this happened it made more noise than usual when disengaging. Should I have this checked out (still under warranty) or is it normal?

still under warranty. why are you asking take it in for a check up. it should not cost any thing.

Everything you mentioned sounds normal to me. its a locker...JJ

hello huminski I have a 2000 silverado Z71 and the rear end just started the same locking problem as yours and its not normal or it would have been doing it all along sucks for me I have no warranty so when the dealer tells you what is wrong with yours it would be very cool and helpful if you can post it are e-mail me thanks alot

did you check the fluid level?

I got under the back of the truck pulled the fill plug to check and my finger was not long enough the owners manuel says from 5/8 to 1 5/8 from the fill hole I am going to try again I found online where a guy talked about using an allan wrench to stick in the hole to find the level

allen wrench works great.
