    Default 02 z-71 rear end problems

    today when i got in my truck and backed it out of drive way the rear end made a loud pop or clunck i didn't think much of it since it a gravel drive way . i thought maybe just trying to lock in rear end but on down the road it did it again . and when i turned to right it did it like 3 times as i was turning seems like it was trying to lock in ,but on down the road it did it at 30 to 40 miiles an hour . i was just wondering if its time for a rear end or maybe somethings wrong with the locker . hard to beleive it needs a rear end at 94,000 miles. any suggestion would be great

    Hey 02, welcome to the GM truck club. Since it did it 3 times going around 1 corner I would guess it's one of the spyder gears.
