    02 Chev Z71 4x4 - Sharp turns, pulling into parking spot or just general sharper turns - Loud - very loud bang bang bang from the rear of the truck. Any ideas just started today - I wonder if the old 84 k5 10 bolt will fit in there if it goes on me. any ideas.... Truck only has 75,000 on it

    Well , a locker could do that , and they do , and its normal .

    However considering its a factory ( assumption ) rear , its probably broken . They are supposed to be stronger on the newer ones .

    Either way its time to open it and look at it . Take a pic for us .

    Dose it have a factory locker? My brothers 2000 sierra locker blew apart with 52,000 miles on it a couple of weeks ago. He called me and said there was noise coming from his truck so I went to see what was wrong, took the dif cover off and seen a 3 inch whole in the locker and a gear in several pieces that nicked the ring and pinion gear.

    Welcome to the Gov-Bomb world ! You most likely have a GM Gov-Loc in your 10 bolt and it will die a violent death one day. What is happening is that it is staying locked up for one reason or another and you are feeling it strain/ratchet/moan-n-groan when taking a sharp slow corner.
    There are those who have dead G/L's and then there are those who will have dead G/L's - rest assured yours is slowly going to die if it is staying locked up. Replace it , or better yet upgrade to a better L/S before you are stranded.

    Find a 6-lug 14 bolt 9.5. It's a direct bolt in and a lot stronger than your 10 bolt for about the same price.

    I had a 2001 and it done the same thing. It broke the little bolt that held the cross pin in. If you catch in in time you may save the rear. If you let it go like i did then the rear diff cover will look like a strainer when all the crap starts poking though.

    Not a bad ending to the rear end story

    I ended up bringing it back to the chevy dealer where I bought it from - you guys will enjoy this - after they had worked on the truck for about an hour and a half test driving pulling the rear diff cover and poking around the service lady calls me back with the we didnt find anything wrong - the fluid was just a little low and then continues on to try to sell me some service pack, while reviewing this with me she says after 122,000 this, this and this needs to be done, I found this interesting since I only had 73,000 on my rig. They had been working on the wrong truck all morning. I couldnt believe it, I was a little pissed at first for them waisting my time but then couldnt stop laughing about it. Hard to believe but not that hard. So after they test drive my chev she calls back and it sounded like it actually totaly locked up on them when they were test driving it. She said the tech pulled the diff cover and got in to it - her exact words "your spider gears are blown to pieces". The other words that were music to my ears "your warrenty covers this so all you will need to pay is the $50 deductible" finally after all the warrentys I have purchased over the years one will pay off.

    once in a lifetime

    Pretty cool that it actually blew up while they were driving it.Usually you'll take a car in to have it looked at and it will quit making the noise you were worried about or whatever and you'll be left standing there like an idiot.Cherish this moment.Only bad thing is your bomb is still ticking. :frown1:
