I bought my burb 6 months ago and had all the fluids changed.My mechanic took care of the axle lube and said that it looked good inside and the gears appeared fairly new. and now i noticed today that when I turn the truck and then straigthen out the wheels and acellerate the rear end feels like it is a true locker with one side of the axle hopping.After getting straight it hops a few times and then is fine.whats going on?
 
Re: Rear end questions?

Why not just ask the guy that did the lubing if he remembers if there was a locker or open carrier.

Question is why did it never do this before?

I bet its a axle with a G80 code , and your Gov-Loc is going to die soon . Mine worked good wheeling , real good , was like an open on the street . About a month before it died it started acting like a locker or a spool around some corners . I would pull the cover and expect it while it still only costs the fluid and a gasket with some sealer . Mine thankfully got wedged together and held in the c-clips so I didn't lose my axles /forums/images/graemlins/k5.gif
 
Re: Rear end questions?

I'll check it out.What am I talking about for repair or parts needed?
 
Re: Rear end questions?

If it is some kind of clutch type posi it needs an additive as well as gear oil. Sometimes the rated gear oil for posi-traction isn't enough.

I asked my mechanic that did the fluid swap and he confermed he did put in the slip fluid.You can buy a OEM pcec product at Advance auto parts.He referred me to his buddy that spec. in rear ends and he said to add a little more fluid in and take it to the pavement and just do a bunch of hard circles in case the clutchs were locked up.Other than that it is prob. the Gov-loc.Well I did circles till I puked.No luck.Then I decided to do some really hard circles and punch the throttle to where the high side spins but the low side cannot due to the pressure on it.Sure enough after 3 times of this with the tire squealing, It broke free and is once again smooth as a babies butt!!

Just be prepared , if it is a Gov Loc , even if you think it will last on you ( like I thought ) , it WILL break when you least expect it . Mine let go the day I closed on my house /forums/images/graemlins/k5.gif
