How to pull limited slip differential axle - 1999 Chevrolet Silverado 1500

limited slip differentials are so designed that when one axle looses traction the pressure is applied through the side gears to lock up diff so that both wheels have to turn. If it slips in reverse then in will slip going forward . I would be inclined to look for a reverse gear problem in the gear box/ transmission. If it is an auto check for reverse solenoid operation.

which system?
we cant guess what is In YOUR CAR, ever.
you must SAY. or RTM, in the glove box.
and why are you using 4wd on dry pavement, now>?


4WD: Select-Trac (or older Select-Drive has a slip coupling too, NP129/229) is AWD in that, "the "4Hi" setting the drive shafts were coupled together using a viscous-type coupler " this anti wind up slipper"
Watch out for exception 1: Select-Trac NP228 based jeeps, it does not have a viscous-type limited-slip coupling. It was used briefly in 1986.
Quada-Trac is full time 4WD (not in lock mode) has a real center differential to shift torque between front and rear. This is the best system , not just a slip clutch as above. Then went BACK to the slipper in 1980. (odd huh?) Up to 1998.
Quadra-Trac-II "4-All Time", "N" or neutral, and "4-Lo". In "4-All Time", torque is applied to the rear wheels under normal driving conditions.
If the rear axle starts rotating at a significantly higher rate than the front axle, hydraulic pressure builds up in the gerotor oil pump and causes the clutch pack, to progressively transfer torque to the front axle, until both axles return to the same speed
Quadra-Trac I was introduced in 2004-10, same as above but is automatic with no driver controls ,like above.
The Quadra-Drive system was introduced in 1999 and is based on the Quadra-Trac II system but adds limited slip differentials (the best full time system ,with great traction to all wheels all the time) 1999 to 04.
Quadra-Drive-II has electronic limited slip differentials or ELSDs 2005 up.

I supose you are talking about the rear axle? if so, unscrew the bolts of the rear axle's cover and let the oil flow out into a container. once it's empty, clean the cover and the surface on the axle where the cover goes on to, apply a seal onto the cover and put the cover back on and screw al of the bolts back into place and tighten them. you will find a rubber plug in the cover, take it out and fill the rear axle untill the liquid comes out of the plughole. Put the rubber plug in and you're done! Watch out if you got al limited slip differential, you will need to put an additive into the oil so you won't burn the clutches of you limited slip differential.

yes. Remove the C-clips inside the housing and pull out the axles.

Thank you for using fixya and good luck

It sounds like your limited slip differential is in need of a fluid change.
The clutch packs in the axle require a special friction modifier,about 4 ounces added to the axle lube,which fixes the chattering issue.
I'd suggest someone drop the axle diff cover and check or change the
fluid,to see if there are any big metal pcs. in there. If there is no damage,drain the diff fluid and add the friction modifier,only if a SLD..

Note: Only add the friction modifier,if you have a limited slip differential.
Since I can't physically see your vehicle,make sure a mechanic does
it right.

Mopart Synthetic Gear Lubricant 75W-90
NOTE:
Trac-Lok T differentials require Limited Slip Additive in the lubricant.
Trac-Rite differentials DO NOT require Limited Slip Additive.

remove rear cover from rear differential. catch nasty smelling oil (gear lube) in drain pan. remove bolt on side of carrier to be able to pull pin out from so called spider gears. if you have limited slip you may hve to pull S spring out from between side gears. then push axles in and remove C clips fom end of axles. then pull axles out. installation is in reverse of removal. make sure that the C clips are well installed in the groves whe reinstalling axles, or they could fall out and axles will come out while driving. bad deal.if you have limited slip get a bottle of friction modifier from parts store to put in there with new gear lube . is a small bottle like 6 to 8 oz.kepps clutch packs from chatering on turns.

Not that difficult, raise and support the rear of the truck and remove the wheels. Might as well replace both sides so you know you have new seals, remove the differential cover and drain the fluid. Once differential is opened and cleaned , remove the axle "C" clip that hold the axle in place and slide the axle out. Once the axle is out remove the wheel seal and clean around the area. This would be a good time to replace the wheel bearing too since you have access to them and there not that expensive. Install the new bearing and seal, note make sure you oiled the bearing and seal before installing it back and take care when installing the axle back in and "C: clip. Use RTV silicon gasket maker to seal the differential cover and wheels back on and lower. If your lazy like i am, you can drain the differential fluid and replace it with a 50/50 mix with gear oil and Lucas engine oil additives. That may stop the leak and get you a few more miles. You gear oil is 75W-90 and the capacity is 2.6 liters and 3.6 liters if you have the 11.50 Ring gear. Good luck and hope this helps.
