How do you a Replace rear axle seal on a 2WD 1996 Silverado. I have an oil leak dripping onto the iside of me left rear tire.

You must replace the axle seal.

if your talking about the rear brakes its probably the differential axle seal that is leaking differential oil out of the rear end onto the brake shoes. you will have to pull the rear axle to replace the seal and clean the rear brakes/area with brake cleaner or replace the rear brakes if they are too soaked with brake fluid.

you will have to dimantle rear hub withdraw driveshaft and replace seal oon axle drain axle oil first square drain plug in centre of axle hope this helps

You have a leaky axle seal. Sometimes this is cause by the vent or breather being plugged. Sometimes they just wear out and another cause is bad bearings. Either way the axle has to be pulled and seal replaced.

Where is the leak? Toward the middle or at the right or left sides near the rear wheels?

replace the power steering pump, the hoses are an odd size and you have to buy a wrench for it, the transmission you can change the gasket and filter and replace the fluids,, probably the engine is dripping from the rear main bearing seal, this is best left to someone who knows what they are doing.

remove the brake shoes, should be 4 bolts holding the axle in, pull out axle and bearing should be there also replace real seal

Hi,

That engine will leak oil from

- cam cover gaskets (rear one drips on the exhaust)
- camshaft end seals
- distributor shaft o-ring (appears on top of transaxle housing)
- oil filter bracket to block o-ring seal (drips on front bank exhaust)
- crankshaft nose oil seal (have done with timing belt change)
- rear main seal (expensive, leave it be)

Hi..
On your 05 Chevy 4X4 2500HD.
The Pinion Yoke Nut, 9.75" Axle. the torq spec. is 370 Nm. -- 273 Lb ft.

I hope this help on your question.

Thank you for use fixya...

You are correct, it's not brake fluid. Check the level in your rear axle, it sounds like you have bad seals in the axles allowing the rear differential gear oil to leak inside the brake drums.
This is a heavy weight oil, 80 or 90 weight. This leakage will ruin your brake pads, and if enough leaks out, your rear differential will blow. The seals aren't expensive, but it's a lot of labor to pull everything apart to get at the seals, plus new rear brakes. My Ford ( and I'm sure your GMC) require removal of the rear axles to change the seals. Good Luck! countrycurt0
