The rear axle takes 85-140 gear oil if you have limited slip you have to also add a friction modifier to it. you have to fill it from the level check plug about halfway up either on the differential cover or on the front of the third member depending on the axle that you have

    you check the level from the same hole you use to fill it it should be right at the bottom edge of the plug the friction modifier comes in a tube and is available at any parts store if you are not sure if you have a limited slip diff you will want lift both tires off the ground and get it into nuetral no brake on and turn one while looking under the car if the other one turns opposite direction you are turning the one no limited slip if they both turn the same way you do have it.

Need to change rear seals in axcles how to? 98 gmc jimmy


First i would check to see if the axle air vent was clear if its not the oil is vary heavy and expands a lot this will build up pressure inside the houseing and cause the axle seals to leak if you can clear it the problem may fix it self its 80 90 weight oil thats thick stuff. If not you need to remove the rear wheels and brake drums then you have to remove the cover from the rear carriar catch the oil. Look inside the carriar houseing you will see the ends of the axles theres a small clip on each axle called a c clip remove them you can pull them out with your fingers. Then you can slide the axles out past the brake plates pry the seals out you might as well replace the bearings when your doing but thats up to you. Lube and install the bearings then the new seals you will need new seals lube the seal lips and vary carefuly slide the axle in taking care not to damage the seal install the c clip do the other side put a new gasket on the rear carriar tighten bolts to 20 ft lbs. Refill carriar 80 90 weight oil through filler plug on the side of the houseing until it just starts to run out hole put the plug in the rear drums on and wheels

I changed my oil less than a month ago on my 1996 Jetta GL 2.0 and since then the oil they put had leaked out completely. I bought my own oil and just filled it up and it leaked out again. I took it today...


Hi
It sounds like the sump gasket is leaking, this can happen over time and with a car of this age is not unusual, the gasket should cost no more than say £10 GBP and labour would be about 1 hour max.

Hope this helps

I just replaced the gasket of the transmission pan and still have a leak on my 1999 chevy suburban?


The leak is coming from the pan ??
Maybe the leak is traveling to the pan seal area from somewhere else ?
Did you scape off the stuck-on old gaskit on trani and pan ?
Its customary to use gaskit sealer on both sides of the new gaskit..

How to adjust parking brake on a GMC Sierra 2500 HD Duramax 4wd?


The adjuster is just like on a car with drum brakes. It can be adjusted with the wheels still on the truck, but if yours is out enough that it doesn't work, an inspection is warranted. Axle seal failure is common and will soak the shoes.

Jacked both rear wheels off ground, and while slowly spinning wheel, tighten the star-wheel adjuster until you just hear and feel brake drums rubbing, then loosened slightly.
There's a plastic dust cover about 1/4" X 1" that you remove, and use a drum brake adjuster tool.

The driverside access hole is below axle, easily accessable. To tighten driver side rear parking brake, turn star-wheel adjuster down.


The passengerside access hole is found above axle, and difficult to see. Removed pass side wheel and used an inspection mirror.
To tighten passenger side rear parking brake, turn star-wheel adjuster up.

Good luck and hope this helps. Oh and the other thing to is that if you do smell axle fluid around the wheels and see oil leaking from the drum area. Then you have a axle wheel seal and or bearing gone bad too.
