Rear Gears Screaming?

Rear Gears Screaming?
Hey, I just bought a 1996 4Runner Limited 4x4 and when I accelerate, something in my rear end screams and whines very loudly. I was thinking I just needed to grease my differential? Any ideas?

The differential runs in a bath of gear lube, not "grease". To check the level, remove the upper plug and stick your finger in the hole. The gear lube should be just below the level of the fill hole. If it's low, suspect that a rear axle seal has failed, allowing the lube to leak out into your rear brake drums. This is a common failure in 3rd gen 4Runners, and requires repairing the failed seals, replacing the rear brake shoes and repairing whatever damage the lack of lube has caused in the differential. There is no way you can "grease" the differential.
For your sake I hope my guesswork is off the mark, as this can run into big bucks. Good luckl.

At the very least drain and refil the diff to see iif you can eek a few more weeks out of it. I agree though that it is not a good sign when you hear that. Try to pinpoint if the noise is from a rear axla bearing or actually from the diff. You should also lube all the zerk fittings on the driveshafts.

yea you better watch out. i had the same problem, and it was my carrier and ring bearings...if i would have driven about 2 more weeks, my rear end would have been done. you need to get this fixed asap, and drive as little as possible.
