The fluid splattered all over is most likely coming from the pinion seal. (The seal at the front of the differential where the driveshaft yoke goes in.) Normally, you would remove the driveshaft and the pinion yoke to relace the seal. The grinding however, leads me to believe that the seal leaking is a RESULT not a CAUSE of your problem. The way you describe it sounds like you may have some serious pinion and/or ring gear damage inside the differential.
If this is the case, there are severl ways to go about repairing this. You could tear your differential apart and replace the defective/damaged parts inside. You could replace your differential with a used one from a salvage yard. You could replace your differential with a remanufactured differential assembly.

To check for damage, remove the rear cover from the differential and check for metal in the oil and in the bottom of the housing. You can also turn the ring gear around and check for broken teeth. You can also inspect the spider gears and pinion gear for damage.

I have a chevy 2500 hd when i turn turn the rear wheels skip and bark


Chances are the locking rear differential is staying locked up and causing the tires to chirp/bark.You can try to fix this by changing the rear axle grease and then driving i circles both left and right about 20 times.If it starts to get better then try it for awhile.If not the rear locking DIFFERENTIAL MAY NEED TO BE REBUILT.Some other possible things to check before you go
and teardown the rear axle are-different tire sizes in the rear,the vehicle is in 4wd.

Suspect a worn left side spider gear or it's bearing in the differential. If a limited-slip differential, the left side clutch may be grabbing somewhat. In any case, the differential will need to be removed from the case to service any worn or defective components. Rear end service is not for inexperienced mechanics. Have you checked the fluid level in the differential? Hope this helps!

When i turn either left or right it sounds like my back end is going to fall apart. when i turn left my right tire stops and its bounces itself as im turning and when i turn right my left tire locks up and...


Sounds a lot like you have a positraction differential. If the unit runs dry or very low, the friction plates will bind together and begin to act like a "locked" rear, or spool used by rock crawlers and in drag cars.
I suggest you remove the rear cover, clean out any residue and re-fill with the proper amount of lube.
Posi units also require the addition of special posi additive.(add first so there is enough room for it).
After filling the unit, go into a parking lot and make a series of circles...Start with big ones and gradually make them smaller, alternating clock-wise and CCW turns. Generally if the friction plates aren't totally fried, they will begin to disengage like they were designed to do. If not, the unit needs to be rebuilt.

The problem sounds and looks like its in my rear end when i turn left or right my rear end acks like its locked in and my rear tire sqeel but when im driving foward or back it dont act up. it only does...


Sounds like you have a limited slip or " Posi-Traction" rear differential, if this is the case than go to the GM dealer and ask them for a bottle of friction modifier oil for limited slip differential. This stuff is pure whale oil that helps to lubricate the clutches in the differential. After adding the lube find your self a big empty parking lot or other paved surface and drive the vehicle forwards then backwards in a slow figure 8 patern, turn as tight as you can each way, this will force the clutches to work and help limber them up. The differential might make some crunching sounds, but the noise should quit as the lube gets in and does its job.

Rear end noise on 2002 Dodge ram 1500


If you have a positraction differential, you need posi additive along with the new lube. After it's in, take it to a parking lot and make tight left turns then tight right turns to get the lube between the posi plates. That usually frees it up unless there is an actual mechanical problem in the diff.
good luck!

When turning right or left and excelerating I get a noise in the rear until the car returns to a straight path.


That is a classic differential sound. But it may be sort of normal if you have a limited slip differential. I would not expect it to be very loud though, unless there was a problem. Being so new, I find it hard to suggest though. One way to be more sure is to only jack up one rear wheel. Then you will hear it at its worst. If it sounds rough, like bearing noise, then drain the differential and look for metal shavings. At least change the oil.
