How to remove Rear Differential.
I have a 1992 f150. I am replacing the rear differential bearings. I have removed the cover, drained the fluid, pulled the pin, removed the c-clips, pulled the axles and now am confused on what to do next.
Do I remove the 4 bolts that holds the collar on over top of the bearings? After the 4 bolts are removed, does the differential slide out.
I am no mechanic but I think I can complete this job. I just ordered a differential repair kit, National Brand, part# RA-311. The parts store said it had everything in it to complete the job.
The reason I am replacing the bearings in the differential is because I was getting a vibration and upon inspection of the rear end, I put the truck on jackstands and with my hand spun the axles and a thumping sound is coming from the differential area that speeds up the faster I turn the axle by hand. You can also feel the thump on your hand. My neighbor said it is probably coming from the differential and to replace the bearings.

Did you take off the pinion to drive shaft flange? After that, yes remove those 4 bolts and the internal gears should all just come out of the housing. But, if you will reuse the old stuff it has to go back in the same positions, just like crankshaft bearings do.

In general the main differential bearing never fail.. I have never seen or heard of one failing as long as the diff has oil in it anyway. It is more common for the outer bearing to wear and with high milage trucks the bearing surface on the drive axles also wears down. You're seconds away from inspecting these now so go ahead but also get a bearing puller and change the outside bearings and seals even if you don't end up replacing the diff bearings. That have to be pressed off and on by the way.
