F150 Rear end question
 

I was talking to my uncle today and he wanted me to find him a replacement F150 rear end for his '93. I looked around on craigslist for a bit and didn't see any.

Later I talked to him more about what exactly he needed and why. He said it makes noise, especially at highway speeds when you take your foot off the accelerator and coast. Howl, not quite, Heavy hum with vibration more like it.

The shop he took it to said "something about the spider gear and bearings being worn out"


From what he said it sounds like we could just replace the differential and not the whole rear-end... any reason that wouldn't work?

8.8 rearend diffs are the same from what i remember. get the hookup on a lsd from a explorer/mustang or somethin

Re: F150 Rear end question
 

Explorer is 31 spline and the Mustang is 28. Try to find one out of the same model truck for ease of installation. I would get a newer Sterling or a Dana 60.

Re: F150 Rear end question
 

yeah he doesnt need a rear end, he needs to replace his diff. possibly just the carrier bearings. take off the cover and look at it yourself.

Sweet guys thanks for the tips. Anyone have a 3.55 f150 diff they want to sell?

---- i used to, got rid of it 2mos ago

Re: F150 Rear end question
 

you could always rebuild the stocker....

it's not that hard and only requires a few extra tools

Re: F150 Rear end question
 

This suggests there might be wear on the ring gear and pinion, I.E. excess lash due to improper pinion depth.


I'd find a used rear end if it were my truck. Rebuilding a diff. is one thing, but you gotta re-shim and get the pinion depth/preload correct regardless. Lest it will just happen again in 15-25k miles.
