Blown Rear Differentials & rear axle replacement

Arthur N Evelyn Lopez

Asked by Apr 28, 2016 at 09:34 PM about the 1983 Ford F-150 XL Standard Cab 4WD SB

Question type: Maintenance & Repair

I have a 1983 F150 XL v8 5.0 (auto) 4x4

I was driving and my rear diff blew to huge
holes in it, leaked all the fluid and left me
stuck. I used 4x4 to make it home and front
diff gave out. Towed it, rear passenger tire
along with bar that goes into axel still
attached fell off and left me sliding and
grinding. Will I be able to go get a new rear
axel and be good to drive in 2hi normally
again and fix front diff soon after? Would I
still be able to drive daily in 2hi? Or what do
you think needs to be repaired?

                                                    -Thank You

Since you mentioned a hole in the rear, you might need a new differential assembly, hard to diagnose from where I sit. Best to go to the junkyard and get one, also get a new front one from the same truck, gear ratio's need to match. a '83 F-!50? Lot of rust and miles? Might time for another truck.

So pick up the whole rear and front axles from another truck is what I am suggesting.
