so I went to cange my rear end oil and take a look at the rear end cause it was makin a little noise....so I pulled off the back plate of my 8.8 and to my suprise i found about a 1 and 3/4 inch fawkin chunk of my pinion gear shaft........it just looks like it slid out a bit and sheered it off but it still works but I'm not gonna test it..... so now I have a front weel drive bronco fer now cause I'm takin a mechanics course but my cocksuckin teacher wont let me fix it!!!! I"M pissed!!!! is it alot of werk to change the shaft? or should I just through in my 9 inch that i got in one of my other bronco's? wat would the gears be in my 89 bronco with a auto tranny and a 302? PLEASE HELP

go to the door tag and get the axle code, post it up here or search it up on google. It will tell you what the gears are.

I'd say get a 9" and the TTB centersection from an older Bronco (Same truck) and go nuts.

it is a little late to change the fluid after it has started making noises

no I just heard noises today thats the only time i heard noises also just wonder if it would be quicker to just swap the 8.8 to my 9 inch and get the gears from the front end of my other bronc then to change the pinion gear shaft in the 8.8

I'd go with the 9" - better axle IMO. Kinda nice to diff maintenance & upgrades at a workbench than laying under your truck the whole time.

You don't need matching ratios to get RWD back. ;)

You mean pinion gear or crosspin? :confused:

Crosspin is easy fix. Get another one. FWIW, I blew the spiders and crosspin out through the cover of a 12-bolt Chev. Replaced the spiders & pin, welded the hole in the cover shut. Still hasn't blown up. :D

Pinion shaft means new gearset & setup.... then I'd say 9" it.

I'd definitely go with the 9" as an upgrade replacement to the 8.8 I went thru 3 8.8's in two years and most of the driving was highway! 2 outta 3 of those times it was the crosspin, the 3rd time the carrier actually broke... junk! If you are really lucky you might be able to find a half ton D60 rear with the 5x5.5 pattern... i have one out of an 80's ex-railroad fleet truck thats going in my '76 2wd eventually.:cool:
