Well it's time to replace one of my axles. Fluid is running down the side of the tire

I've already put a replacement bearing on both sides a couple years ago. They were pretty worn back then. Question is, what year of trucks can I steal a replacement out of? Prolly don't matter if it is 4x4 or not? I have the measurements 32.25 long 31 teeth.

Replacement Bearing ???

Did you try the "Repair Bearing Assemblies" rather than just new bearings.

They are about 20 bucks at most auto stores.

They alow for the bearings to ride on a different spot on the axel.

The oil seal is incorporated as part of the assembly and comes with it.

I love mine.

 

Repair Bearing Assemblies! That's the words I was thinking of. Yep. That's what I put on. I priced a new on, well that's why I'm gonna go to a junk yand and scavage hunt. I see a lot of early 80's f-150's in the junk yard, didn't know if they word work?

 

Ok, This must be a real hard question. Even the junk yards don't know. They just suggested buying a whole rear end and tear it apart. WTF? Anyone that could help me would be very appreciated!

I might as well play the lotto...

 

i think 87 up will work for ya

 

You might be able to go even earlier than 87...even a few prior toi those I've seen have had the 8.8's....but generally the 9 inch was run up until the end of 86......you sure it's not just a seal?Have you tried jacking the truck up and shaking the tire to see if you've got movement?If you can you oughta find an 8.8 rear out of an Exploder and convert it to disc brakes too......heh heh...Good luck.....I think I've got an 8.8 with 3.31's in a wrecked bronco........

 

Rock on!! Thanks a bunch ya guys for the info. All
I know, this is a 3.55, 8.8 (because I've done the math from inside). Since nobody puts the info tag back on when servicing it!

Flareside, I guess this is an assumption. Because I had such a hard time a couple of years ago with this. Good point though! I'll have to check that on out. Mostly I just wanted to check my options B4 I tear this apart. I'm hoping for the $2 seal !!!!

 

My advice is to tear it apart, and then decide what you need to replace.

Either a 9" from a 1980 or newer truck/Bronco or an 8.8" out of a truck/Bronco will drop right in. Note that some early 1980's F-100's without power brakes used a 5x5" lug pattern, which won't work for you. Measure carefully.

 

Dang andy I didn't know about the 5 on 5 thing....learnin something new...thanks

you cant use an explorer rear under a full size its too short and the bolt pattern is too small. 87-96 some 85 -86, i have heard of people using the 97+ rears underneath but yet to hear if and how it works.
