Hello All,

I came across this rear slip diff for an 8.8 rear end on a ford. It looks to be in good condition and he only wants $50 for it. What do you guys think? Should I jump on it?

 

28 or 31 spline and what do you have?

 

i would still replace the clutches and plates in it......then for $100 you have a brand new diff...

 

Well I got the 8.8 off an 04' Ranger Edge. I believe it's 28 but I could be wrong, it might be 31 :( I'm about to get my new gears installed into the 8.8 and I wanted to buy this too since it's such a bargain but I don't know if it's in good condition or not.

I think I might be able to talk this guy down to $25, cus something tells me this rear slip diff isn't in working order right now since he's selling so cheap..

 

How hard is it to rebuild a diff? I'll probably get it done professionally if it's something I can't handle.

 

it is super easy......pretty much self explainatory....

you have a 28 spline diff...

 

I need auto mechanics for dummies :( lol

Any tutorials?

 

So what is the one you're buying? If it's out of an Explorer or F-150 it's a 31 spline.

 

I'm going to call the guy right now and ask him.

I'll update you guys shortly.

 

Alright I called the guy and he said it's an 8.8 out of an F150 and it's still in good condition. He said I shouldn't need to rebuild it. He has a 9' rear end now and that's why he took this out of his old 8.8 when he changed it to sell it.

So I'm guessin it's 31' spline? And my 8.8 is 28?

Will it still work?

 

no it will not work....your 8.8 is a 28 spline and the Explorer and F-150 8.8's are 31 spline......

you have 2 options:
1. keep looking...
2. buy aftermarket 31 spline axle shafts for your 8.8 (roughly $250 each)

 

Ouch that's rough.

I'll keep looking. Thanks !

 

You should buy it anyway, then sell it for more.
