Fj80 front differential help

[Charles Nordby]

So my front differential started making noise a few weeks back so I tore the front end apart and I am in the process of replacing all the bearing and seals while I have it apart but the issue im having is I got the wrong replacement dif. The guy I bought it from said it came out of an fj80 but the bolt pattern is completely different. On the bright side he said it wasn’t a locker but it appears to be. So now I am on the hunt for a different replacement. The question I have is what toyota suvs/pickups share the same dif as my land cruiser. Its an 8” 4.10. The other question I have is what kind of dif did this guy sell me so I can post it properly and get some of my money back out of it . Any help would be appreciated. I will attach a photo on the old (left) and new (right) difs

It could be a low pinion 8” out of a 1st gen

It's a locker type, you can see the shift fork groove. But from what? I'm no help there.
Why not just change the bearings on the gear set you have?
Its not difficult, a 12 ton press and a big bearing puller from Harbor Freight will get you there.

You'll also need a mag base and 1/2 thou indicator, but you can get inexpensive versions for less than a hundred bucks. Need them for checking various runouts anyway.

It is probably a rear locker from a Tacoma TRD, which has a 4.10 diff with an electric locker.
