Yes, but 6cy (88-current) 8" r/p are a little different, but can still fit in a early housing with new bearings.


Just watch out for Tacoma/T100/Tundra 8.4" rear end, they do not work.

well its going in a 6cyl housing and into an early rear axle housing. so even if it was for a 4cyl it would be doable?

Complete 3rds are swappable with no problems as long as they are 8".

Let me get this straight. You have a V6 r/p in a V6 3rd member, and you want to put it in an earlier 4cy housing? No problem. I have my stock V6 rear end in the front of my truck which is a 85 solid axle.

Along a similar topic, are the v6 and 4cyl axle housings thw same?
I have a regeared E-locher 3rd I need to retrofit an axle housing for.
I've heard that the V6 and 4cyl aren't quite the same, with v6 requiring less modification... but cannot find confirmation of this anywhere... input?

Only major difference is the 1979-1985 axles are 3" narrower. Other than that, supposedly is only one little difference, the clearance from the diff to the back of the axle housing. Supposedly you dont have to clearance this area on a V6 housing, but I had to clearance it on my V6 housing. Maybe its only 1990 and newer housings? Either way, its just a very minor detail. 10 minutes of extra work to dent the backside of the housing. They are basically the same.

Ah, thanks for teh clarification. Sounds like it isn't worth any extra effort to find a v6 housing over the more common 4cyl. Good to know.

Standard 4-cylinder carrier has fewer spiders and is not as strong. The housing is slightly smaller. The R&Ps are different, and not as strong. Some have swapped I4 and V6 gears around with success, and the right bearings - can't help you there. The stud count and position are exactly the same as a V6 housing. Though it has fewer spiders, it is more robust looking than, say, a D30 in a Heep.

The V6 and elocker R&Ps are identical, the bearing sets differ only on the locker pawl side with the elocker.

I wouldn't say it is a waste of time to look for a V6 housing. The I4 housing with an ARB instead of the I4 carrier, however, is quite strong and a worthy diff.

The elocker diff in an earlier axle housing works fine, but of course the studs differ significantly and some cutting/welding is needed to make it right.

HTH,

That's actually what I was getting at. I'm prepping to do just this, install and E-locker into my '89 Rnr. The Q was whether to find a v6 axle housin gto modify for the studs, or just use the 4cyl housing that's on the truck now. Based on Adam's comments, it seems the effort to specifically acquire a v6 housing just isn't worth it.

I'm confused... the elocker IS a V6 housing with 'features'.

It needs a couple long studs installed in new locations on the housing and a couple short studs relocated. Use an elocker diff gasket to make placement easy, as far as welding up an extension to the mating surface. Then get a long drill or a punch the same diameter as the studs to dink the housing so you know where to drill, EXACTLY.
