I bought a used pumpkin from a 2nd gen 4runner. 4.56 gears. I am currently trying to install into my friends 88 4runner.

I've done this a couple times before w/ not problems.I did the same thing to my 89 4runner.

This time, when everything went back together, the passenger axle isn't going in all the way. There's about a 1/4 inch of space between the backing plate and the axle. It feels like it's hitting something in the diff. axle is engaged w/ the gears and working, just seems like a large gap.

Drivers side went back in w/ no problem.

Any suggestions? I'm going to try tightening down the bolts to see if everything pulls together easily, but it seems like there's more of a gap then there should be.

cheers.

 

maybe you need one of these



haha

I dunno buddy, the other side's going in fine?

try pulling the axle shaft back out of engagment from the spider and turn it a little and try to slide it back in? I dunno... that's stange...

same old axle shafts, backing plates, and rear wheel bearings?

 

Only thing changed was the diff.

 

complete assymbled 3rd member swap, right? no fooling around with the gears? all stock gears? (by stock I mean stock for whatever Toyota the came out of... their not after market gears, no locker, or anything)

 

mine did the same thing on drivers, 2x4 block, and a mini sledge

 

I didn't see a locker. Gears should be stock toyota gears, but I didn't look that close.

I tightened the backing plate up and the gap closed up fine.

Looks like everything is good. I'll post to confirm everything's still good after a fluid fill and a test drive.

Thanks for reads and replies!

 

good to know!

let us know if all is well

 

the splines are just binding up, push it in as far as you can then thread the nuts on the back of the backing plate studs and tighten them a little at a time to pull it in straight. tell your buddy that he might have a bent axle housing if its getting stuck that bad, but if he hasn't noticed weird tire wear or vibration on that side its probably fine, my taco axles get stuck like that every once in a while.

 

It's usually nice to have a friend fiddle with the flange while you're stabbing the shafts. Shouldn't be too hard, might want to check out the bearings and see if the shaft is bent.

 

....carrier bearings could cause the shaft to misalign and not seat...

 

after tightening it up, does it turn?

 

i love it when my lady friend fiddles with the flange while i stab it with my shaft...



sorry swampy... couldnt resist...

 

I've had that happen to me before....it's just the bearing catching on the outer housing lip. Put the 4 backing plate nuts on and tighten them evenly and it will POP into place.

 

wow Troy... family safe man, family safe

 

LOL, thats how we got a family. Wrenching women are hhottt.

 

well I'm not denying that

I dunno though, some can be a little manly

 

IAM how's exhuast doing?

 

well, it sounds good, accept for a leak in that emessions tube that runs back behind the motor, lol

I'm not screw'n with it; all the emissions crap is going away on with the new motor I hope to start puting together very soon

 

That back plate is a PITA to get to.

 

that's why it's not getting screwed with
