Stuck birfield / oil seal questions (1 Viewer)

[reddingcruiser]

Assuming it's a stock, open diff (or not), the axle shafts engage the side gears which sends the rotation of the ring and pinion out to the wheels. It seems the general consensus is your axle splines are twisted or otherwise bound up in the side gear. I would be surprised if an 8mm bolt will be enough to do the job. It's unusual for the twist to occur inboard of the side gear, but if twist is severe enough there may be too much pressure on the splines for them to slide in or out.
If drilling and tapping for a bolt doesn't work you may end up welding on something more substantial for a better bite, and some hydraulic help. Worst case will require some invasive surgery.

Out of curiosity, stock 2F engine?

yep, stock everything as far as I know.

do you still have the roughly 1/2" in/out play on the shaft?

 

[OhioFJ]

Yes. I’m currently trying to bust out the oil seal

Busted out the seal and got a little more play

 

[OhioFJ]

YES

vice grip on the end and hook attachment on slap hammer did it.

now time to get it cleaned up to see what the problem is..

Nothing like the satisfaction of victory! Congratulations.

How about a close up of the splines.

 

[OhioFJ]

Surprisingly they look ok? The photos are take 180deg apart. Further investigation required. I'm going to clean everything up and take a look.

Looks like your lucky day. For the price of a diff gasket you may want to pull the third member and give it a look. You're 95% there now.

seemed really strange that you appeared to get 1-2 inches of additional in-out play (out at least) when you removed the axle seal. Almost like it wasn't binding on the inner splines (which are only like 1-1.25" long)? And now they look fine once it's out? I'd definitely pop the diff out to get a look at the side gear insides

 

[OhioFJ]

Yeah I'm not sure whats going on yet.. The axle really wanted to bind against the front-side of the seal at the knuckle. The housing doesn't look bent enough to have caused the problem; just looking inside I do not see any gross deformation. Will post updates.

X2 on pulling the diff

I think its something in the diff.. I can pass the axle smoothly in the axle housing until it meets the side gear in the diff. As it engages the whole axle is being forced forward. This must have put excess pressure on the inner oil seal, causing it fail. Story is not over but it's interesting to figure out why things fail.

any odd tire wear?

 

[OhioFJ]

no, not that I have noticed.

 

[OhioFJ]

Pulled the diff. Overall looks ok to my untrained eye. Will keep looking.

Ignore me mist some of the thread

Did ya roll the inner axle on a flat surface to see if its bent?
