Stuck cross pin. Please help!

[19Walt93]

In 42 years at the dealer I never saw a ring gear need to be ground to remove the cross shaft. That ring gear looks way thicker than I would expect to see, I'm interested to see what your ratio is.

So I just counted. There was 41 ring gear teeth and 11 pinion teeth. Divided it and it was 3.7. Which is right, right?

that situation does exist. need a small chip from 1 tooth removed. I think it was a 4.10

Does anybody know of anybody in the Kansas area that can do body work on my 1984 ranger for a decent price

don't have to grind much. this is a 4.10 7.5

I've never seen that. Maybe I didn't encounter a 7.5 with limited slip. If you grind it, please chamfer the edges a little.

while using a mini grinder I repeatedly slid the cross pin out to check progress.
the end result was only a couple thousandths clearance. not even close to the contact area.
I usually dress the edges of things, definitely a good idea.
this is an open diff, I'm reasonably certain the dimensions are the same for Traction Lock.

Wrong thread. Be better ti start another

I thought the whole reason for the stepped cross pin as seen here was so that you didn't have to grind the gear... Instead you slid the pin out as far as it would go, which was enough to allow you to remove the axle C-clips. Am I not remembering this right? (it's been forever since I've looked at one with such a pin).

That said, I would grind & replace with a solid pin because the solid pin is stronger (and is also required for most lunchbox style lockers).

 

[Mechrick]

You rotate the cross pin 90 degrees, which allows the axle to move in to the flat ground in the pin just far enough to remove the C clip. Then rotate it 180 degrees to remove the opposite axle. When installing a ground pin you have to slide the pin into the carrier, then bolt the ring gear on.

As far as I know, you can't install a lunchbox locker in a limited slip carrier.

With really big gears (5.28, etc.), grinding the gear is no longer an option.

Yes, to get the cross pin out of a 4.10 carrier you have to grind a tooth or do as Mechrick explained above which is how the stock notched crosspins are supposed to work. I ground a tooth on my 8.8 with the 5.13's and it's still not in the wear surface...

There's no lunchbox lockers for the limited slip carriers that I know of so you'd have to change the whole carrier. On my '00 Explorer I just said screw it and welded the limited slip diff solid, not recommended but so far so good...
