Dreaded clunk when turning

If I remember right, I think there is a roll pin that needs to be driven out on that main center spider gear pin. Have to use a drift punch to get it started.

I may have used a 3/16 drill bit to drive that roll pin out because of the close fit.

Your new diff kit should have a new roll pin in it, look over your new parts.

Here is the tricky part, the large pin will slide easy when you get the roll pin out. But it slides up to one tooth on the ring gear.

So here is your choice, stuff a bunch rags in around the pumpkin gears to keep them protected, then take a die grinder/cut off wheel and grind a little bit off of that one ring gear tooth to gain clearance for the pin to come out. Polish a taper on that tooth so it does not wear the pinion gear when done.

I have done this ^^^.

Otherwise you have to pull the differential housing out to get the ringear and diff housing out, then you remove the ring gear on the bench, then the diff pin will slide right out. Lots more work . . .

It has been a while since I have been into one of these 7 1/4s, so see what you can figure out. Maybe you can find an expolded parts veiw of what you have.

Once in a while you will get into a rear end that has a small hex head bolt holding hat diff pin in, sometimes that hex head will have sheered off. See what you can figure out.

Good Luck
