Still Having Driveline Trouble, new(er) shaft in.

So I bought a shaft from a '95 cherokee and had it shortened. I'm down to 14.75" now because of the D44. I put it in and still get a bad knock like it's binding. Not a vibe, but a knock, and as slow as 5mph. The last shaft made the same noise, but the CV joint was toast and would only move side to side without binding, so I figured that was the culprit. The CV on the new shaft is in good shape, the driveline shop agreed as well. If I pull the shaft and drive in front wheel drive, it drives fine, so I know it's in the rear shaft. I've measured all the angles (several times) and don't see anything that should cause a problem. Maybe I'm just not calculating right or properly understanding how it should be set up. I've drawn a crappy pic to show my angles. This is really becoming a problem, and ruining my winter fun too! Please help!

Re: Still Having Driveline Trouble, new(er) shaft in.

Are you sure it's in the shaft. How about the pinion bearings or gear lash in the rear end. Seems to me like if you replace a part with another part, and the problem is still there, you've got the wrong part. How's the tranny mount and torque arm look. Could that be a contributing factor?

Re: Still Having Driveline Trouble, new(er) shaft in.

Found the problem, the ring and pinion are toast. I had discounted the rear end as being the problem, since it's from an '02 TJ and the gears only have about 15k miles on them. The ring gear has several teeth busted and the pinion is pretty chewed up. Hard to believe I ran the super 35 with a detroit that I set up myself for about 4 years, and wasn't easy on it, with no breakage. Then I put in an open 44 with professionaly set up 4.56's and get 1k miles before breaking it. [img]images/graemlins/chairfall.gif[/img] Here's a pic of one bad spot on the ring gear.

And another ring tooth gone.
These were Yukon gears setup by sweet swamp 4x4 here in KC.
Just an fyi.
