broken ring gear

In the process of doing a routine diff fluid change, i uncovered what some may consider an issue.







Obviously this will need to be fixed at some point,, but as it is right now, the gears seem to be making decent enough contact that it should hold up for a little longer. So my big question is - how many more miles do you think i can get out of this before it becomes a bigger issue?

That's about as bad as a broken gear gets actually. I wouldn't say there is much contact there at all. You're trade off for time is metal eating up the bearings fairly rapidly as it's probably going to be pecking away at that pinion as it skips.

How many miles? I doubt many here would leave it in long enough to find out.

I agree with these guys, that's a time bomb. It could go at any moment and cause more grief than you have now. When they are engaged in the pinion you're only grabbing a little bit on the half broken one at certain points.

I got a Rear Dana 44 4:10 ring and pinion if you need it. Just pay for shipping and it's yours.

That needs to be fixed as soon as possible. If it were in our shop it would only leave with a new ring and pinion and new bearings or on a tow truck. It is not going to be long before you have a catastrophic failure. Do yourself a favor and get it fixed now before you are looking at replacing the entire housing due to a complete failure.

I had a front pinion bearing seize and it was a complete front end lock up. I can't imagine if I was doing more than 20 mph what would have happened. Be careful, and my offer is still open if you need them.

unfortunately i am running 5.13s. I've been driving the jeep a bit but i know its a ticking time bomb.

I guess i'll spend the money now to swap it out rather than waiting till the whole damn thing grenades.

Needless to say I was really surprised when i saw this. I know its 5.13s in a dana 30 but i've been running these gears for over 40,000 miles. Thought i had gotten past the point where they would break. Thought wrong.

Any vendors on here offering deals on gears as the holidays are coming up??

Pull the front shafts and drain the diff if you need to buy more time..
