I don't know anything about Tcase failure, but pulling with my front bumper was what I was doing when my front diff failed. After doing my research and discovering how small and really weak the d30 R&P is, coupled with the fact that the gears aren't designed to have the same stresses put on them in reverse than they are going forward, is what did mine in. I would be interested to know how or what is failing in the tcase if that is the case... haha, that reads funny. tcase if that is the case... It's easy to amuse me.

Unfortunately I can't find the link(s) now - I'll do a bit more searching. As I recall the driver was pulling someone out in reverse and his transfer case exploded. Someone thought the transfer case was weaker pulling in reverse, but I can't remember why. I just remembered that pulling in reverse is not a good idea, which I guess really is the bottom line.

Here are two links that have other reasons why pulling in reverse is not a good idea:

To be honest, because you describe it as an easy pull it doesn't sound like a weakness of the D30 in general so much as something specifically wrong in yours. I've pulled plenty of vehicles out without a problem. LOL: At least I hope no, because I'm putting a bunch of money into my D30 in hopes that it will continue to perform off-road as it has for the past 68K miles.

Newb looking for info...what is a D30 ? i know its like the axle and what not, but is it stock? Is a. stock JK ok to be pulling people out of ditch's with, obviously from the rear, and has anyone had any problems pulling with the stock hook in the back on the drivers side?

BTW i pulled out a F-450 Dually, Burried in the ditch... it was a bucket truck for a local company who fixes street lights.

Ok after getting a moment to look at it, turns out my driver side u-joint failed and my hobbling home did more damage. I will take a picture but it also looks like my axle is shot.

Thanks for the tip, but here is 2 pics to show how bad it is

EDIT:

2 Quick questions
1. Can I just upgrade to the Superior Axle on one side for now?
2. Any problems running the Superior Axle with the Dynatrac Ball joints I have?

I've been down that road a few times, easy fix. If you're going to hang on to your D30 I recommend picking up a SBS plug from Off Road Evolution, it beats stuffing rags in your axle housing when you need to pull an axle.

I also recommend fixing it your self. This is a great thing to know how to do on the trails, I've pulled quite a few axles out in the middle of nowhere which allowed us to get home at a reasonable time with no tow truck involved.

Thanks, you gave me the nudge I needed to order the axle shaft and do it myself.

I did the exact same thing about a year ago, snapped my driver side u-joint pulling out a disabled volvo from a snowbank

Check with your insurance. Sometimes they have plans that will allow you to have it flat bedded to the nearest shop for free or at least they may cover the hook up fee. Unless you know what you are looking at I wouldn't move it anymore.

Good Luck!
