Just looking for a general idea of what breaks the most. What I'd like is for you to list your tire size, 10 bolt or D44, what you've broken, and how many times.

Made-up example:

35" tires
D44
Locking hub (1)
RH outer axleshaft (1)
Axleshaft U-joint (2)

etc.

Thanks!

I've had it 4 years. I had 35's most of the time, and just broke the short side inner axle shaft (at the part that taper's). Both the seals needed replaced too, they were shot. I went ahead and replaced the ujoints too.

10 bolt
35" tires & lock right

Nothing yet. It will happen though. I carry wheel bearings, spindle, axleshafts, ujoints, locking hub, and yoke for it. I also have 4 sets of axleshaft for it just because I will probably need them someday.

I have seen D44's break

Dana 44 with Detroit Trutrac
4:56s with 35s
and now 4:10s with 38s

passenger side both ends after the u-joint broke.

I have seen lots of 10 bolts, D44s and other front diffs (AMC20s etc) break stuff, and 9 times out of 10, its the u-joint that lets go, then takes out the axle ears with it. If you are planning to upgrade, you have to do both axles and u-joints. In my opinion, Id leave the hubs so at least you have a relatively cheap easy replacement instead of gears or locker.
But thats just my thoughts.
Oh ya, and before anyone asks: I know I went the wrong way 4:56s with 35s to 4:10s with 38s. Reasoning was simple. I couldnt afford the 4:56s for the 14FF, so I swapped the front D44 to match the rear end until I could afford the gears... now I kinda really like the 4:10s, so the plan is to stick with them, and double the t-case or tranny. you know... before anyone asks... hehe.

Used to run a D44...

3.73 open
33" AT's
Big block /forums/images/graemlins/laugh.gif

Superwinch hubs- 2
Spider/side gears- 2 sets

Kinda wierd that the spider and side gers blew apart before the stub's or hubs at the time. Steering was at full lock to the left trying to climb a muddy hill with roots. Pretty decent amount of throttle. One little hop/bounce on the roots and they popped. Interesting noise too..BANG! popopopopopopopopop....lol, like a little machinegun. /forums/images/graemlins/histerical.gif
