More newbie axle questions

Okay, more (hopefully not stupid) newbie axle questions. Since the consensus is that D35's are weak, it looks like at some point I'll be upgrading my axles. I have no experience with welding/re-gearing, etc. So, given the labor costs of fitting a scrounged D44 under my YJ, would I be better off $-wise scrounging & fitting or buying a new 'custom' axle? Ford 8.8 swap?

Re: More newbie axle questions

8.8-8.8-8.8 I can't say it enough. You can get one in a junkyard with 4.10s and disc brakes for 2-300$ and the mounting kit is available from MORE for $140 and it includes new perches,spring plates, u bolts, and shock mounts. All that is left is a yoke for the rear u-joint which they also have or any driveshaft shop should have. If later you decide to upgrade your transfer case with a slip yoke eliminator you can get one that uses 1330 u-joints instead of the stock puny 1310 and there is also a yoke available for the 8.8 that accepts it.

Re: More newbie axle questions

Jimmy, do you know the cap diameter for the 1330 u-joint? I want to check if that's what I got by accident. (I can hope, can't I? [img]/wwwthreads_images/icons/smile.gif[/img])

Re: More newbie axle questions

The 1310 and 1330 cap diameters are the same, but the cap to cap length is greater on the 1330 (3 7/32" for the 1310 and 3 5/8" for the 1330).

The 1310 is good for 1,600 ft-lbs of torque while the 1330 is good for 1,850 ft-lbs, so the 1330 is only 15.6% stronger, not a huge difference.

Re: More newbie axle questions

besides the 8.8, another easy good swap is the dana 44's that came in some cherokees, same width and bolt pattern, (finding one is the hard part, i buy everyone i can find [img]/wwwthreads_images/icons/smile.gif[/img])

Re: More newbie axle questions

Jeepn...15% is better than nothing, and if they hold up to V8s in full size rigs(OK only half ton but)they're better than what the jeep came with. By the way, where did you find the tourque rating? Info like that will always come in handy.

Re: More newbie axle questions

No kidding, sometimes 15% is the difference between riding and walking, and I was surprised on the stats as well, I also thought it'd be more.

I have a vast amount of reference books on the shelf, actually a few shelves, but that particular piece of info I got out of the "4x4 Jeep Performance Handbook" by Jim Allen, which is awesome reading.

Re: More newbie axle questions

Thanks, guys. Jeepn, I think that's the book I read about the different kind of lubricants/greases that are not to be used together. It was a rental so I don't have it any more. Do you guys have that info?
