TJ Manual hub question?

[jeepdreamer]

I guess it is not for everybody but I personally don't like things I can't grease and spinning the axles all the time bothers me.

I'm with you! Plus servicing the bearings is far cheaper and lasts a stupid-long amount of time! Unis... well, they last as long as they last.?. Not much comfort to me knowing they may be 10 years or 10 minutes away from failure! And its a good odds that when one goes, both need to be changed! Hello a couple hundred bucks worth of bill! Pah!
And as for getting muddy and disgruntled about locking hubs.?. Huh? You went to play in mud and got stuck...If you locked your hubs before heading onto the trail then you wouldn't have had to get a lil dirty. Or maybe stay away from mud?

I don't disagree with you, but there is an even simpler solution than the ones you propose:
Drive a Jeep.

I have access to Factory parts listings for TJ/LJ. The 2003, 2004, and 2005 have one part number for each knuckle. It does not appear to matter for a TJ/LJ if D30 or Rubi D44, same knuckle.

Excellent point above about the deleted T-case bearing. I have owned a variety of 4WD in the past each with manual hubs. I put many 1000s of miles on each of them, some 150K. I do like hubs.

One thing I have learned about the 2002 and 2005 Jeeps I own, once you start modding one item, there seems to be a waterfall of follow-on items, to support the first.

The other thing I learned a long time ago about hubs, lock em in early if going off-road. Very easy to move the T-case lever while on the move and keep momentum up. I have driven 400 miles on I'state with hubs locked in with a 99F350. No problems.

I AM interested in learning more about dumprat's design. Actual commitment will depend.

The Rubi and TJ/LJ are likely to have the same part number but its an oddball. One of the complaints (few that they are) is the strength of the Rubi Dana 44. It isn't a "true" 44 but a hybred which is why the parts interchange. If you put a rubi 44 next to a traditional (say, FSJ?) 44 you would instantly see the difference. And the JKs are even worse!

The TJ Rubicon Dana 44 has Dana 30 tubes, knuckles, wheel bearings, and brakes, etc. The only thing Dana 44 on that axle is the center differential housing itself.

It's a pretty good axle though. It would be great if it was high pinion. Supposedly South American XJs got a version with a high pinion differential.
