Maybe Troy can be showing those steps on your rig to some of the group while i'm showing others the same steps on DJ's.

Nope, sorry. #1 - I gotta learn the gear install part, never done them and really need this knowledge. #2 - I ain't gonna be the one squat down to work on Terri's rig with this bum knee of mine. :D
 
The D44 that was brought up originally was one that DJ had that would be finished, just needed installed. He was going to install it while the front was being done - pretty simple swap of the whole axle unit, nothing involving gears.

Sounds like there's enough going on with the full front rebuild and MMIXJ's front ball joints happening in the background.

Bounce it off Terry, but I imagine he'll have his hands full for a good portion of the afternoon.

Again, the intention of the "tech seminar" is for several people to get together in a class setting and learn, not so much hands on. If there's interest in having a group 'wrenching day where everyone brings their projects to one location and those that don't have a project come and help, I'm all for discussing that as a future event, but that would require a VERY understanding shop owner and/or tradesman to have that much free work and experience being delt out.
 
I think you're right Troy, we have our hands full for this event.

Don't feel like this is your only chance to get your axle rebuilds done or to get help doing your own.

I think most everybody will get a good working knowledge and feel alot better about tackling a D30 or the very similar D35 and D44 rebuild themselves.

And there seems to be several willing, experienced people willing to lend a hand to a member that may need it.

We can also do some video taping of this event and make tapes available to NAXJA members.

NO thats fine I might have not said that right. I thought it was to do a d44 gear swap. I thought you were going to try and do it with the axle under the jeep and I thought what a PITA you know. Now it sounds like your just pulling an axle out and swapping it with another axle I take it, So this isn't a gear swap install tech thing going on just parts swap then?

I'm looking at learning how to do gears at this point. Need to do them on the D44 and HPD30 I got. I have the gears and install kits, but want to walk through with someone on how to set them up the right way.

I'm not looking at other people doing my work for me. Looking at learning how to do the gear setup myself. Sorry if it is coming across that way.

no, it is a "gear swap install tech thing"... on the front axle. DJ was also thinking about throwing the 44 under the rear since it is a simple swap.

basically a front-end tear down on both jeeps-- then gears, etc on DJ's and ball joints on mine.

should be great fun and an awesome learning op (thanks terry).

That's correct. DJ's axle will be torn down to nothing but the housing. New gears, new locker, new bearings, new seals, new alloy axle shafts and HD u-joints of some sort, and the R&R of the brakes and unit bearings. The only thing NOT being done on DJ's rig are the ball joints...... That's where MMIXJ's rig comes in.

Definitely a comprehensive look at the repair and modification of the D30. Plus, DJ's rig has custom high-steer and the over-axle track bar bracket mod already done so many of you will probably be interested in seeing what a lifted XJ with correct front geometry looks like.
 
Ok cool thanks thats clear sorry guys I'm on my fifth monday this week. So ready to go home and crash after a few drinks.
 
must be the anesthesia

DJ just called me from the hospital, and he said to go ahead and put those alloy shafts in my front end... :callme:

really. no need to call him and verify.
:eeks1:
 
Dude, I say we sell the locker, gears, alloys and new unit bearings to the highest bidder at the seminar and give it back to him with a hollow D30 and stubs holding the old unit bearings in place...... :D

Or, better yet, let's just sit around drinking beer and just tell him we did all the swap stuff........:gag:

I like your thinking, when I had the Tru-Trac in my D30, you couldn't tell any difference in the drivability. Unfortunately this was true on the trail too.

So...if it was left out......... hum.
 
massive thanks to terry for a very educational afternoon (and evening). ;)

...and don't believe anything you hear about any alleged ball joint installation gone awry; no pix, no proof.

:cheers:
 
It was a long day but good to have some of the guys out and take some of the mystery out of gear install.

Nice to meet everyone!!

We did struggle with getting the gear set-up to come out right.

I think the biggest problem we had is that the set of shims that came with the master kit, did not have any .001 shims in it.

So when we tried to do small changes to the set-ups we would swap with a few different thicker shims in an attempt to make small changes.

Like for instance if a shim pack had a .006 and a .008 and a .010 and a .020 in it. We could take out the .010 and add a .008 for a total change of .002.

But it seems like we kept having to much of a change with those type shim swaps.

I finally got out the box of Dana 44 shims that I had left over from several installs, and it had the same size carrier shims, and several were .001

I think we had the pinion in and out about 5 times before the depth and the bearing pre-load were good.

The carrier was much harder to get good backlash. We must of had it in and out at least a dozen times before I finally dug out those D44 .001 shims. Then we got good backlash and bearing pre-load on it, and then we were finally able take off the set-up bearings and press on the new bearings.

One of the harder set-ups i've had to do. Glad it wasn't out on the trail.

Thanks for coming out everyone and I hope it was educational.


Note to self: watch the other installs going on in the shop a little closer, just in case someone were to install a ball joint upside down and then have to knock it back out.

just to clarify (ahem), the ball joint in question was not installed upside down, but rather just pressed in from the wrong direction :doh:
(up from bottom of ear, instead of down from top). :confused1

thanks again terry, the timing was perfect!


...though i guess i've been spending too much time w/ mountain bikers, 'cuz i apparently brought too much beer. ;)
:cheers:

well, the fact I understood your post means ya did a good job :cheers: Thanks to those that put this together. I got more knowledge in 3 hours then I have over 3 years and 10,000 locker/ls type threads.
