Save yourself time and money and keep the 30/35

I race my jeep and i built a 44 for it, still sitting on the stand that 35 hasn't broke anything, drag racing, road racing, oval racing... 400hp or 600hp....nothing hurts it...

Back from the dead!
I had forgotten about this thread until it showed up as I was searching for something else.

I mentioned that I ended up with a NON-C-clip Dana 44 from an '87 Wagoneer with 3.54 gears. Score!

Here's the axle cleaned up.

And then I dumped most of a can of gloss black epoxy spray paint from McMaster-Carr on it:

Separated the caliper brackets from the dust shields; somehow forgot to snap a "blasted" pic. I'll grab a "painted" pic in a couple of weeks after I get back from London. you can see the modded bolt patterns in both.

The original Dana 44 non-clip hub end component stack:

From left to right: backing collar (not sure why it's not touching the bearing...), bearing, seal, bearing retainer.

Modified stack: backing collar, new bearing, seal, spacer ring, bearing retainer

And the whole shebang installed, including brake caliper brackets and dust shields:

The left axle has pretty decent pitting on the seal surface and needs a speedy sleeve. If that hadn't been the case, I'd have put both together tonight.

The front end for this car is a Dana 30 IFS with 3.54 gears from a 4 cylinder Eagle that I rebuilt stock.

Here's using electrolysis to clean up a really munged up diff.

Here's the inside of the housing... haven't cleaned it yet and it's pretty nasty.

Was just a matter of cleaning it up in the parts washer

I've pretty much decided on an Eaton e-locker for the D44 rear and a Detroit True-Trac for the D30 front. I am hesitant to use a locker on the D30 front because it may cause me to frag axles... although the tiny Eagle front driveshaft is probably the first thing I'll turn into a pretzel or just snap.
