D35 axle bearings

About a year and a half ago I bought an 88 XJ (4.0, Renix, BA-10/5, NP-231,
3.07 axles) with a lot of probs, but I thought, "it's cheap enough and
shouldn't cost a lot . . . . ."

Yeah, right. So far the cost is over $1500 not counting the purchase price.

I replaced the bearings on the D-35 rear axle because of excessive play ...
a full 1/4" up, down, back, front, in and out.

Pulling the cover (which was tagged "Tru-Trac), I find an open diff and
axles without C-clips. Books said there should be C-clips. ?????

Pressed on new bearings with the skinny little retainer ring to the flange
side like the picture in the Chilton's ( or was it the Haynes?) showed after
bashing the retainer plates flat ( both were bowed a bit) and turning them
over to put any remaining bulge inward and thus holding the bearing tighter
(did all seals at the same time).

Now it's 5000 miles later and the bearings have the freeplay back: 1/4" on
the right and a little less on the left.

What did I do wrong or is the axle another item that's been screwed up by a
doofus (the PO or their "mechanic") that should nor be allowed in the same
universe as a toolbox?

Got me. I just putter about, never done a diff except to change fluid.

Tru-Trac is a limited slip diff. Here is a pic of the unit.

Thanks, Doug, but unlike many XJ owners, I'm not interested in rockcrawling,
just putting about town and out to the fishing hole, so axle upgrades aren't
my cup of tea.

This is my first Jeep since the M-38's I drove in the National Guard before
my unit got the M-151-A1 and A2.

I've seen pics of limited slips including the True-Trac ( AMC/Eaton system)
and mine's an open diff.

I've got my mitts greasy on many differentials from riding mower Peerless
units and Mopar 7 1/4" to Yale-Towne 17" forklift ... took a forklift to
pull the pumpkin on that one!

C-clip axles are supposed to have C-clips but these shafts didn't even have
the grooves for the clips, so you can see why I'm thinking somethings not
right.

BTW, if I had my choice, I'd swap the Renix 4.0 and BA10/5 for a 225 Slant
Six, Loadflite ( truck Torqueflite) and a full / part time T-case in a heart
beat, but I don't think the recess in the firewall will allow for the tilt
of the engine.

Well, I guess no one here can offer any help.

So as soon as I can find another ride, this XJ is going to the crusher.

I won't risk my life or my wife's in a vehicle with a bad axle design.

Hmm according to this the XJ didn't use Cclips until '90.

My Haynes and Chilton manuals say that too, but that doesn't help me figure
out why my rear axles shafts are trying to go in directions the XJ isn't
heading. Sumptin ain't right, folks.

My old 64 Valiant with the Chrysler 7.25 axle used plates to retain the axle
bearings also, but the bearings were pressed on with the cone toward the
diff and the bearing cup was retained by the plate through the seal.

Any vertical load was directed inward, pushing the axle farther in.

On the D-35, the bearing faces the opposite way, if I see the diagram in the
repair manual correctly, and the vertical loads force the axle outward,
against the welded (???) to the cup assembly ring, then the outer seal, then
the retaining plate.

I replaced both bearings not 5000 miles ago and the old ones were in the
same position as the diagram ... and both the welded retainer rings were
broken loose from the cups.

If this is the way it was designed, then some engineer had his head in a
place where the sun doesn't shine and his brain died from lack of solar
radiation. It's absolutely stupid to design a bearing installation so it
tries to disassemble itself while in service.

But that's just my own honest and terrified opinion.

I've contacted A Jeep dealership to check on a TSB about the bearing problem
and Timken to see if they have any ideas on the situation.

I've heard back from my friend at the Ohio dealership and he went thru all
the TSB's including the ones they got from AMC / Jeep dealerships and found
nothing. He then checked Alldata on it and found nothing, so it looks like
my axle's got a problem thanks to the guy that was too cheap to buy a truck
.... the previous owner.

I've also heard from Timken and Monday I'll be calling their 800 number to
talk to a representative about the issue.

Next: Dana Corp.

Thanks for the reply but please don't slam Ma Mopar. The second best offroad
vehicle in WWII was the Dodge PowerWagon ... the only thing besides a
tracked vehicle that could go most of the places the MB could go.

You're not the only one having problems with D35 bearings.
Mine's gone twice and this time I need a new one.
I've got the odd 3.73 size that's only on 4 banger automatics...

A Timken Bearing Corp. rep requested I check for damage to the outer seal
and for a bent axle housing. I measured 0.035" in-out play in the bearing
(supposed to be 0.007" - 0.010").

Seal checked fine but I think the problem I have is in the retaining plates
that hold the axle shaft in. Mine are heavily scored and I forgot to turn
the right side axle plate over on the last install.

No biggie. New bearings, seals from local parts stores and new plates from
www.4wd.com going in. Then I begin checking every week for looseness and
shopping for a older Dodge compact (pre-75) or truck (pre-80) or Plymouth
compact (pre-75).

I'm fed up with computerized vehicles and cruddy Dana axles. As soon as I
get something without either, this XJ is gone.
