Passenger Side Axle Bearing

[robbie95]

thats what happened when I tried to chisel it out.

[yxmj]

Yes.....hence the tap it first to see if it separated.... Looks like we jumped right to smack.....the burr can be cleaned with a file or a dremel

 

Can you lay your new bearing face down out of the package beside your old the same way...it may be the camera.... But in your other pic it looks different?

 

And fyi....you can post pics right on the site

one on the left is new, right is old. "new" meaning the new one I messed up trying to install it.

Edit : Maybe I just need a bigger hammer and a little more elbow grease? I chipped off a little bit of the metal on the new bearing trying to install it yesterday, don't know if that was an error on my part or what..

If you want to use a cheap replacement rear axle bearing (Mopar p/n J8134586) from Advance for your 91 D35 c-clip rear axle, the correct bearing is Driveworks S-5707. A better choice is National bearing #5707, also available, and I believe it comes with a new race. 

[robbie95]

yea, it isn't budging, could I use a dremel and just grind that lip down? that's whats holding it from going any further back

[robbie95]

 

It has to go in more than this, right?

[HOrnbrod]

Supposed to be flush with the axle tube end.

i'm probably just gonna be done with it and send it up to the mechanic, can i push it without a axle bearing?

Can you get the c-clip back on as-is? If so, then yes.

so by "should have come as part of the new bearing" you mean the bearing and race are 1 piece? not 2 seperate pieces? if not, I can't seem to find a new bearing race on the parts list.. and yes, what I removed looks exactly like the new bearing I have.. nothing seemed to break apart or anything..

 

The C-clip Dana 35s are different from the ones I have, and seem to be the opposite. With mine (non-C-clip) the only thing to be pressed into the axle tube is the tapered race. The roller bearing is pressed onto the axle shaft itself.

 

Apparently the C-clip axles have the outer race and bearing all together, and that's all pressed into the axle tube as an assembly. There doesn't appear to be a separate outer race. The rollers appear (I guess) to roll directly on the axle shaft. So the question is, is the outer diameter of what you removed the same as the outer diameter of the new bearing assembly? If so, it should go right in, and it may just be your technique that's the problem. If the old and new assemblies appear to be the same, then you shouldn't have to remove anything.

 

That inner bit that you started to chip away at -- in your first set of photos, that looked shiny and slightly tapered, which is why I thought it might be a race (along with the fact that I'm accustomed to working on axles that have a race there). Check it out -- is it tapered, or are the walls straight and parallel? Don't do any more chiseling until you know for certain if that has to come out, or if it should stay.

 

Don't go by the video of the Dana 44 -- that uses a separate bearing race, not an assembly.

If you put the axle back in without a bearing, you'll scare the shaft and ruin it. 

 

Did the original bearing come out in one piece? or many pieces? 

 

If many pieces, that is the original race of the bearing that is left in the tube.

As-is, with the bearing it's okay.

 

Seems the OP got a lot of unintentional  bum dope in this post....

FSM doesn't offer much useful information. No exploded diagram.

They aren't the same. Do they look the same if you flip one of them over?

 

Why is the new one missing three rollers? (And why is the old one missing one roller?)

I mentioned the "original" the first one you took out... show that beside the new

it's raining pretty bad so I'll have to see if I can when it stops raining. If not, I guess I'll have to tow it there.

this is what every part store has given me.. it's missing rollers because I broke it trying to get it in there the first time (it was bad technique) and idk why the old one is missing one..

that is a side by side comparison, i just broke the new one. 3 rollers fell out after i smacked it a couple times.

[Jeep Driver]

Whatever remnant is in that tube, it's got to come out. 

 

There is no stop in the tube.

No my friend....not the new one that you broke....not a new one at all....where is the one that came with the truck.....the first one that was in the truck originally....the first one you took out....when this all started you took a bearing out....show a pic of that original bearing

And be sure they are oriented the same. In the first photo where you showed two bearings side-by-side, it looks like one was facing the camera and one was facing away. They definitely did NOT look the same.

D35 axles have their bearing rollers ride directly on the axle shaft, and the axle functions as the "inner race" for the bearing.

 

The outer race for the bearing is a LIGHT press fit into the bore of the axle housing.  A block of wood and a few taps are all that it should take.   Anything more than that, and something is wrong.  Either the bearing is the wrong size, or something is inhibiting the bearing from seating in the bore of the axle tube.

 

There is a change in bore diameter in the axle tube that acts as a stop to prevent the bearing from being driven too deep. 

 

The seal for the axle shaft is a slightly tighter fit into the axle tube.  It is coated with a colored sealant on it's outer surface, and thus needs to be driven into the bore of the axle tube with a block of wood and a dead blow mallet until it is FLUSH with the end of the tube.  If the seal won't seat flush with the end of the tube, you have not got the bearing seated into the axle tube sufficiently.

 

By the way, check the surface on the axle shaft where the bearing rollers ride.  If the shaft is scored, heat damaged, or exhibits spalling, the shaft must be replaced, or the axle will trash the new bearing in short order.

Don't feel bad because you perhaps buggered up a job on your MJ. Everyone here has done the same, it's p/o the learning process. I strongly suggest you invest in a set of Factory Service Manuals (FSM's) for your 1991. It's the best tool you will ever own. I've had my 91 for many years and I always learn something from every job. Used FSM sets can be found used on Ebay for not much money.

I appreciate it man, yea, as frustrating as it gets sometimes, I still love to learn how to work on my truck.. everyone tells me to get rid of it, but I can't... I love it lol.. I'll have to look into ordering one of those.. would probably make things a lot easier..

The one on the right in the picture I posted is the original one that I pulled out of the axle tube.

Yea, that's what I've been thinking the whole time, I wish I had something to measure the diameter of the axle tube, then measure the bearing I was gonna install, but I don't.

You don't have a caliper? They're cheap at Harbor Freight Tools. Just get a dial caliper and learn to read it -- skip the digitals, they eat batteries. Measure the bearing you took out, and the one you got from the store. Does the one you took out look like there's an outer shell that's missing (as in, it got left in the axle)?

 

Show us a 3/4 edge view of both -- oriented the same way.
