I have had my '99 Wrangler for about 4 months. Just recently I have started to notice a humming type noise, I think it sounds like it coming from the right rear wheel area. I am assuming that the wheel bearing is going out.
I have been reading as much as I can find concerning the procedure to replace this component.
Axle = D35c
Is the bearing pressed onto the axle or into the axle housing? I keep reading about the need to have a shop press to instal the bearing.
I understand how to remove the axle, I have a couple of step-by-steps for that portion.
I am scheduled to replace my dif fluid soon and figure I could do this at the same time.
How do you tell if you need a new axle shaft?
Pics would be helpful.
I just replaced the bearings in mine a few months ago, they were in the axle housing not pressed on the axle.
I rented the slide hammer from autozone with the bearing puller and with a few whacks the old seal and bearing were out. Then I used the old bearing to tap the new bearing in place
What makes me suspect the wheel bearing is that I hear the noise only when I turn left at higher speeds, so in sweeping left turns and changing lanes fast or other instances when the forces are pushed to the right side.
I have a slide hammer that I bought when I was changing CV's on a FWD cadillac I used to own, so if that is all that is needed I think I can do it myself.
Is the carrier bearing the one that is in the dif case?
The bearings on the dana 35 are pressed into the axle housing. The dana 44 has the bearings pressed on the shaft. Since the dana 35 shaft rides on those bearings you may have worn bearing, a worn shaft or most likely both. You will be able to just look at the shaft and notice the groove marks or lack of grooves, but calipers or a micrometer will let you know for sure.

I am wondering if I should go ahead and get a new axle before I tear into her, I really don't like doing things twice.
I really only hear the hum in sweeping left turns, the exit ramp from the tollroad to hwy 290 is the turn that sets it off.
I guess there is no way to tell until I pull it.
I will see if I can source some axles locally in the event that I do need to replace it and order bearings for both sides.
Any suggestions on brand of bearings and axles. I used to order all of my parts from rockauto.com, any comments on the bearings they sell?
