Inner CAD bearing removal?

[jeepmjga]

Anyone bothered to do this?  I did the delete with a 97 shaft and everything and am getting a noise from that side of the axle that I think might be the shaft just barely contacting that inner bearing.  When I pulled the guts out of the pumpkin everything looked good as far as carrier bearings and everything else.  Just wondering which direction that bearing needs to come out.  Eventually will be swapping to a d30 with 4.10's but would like this noise to go away for the time being.

Are you referring to the really big bearing that holds the original inner axle near the CAD? If so, there is no need to remove it as it should be contact the new one piece shaft but it can be popped out in the direction of the CAD opening. I have used a long piece of metal tubing with the carrier removed to get it out. It shouldn’t be contacting a 27 spline axle shaft though.

Yea thats what I thought.  I guess I'll just open everything up and take another look at the carrier bearings and everything and see whats up.  Thanks for the info.

It’s easy for the drivetrain to transfer noise through various components. I had what sounded like a bad pinion bearing in the front axle. Turned out to be a bad transfer case front output pilot bearing that was making all the noise. Didn’t find it until after I had rebuilt my front diff.

Yea its been frustrating trying to track it down.  Got all new wheel bearings/hubs all around, new ujoints everywhere, and just swapped in an AX/231 combo, so I guess Ive got it narrowed down.  I can hear it somewhere in that pass side tube and in the carrier when I have the wheel off the ground and spinning it.  Guessing its gotta be the carrier bearings but they didn't appear to be in bad shape when I pulled everything.  On the hunt for a 30/35 set with factory 4.10's now.  Figure that is prob the cheapest/easiest option for get closer to proper gearing since I don't know squat about setting up new gears.  Its not 4.56s but better than the 3.07s I have now.

Update on this if anyone was curious.  Been hunting a driveline noise for a while and it did in fact turn out to be the new shaft just barely contacting the old inner cad bearing a little bit every revolution.  Finally got it removed and no more noise.

Awesome! Thanks for the follow up. Very helpful for future troubleshooting
