Rear end options
Okay, think I finally got my brakes working correctly, and have been trying to put some miles on the truck to see what else is wrong. Last night I picked up a vibration towards the rear of the truck. I haven't had a chance to track it down yet, but I'm thinking it's either the differential going, or something along the 2 piece driveshaft, probably the carrier bearing.
The reason I think it might be the diff is that when I redid my rear brakes, it appeared that the bearing around the axel was leaking since I had tons of heavy grease in my drum, and the diff housing was low. I filled it up, but didn't have a chance to check it last night. Currently has the 12 bolt corp axle, believe it's the HO-52, but haven't confirmed that yet. If it is the diff, what would be the pros and cons of either rebuilding this one, or replacing it with another one? Also, can this one be converted to either a positrac setup, or a locker setup since if I do rebuild it, I'll have it apart anyways? Thanks! Scott

An HO52 is a full-floater used on 3/4 tons. 10-bolt cover.
That bearing does not seal prevent oil from entering the drum. There should be a seal to the outboard of the bearing sitting inside the very end of the tube. That will allow oil into the drum. Before you pull your cover and look for metal shavings, discolored teeth, nasty oil, chewed up teeth, etc, make sure you have all the weights on your prop shafts. Mud will also throw your driveline out of whack, as will a defective carrier bearing (which you already mentioned). U-joints are also a highly likely suspect. You can convert it to posi or locker setup, but certain posis & lockers require different carriers than what you have. Someone else on the board can pick this up since I'm not all that familiar with 12-bolt carriers.

Thanks, and sorry for my confusion. Thought the HO-52 was a 12-bolt. Anyways, planning on checking my driveshaft and u-joints tonight, and trying to get a new carrier bearing ordered to be on the safe side.
Anyone have any experience with Powertrax LockRight units in a 12-bolt? Thanks, Scott

What do your tires look like? You tried rotating them?

They look okay. Haven't tried rotating them yet. I might try that before the driveshaft work tonight.
