8.6 reared noise

8.6 reared noise
I have a 99 1500 with an 8.6 reared. I had to do some work to the center section a while back. Cleaning, gears, and oil. Everything has been fine until recently. Now the rearend is howling. I believe it's outer bearings and my seals need to be replaced. Should I do inner and outer bearings or will it be safe replacing just the outer bearings?

When I had my 411s put in the races were scar'd pretty bad and I opted to replace them at that time.
I suspect the chunk is coming out again.

No I didn't replace the carrier bearings. They still looked good. It doesn't sound like the usual gear howling that I've had in the past. It sounds more like the roar from a hub assembly that is going out. I had my wife drive beside me and she couldn't hear anything. You only hear it in the cab.

I replaced the carrier bearings and one had a few pitted areas. The other side was fine. Found that it was my pinion bearing that was making all of the noise. So for anyone that reads the post. If you replace anything in the differential. Spend the extra 24.00 for races and bearings for the carrier and pinion. It might take a little longer but is worth the time.
