Rear End Noise--- Poopy. Ideas Anyone? Hello,I have been abusive to my '02 Hawk with the stock 10 bolt. 
It has recently started to make a whirring or slight howling on decel. It also has this sound that seems like it has to be a tire rubbing because of the frequency- but it's not the tire. It has this shhhkk sound that take a bit of time for it to roll around to the next shhhkk sound. It is still a bit too fast for it to be a spot on the tire rolling around. I did some searches and haven't found an answer yet. Can I just replace the ring and pinion, or does this sound like a bearing and posi type of rebuild? Any ideas?

It is possible that you bent a tooth or two on the gear set. It does happen from time to time. They can be fine for a while, but after a few hard launches you get coast/decel noise. If you are going to be in there, do all the bearings while you are at it. A posi will rarely make noise in straight line driving, but it is not impossible.

Thanks for all the replies!!! 
The miles on the car 42k. I bought it a year ago when it had 39K. She sits in the garage most of the time, and when I do drive it- I don't baby it. This noise started a few weekends ago. It has gotten a bit louder 
and I know I will have to do something soon. A 12 bolt isn't in the cards right now so I will buy new gears from SLP and the related stuff and find a good shop in the area to do it right.

Are there any write ups on how to replace these things? I have a similar problem as you, firehawk, and found quite a bit of metal shavings/chunks in my gear oil today.

I have spoken to a few shops in my area and will most likely go out of state to More Performance to have them do the work for me. I didn't like the incomplete answers I was getting from the local boys. 
I would like to deal with a pro once than deal with ******** several times when there is a vibration or other junk happening to my ride. You might as well put some $$$ aside to get your 
differential repaired and better yet- buy a 12bolt! Good luck bro!
