Anybody in or around Charlotte, NC know of a good trustworthy shop to do work on my rear diff?

I have an 03 Screw 2wd with 180k miles. It's had a relatively loud "hum" at any speed since I got it about a year ago, recently (a month or so), i've been getting the take-off grind. I figure its time. I'd like to do the work, but I don't really have the time.

Any help is appreciated.

Thanks!

 

Oriellys sells a kit with all of the bearings and seals for 100 bucks. I have to do mine also.
