rear Diff shop in C/S or CO?

[Skrimz]

So after a replacement of the rear pinion seal I noticed some vertical and outward play on the pinion, and some sweet vibrations when driving to work anytime above 50. I am not sure I am talented enough to reassemble the rear diff after I take it apart. I am guessing a bearing went bad.
does anyone know of a good shop in Colorado springs, or the surrounding area that can take a look at it and get it fixed up? I don't normally use shops around town so not sure where to go, and advice would be great. thanks

Check out colorado4x4.org, someone there should have a recommendation.
