I replaced mine on Friday with a complete unit exchanged from Coloradodriveshaft.com (recommended on another forum). At first I thought I would just replace the center bearing myself, but upon further inspection of the 2 drive shafts I had, a professional rebuilt replacement was needed. Just jack up the rear as far as possible, have the 18mm socket and 18mm open end, a small prybar and the triple square socket for the diff end and you are good to go. There is great info avail at the above web site, especially about doing this without dropping the exhaust.
