Thanks for the replies fellas. The truck is a 4x4 and and was towed approximately 90k. Which is sounds like could mean replacing the tranny or t-case in the near future, but then again not that much wear on the rest of the drive train. I may go take another look at it tomorrow and see about doing a compression test. Any ideas on how to check out the tranny/t-case for wear other that just general feel while driving? Thanks again.
