Uh, oh. Noticed this earlier this week. The first time I shift into gear (D or R)after the truck has been sitting for a longer period of time (overnight or while at work) I get a clank/clunk from the driveline. Sounds like a rear U-joint. It only does it that one time. It doesn't do it at shift points or at start/stops. It'll do it again after the truck sits for a long period of time. Whatttya think guys? Do I need to go see Eric? Thanks for any advise.
