Honestly, for me I'll just send mine off to get checked out and if it needs a rebuild, then I'm good. I know it needs to be balanced so that's at the top of the list.Man every time I see these posts it scares me to death. I bought my truck last year with 168k. It was fairly well taken care of, but who knows if that front driveshaft was ever lubed? I've heard of guys that lube their driveshaft and then it fails a couple days later...
Looks like you can get a full replacement driveshaft for ~$250 from some places... cheap insurance? Or is it better to just have the cardan joint rebuilt on the stock one? I don't have any vibration, but no peace of mind either
