thanks for the info. the weird thing is i know people say the u-joints on the LMM(or any duramax) in general don't have grease fittings. well both the ones on my rear one piece aluminum driveshaft on my truck currently do and neither i or the original owner ever replaced them.
they seem perfectly fine but i just thought id replace them while i had the driveshaft out. guess i'll just change the yoke and reuse the u-joints.
I wouldn't bother replacing them, just regrease and go.
