...but, if you don't want to spend on a rebuild or replacement, can you just slip a needle fitting on your grease gun into the u-joint and pump in some moly grease??

Thanks Dusty!

Anybody know what centering ball BPU uses in their shafts?

I have a busted up failed bpu unit on my shop floor. I can look tonight and see if it has any visible stamping

it is the heaviest duty one that they offer.....centering ball imploded and it was still full of grease. pulled it apart and center spring was not present.....so it be a guess as to why it failed......@ less than 10k miles

I installed my BPU shaft at 90,225mi - at 96,240mi the CB almost gave out. Shop told me there was no grease in it. Now, would 6000mi do this? I'm not sure, but there ya go...

Hence the reason I really want to inject more grease in there. I'm at 101K now.

well my only hope is the quality control was better before BPUtah starting selling them... haha i bought mine on ebay from "Tatton" drive line shop in SLC... now sold by BPUtah i believe. shafts on their website look exactly the same as the one i got a few years back

I haven't had any issues with it... yet...
