true, but it all depends on what you do with your truck and mostly HOW you drive it.

Mine spends 99% of its time on the road sputtering around, but that other 1% of the time i bag the hell out of it and need it to be strong!

Other people might bag the hell out of their trucks on the pavement and need the strength rather than have the longevity of a greasable unit.

 

i would run the greasable ones regardless, unless it is a FULL TIME puller...if it is your DD that you like to hook to the sled every now and again then i would rather snap a U joint then breaking a yoke or gear set because the u joint was strong

 

yep i secound that as well, u-joints are a weak link for a reason
