did a search but couldnt find this. ive got a77 f250 4x4 with a dana 60 rear in it. the u joint that attaches the the rear of the drive shaft where it meets the axle has no grease fittings on it.(or i cant find it) how do i grease this part? i think its been a while.

 

It is a non greasable u-joint, i would just replace both u joints.

 

thanks for the reply. ive never done this repair before but it doesnt seem too tough. any tricks to make it easier?

 

get a u-joint press. makes it a peice of cake job and reduces the chance of messing up the parts. also, with u-joints there are greasable and non-greasable... here is where you need to be honest with yourself and your driving. use greasable when you do alot of on road driving and will get under the truck often to grease it, and i mean often, like more than ever oil change i have found. also greasable u-joint seem to be weaker to off-road abuse, but may get longer road use. with non-greasable you may get less wear out of them but stronger off-road, but you can't grease them. with me to make my desision i bought two greasable and two non-greasable u-joints. all went into the rear driveshaft. first test i had one in the front part and the other in the rear, once i trashed those i put the other style in the rear and other in the front.

what i found was that the greasables had to be greased alot to keep crap out of them and the non-greasables had better seals. the non-greaseables have out lasted both greasables, one greasable broke 4wheeling and the other just plain wore out. i also found that the non-greasables last longer for me, and now i always use them now. this is also on my daily driver that i abuse off-road. like i said, you have to consider yourself and your driving style.

 

sorry it took me so long to reply, but thanks for the info. i think ill go with non greaseable

 

Another tip I learned (for both types) is to get as much of the crappy vasaline type grease that they come with out of there. Regrease it with some high quality stuff.

Dead right, the geasable ones come soaked in a rust inhibitor. This stuff is not a lubricant. If you clean the bearings thoroughly with brake part cleaner, then dry them before greasing, they will last twice as long. (Experience)
