I had my Front U-joints replaced with servicable U-joints last summer and have had my oil and U joints serviced at Jiffy Lube because I can watch em kinda. I allways ask did you get all three of the U joints and they say yes and I pay more for this by the way!! Well I was under the truck today and noticed one of the joints was backwards I cant get my grease gun on it!
I might go to jail tomarrow it was good know you all talk to in 5-10! : / I am going to get $$ back and this fixed for shure!!!
So the point of this is go look at yours you may have a servicable unservicable U-joint err somthing like that!

 

thanks for the tip, I'll check mine out

 

Forgive me for being stupid ?? but.............How can it be backwards ? its not possible

 

I use u-joints with the zerk in the end cap, but I could see how some u-joints with the zerk coming out of the center at an angle could be put in so the center yoke of the DC would make it hard to lube.

 

DITTO on the joint being installed so that the grease zerk is at a bad angle and can't accept the grease gun.....I hate to admit it but I made the mistake myself !!!
one possible solution is that there are several grease gun "needles " out there that are small enough to get to the fitting they are fairly cheap... it's a needle that has a grease zerk on one end.....best $2.00 I ever spent

good luck

 

What and where do you grease on the U joints. Do you put the grease gun on that nipple like "zerk" and try and get it through the small hole in the middle? If so I can see where a needle would really help.

 

If you're talking about one of these:



you can't properly lube a u-joint with it.
If you're talking about one of these:



That's what I use with the flush fittings I use on u-joints:

 

I didnt know they made that!! Sweet I will get one today!
Thanks Boys

 

thanks !! for the pics AC, the second one is the answer, and yes you can grease a typical zerk with it tou just have to be centered on the "ball" of the fitting

 

Yeah, it'll work on a "standard" zerk, just a PITA. They are really meant for flush fittings as pictured.
