I had new u-joints installed last summer on my Class C Ford E350 and I went to grease them and can't get to 3 out of the four (only one I coulod reach was the front). c I bought a new 'right angle' connector and still can't connect to the zerk fitting...Is this an installation problem? Can't figure out why they would make serviceable u-joints with zerks that you can't reach and "service"...Any thoughts?

It could be simply a rotation problem. Block wheels a few inches, roll rig slightly to get fittings to an accessible locatiom

Company that made U joints probably isn't the same as who made the driveline yokes. As mentioned, you may need to rotate the driveline so there is some angle to the U joints, which will provide clearance to get the grease gun in.

Spicer replacement U joints...Have tried rotating driveshaft, etc.Was hoping for some recommendation for a new, really thin walled zerk connector fitting :)Thanks!

These mini grease guns have a much smaller connector to the Zerk fittingsMini grease gun

Try an adapter like this:Grease gun tip

I had a difficulty like that on the front wheel bearings. I fixed it by replacing the zerks with angled ones. Inexpensive and easy to do.

It's been a long time, but I think that you can get a connector/grease gun fitting that is smaller, I don't think it locks on, you have to hold it on the zerk square and firm.

I have tried the right angle - can't get it in between the yoke (the diameter of the connector itself is too large)...don't see how the needle will work either because I don't have a straight shot to the zerk. It's nuts! Either the shop who installed them paid no attention to the orientation during installation (and I'm not even sure there is an "orientation"), or ...I don't know.

Lincoln Lubrication 5803 Grease Needle Nozzle

The picture does not show it, but it should have a soft rubber tip.
