Can't Find Zerks on My Driveline U Joints?

[Racorman]

I have a 2011 30’ Winnebago Itasca Class A and do my own oil changes and lubes. I have no problem finding the (9) zerks on the front steering components but am at a loss to find any on the (2) driveshaft U joints. I pulled the boot covering the splined section of the shaft, but it looked like it did not require any lubrication. Over the years I’ve been doing my maintenance I’ve always look to lube the driveshaft as I’ve done with my vehicles from the 70’s to the 90’s …… but don’t see them on this motorhome. On the road I’ve taken it to Ford Dealerships to do oil and lube and I’ve never seen any residual grease on the U joints that also is a hint they may not exist. Any thoughts? Thanks!

9 front zerk fittings, I wish I was so lucky I counted 22 on mine awhile back, There is one on the sliding drive shaft, P series chassis.

Thank you all for replying 🙂

Lubed for life. When they need lube, their life is over.

My old 1999 F53 had zerks. My 2006 F53 does not have them.

Sealed joints last longer.

Typical OE universal joints are not greasable. If you want to grease them replace them with greasable ones.

Many are lubed for life and have no zerks.
