B21 front wheel squeak

[BruceWard]

My B21 is making a similar squeak in reverse and also has damage to the boot. My guess is that we both need to clean that universall joint, install new boots and lube.

Does the U joint have zerks on it so it can be greased? I'm trying to figure out if there is some preventative maintenance that can be done here. tnx.

No, those u-joints are not greaseable.

When mine was noisy it was the wire clamp had caught some brush and was bent out of shape so I replaced with a SST hose clamp. Also there is a plastic sleeve coming out of the bottom u joint boot that is fairly snug around the drive shaft and if something got wrapped aound the shaft that could generate a squeak.

Its pretty easy to undo the clamp and slide the boot up the shaft to inspect the front U joint however the back end u joint is not easy to access at all.

On mine it is the front U joint. There is no way to apply grease with the boot in place. My guess is Kubota expects the grease inside the boot to last as long as the boot does.

I sure appreciate all the input!

What I thought was a rubber boot over the U Joint was more like a hard plastic that had a hole in it. I straightened the plastic where the whole was and readjusted the clamps and wouldn't you know it, the squeak stopped. I also sprayed some lubricant(Fluid Film) through the hole into the boot over the U joint and covered the hole with duct tape. I'm glad the squeak was a minor fix. I love my B21 and was not looking forward to more intensive reapirs.

Glad it was a simple fix. The parts list in the manual also replaces the wire type clamp with a regular SST band clamp. I did that and it hasnt come loose after three years.
