200 Tdi front UJ

The ball seals on my 200 Tdi front UJ/steering joints are leaking. They currently have oil in them, but I'm told you can put in a one shot greese instead.
Is this so and is the greese enough to get into the bearings? Whats it called and where to get it?

You can put grease in them but do not think that it will solve your leaking problem. The grease gets thin when warm and still escapes. Swivel ball seals need renewing and if the balls are badly pitted they will need to be replaced as well.

It's called one shot but heed what he said.^^^^^^^

Also as a pedantic point the drive shaft joint in the swivel is also not a UJ, it is a CV joint in the modern axles.

My 200 has one shot grease in, been okay for 8 odd years so far.

Thanks guys, Helpfull indeed.

Tottot; Thanks for the causionary warning. I know and understand this. I have also been told that I can replace the seals without having to fully strip the hubs. By cuttung the seal and placing the cut at the top???

Yes that seal dodge does work, I found it bit of an arse getting the cut seal around the swivel ball, but not much harder is wheel off, disconnect the brake hose unbolt the swivel from the axle and remove the whole assy in one go then upend it with halfshaft in the air and replace the seal.

When up-ending with shaft in the air, put it in the upturned wheel to act as a stand. Studs back through bolt holes from rear etc. Makes it easier to work on. Saw it on Bitanica Restorations on the tube
