Stupid question alert!!

I’ve ordered some new UJs, bolts and yoke boot for my front propshaft. I ordered the more expensive ones with the nipples. (hope they are the correct ones I just guessed that the props are the std ones and haven’t been swapped out for another type. Anyway – do I need to fill these with grease – if so how, what tool do I need?

Pack the bearings well with grease on assembly and you should be OK, but regrease now and again with a grease gun. Keep pumping and you'll see fresh grease oozing out of the seals.

Would they come with grease as std, and you refill them at each service or something? How come you don’t get little boots to cover the nipples like you would for a brake caliper? Seems strange to me...



EDIT: **** sorry mate i didn't see your post till i had posted my own, i'll see how much a grease gun is on ebay - can't see them being much.

The grease nipples have a spring loaded ball bearing inside which seals them - like a one way valve. Just clean thoroughly before applying the gun. New bearings usually come grease packed, but not with a lot of grease - a little more won't hurt.

Thanks for your help, knew it would be something simple!

I'll find out what grease is required and buy a gun - best to get them well packed.

Castrol LM or similar.

The new UJs arrived today so I went to the workshop after work with my spare prop. Managed to get the old UJs out without much of a fight and was happy to see that the replacements I'd bought are the correct size.

I'd also bought a new gator to replace the old one (seemed stupid not to) when i spit the prop sections down I noticed the seal that sits in the screw cap was shot to buggery. I've had a look on eBay, paddocks and land ever spares don't seem to sell them - any ideas where I can grab one of these?

Hmm, it's not shown as a separate part in the parts book. I'd just pack the splines and boot with grease and be done with it. I think the seal is there because the gaiter is optional.

small note-
when you grease gun the uj's dont over fill. watch for the seal expanding and a small squidge o grease comin out.
pumpin too much in blows the seals off!

beleive the seal in the sliding joints was a fibre one, to allow breathing as prop extend / retracts. make sure the yokes are in line on re assembly to avoid vibration.

Ok I'll just re-pack it as is then with the new boot. I could always make one out of cork - if I had any cork that is.

Would be nice to find one though made out of rubber or polyurethane or similar.

Thanks for all your help chaps, i'll be getting the dirty bits of metal I the parts washer tomorrow or Friday and give them a clean before I reasemble it all.
