driveshaft grease
Dillinger1977 - 21/5/05 at 08:02 PM

what type of grease is it in a sierra driveshaft joint? the outer (wheeside) joints are a bit stiff after its been standing for a few weeks and it could probably do with some more packed in before it gets connected up the upright bits. is it 'special' grey grease or just filthy normal stuff?

(im trying to avoid stripping them.. )

lithium based molydisulphide (Duckhams LMB10) according to the manual, dirty grey to start with.

When greasing UJ's be careful you don't pack too much grease in, overwise you are likely to deform the dirt seals allowing dirt into the UJ bearings.

How mcuh grease should you put in each one? When I took mine apart to clean and paint oily stuff ran out!

Just wondering whether that was knackered grease or theres an amount to use....

Oily or watery stuff would be knackered grease.

Probably a good idea to give the joint a good bath in the solvent tank and blow it dry with compressed air before re-packing. When it's clean and dry give it a thorough inspection with a strong light to look for pitting or excess wear.

I've always packed joints full of grease, wiggled them about and wiped away the excess with a rag -- others who know better may chime in with the proper answer.

about right there, just squidge plenty of moly grease (as detailed above by Peteff) into the joint, wobble it about, squidge some more in and put the boot over it!

Cool, thanks!

A bath in the solvent tank eh - erm thatll be the bath full of thinners then!

Bah!, who needs eyebrows anyway

My parts washer is currently filled with that environmentally friendly citrus stuff -- it was free since the tins were rusty. I think it's still flammable though.

If oil ran out it has seperated from the grease = knackered. Otherwise someone has been dicking about before you got them = knackered.
Ive used squirty carb cleaner and electrical cleaner before (safety first - eye protection). Just make sure it is all cleaned out otherwise the cleaning stuff will knacker the new grease (our bearing plant clean bearings in kerosene but have to make sure it is fully out before greasefill - they use centrifugal spinner and another oil based product that is compatible with the grease).

driveshaft CVJ's imo should be full. Excess will be squeezed into the boot. Sealed bearings need careful quantity so that seals arent under hydraulic pressure during use. Our plant works on 25 - 30% void fill for sealed bearings.

With new CVJ's you get a sachet in the kit - try and picture the size and this will be a good guide (although they will give you the minimum to keep profit up).
