Swivels - CVs - 101s

[101RRS]

Working on my brakes I have spotted that the the filler plug on the 101 swivel hubs has had grease nipples put in them - so clearly the previous owner has been using grease.

No discussion on benefits of oil over grease and vice versa please - it has been done to death.

Now on my old subaru CVs I just used to use high pressure CV grease - a yukkie molybneum (I know spelling) dark grey grease - worked fine.

So my questions are - given each hub is speced for 800ml of oil, if I use grease instead will the stuff I used in my subaru be OK and how much should go in.

What is the best product to flush the stuff that is in there out so I can put in either oil or grease (haven't made my own mind up yet).

Cheers

Ok - to get the discussion going - lets have another discussion on the pros or cons of oil vs grease:)

Oil gives better lubrication until the seals start to fail, or more importantly the balls become scored (which on a 101 can be a problem).

I know that the Penrite Oil, US site previously recommended semi-fluid grease (http://www.penrite.com.au/files/2ZIIFZOTFD/SEMI-PIS.pdf)for Land Rover swivels but can not find the old link.

It comes in a cartridge for use in a grease gun, so having the grease nipples would be required.

OK I will bite.
My 101 is running EP90 in the CVs and only has a slight leak after a hard high speed run.( I do have some pitting due to stone damage)
The british RAEME report in the 1970s started to touch on the use of grease in the CVs of a 101......given garrycol the web site.
Mobil make a special grease for steering boxes and is a semi fluid over a wide temp range.( I cant remember the name)
If the the grease is clean and everything is working OK.....why fix it.
I am leaving the oil in my 101 CVs for the same reason.
Just remember the grease nipples will allow easy over filling with a power grease gun.
I would just fill the CVs up using the end of the grease gun in the filler hole without the plug and grease nipple.

Working on the brakes - I just noticed the grease nipples.

As far as lubrication goes I have only changed the engine oil and filter at this stage.

After the brakes are fixed, the next job is replace all the other oils and grease etc - so I want to change whatever is in there - don't actually know at this stage though passenger side swivel has some serious weepage so if it has grease in it - it is a bit of a worry. I suspect it was leaking oil so the change to grease and some oil is still in there with the grease - the job for next week.

[I] have never had my CVs apart, but there could be a oil seal leaking between the the diff and the CV causing the CV to leak.
I found on the front drive shalf to the diff the transfercase seal leaks as the normal vibs due to the high unijoint angles.
The drive flanges wear a bit on the splines and the fix was to use a speedy sleeve just to tighten up the seal a bit better. where it runs on the drive flange[/
Check the oil cooler hoses from the engine to the cooler as they have been known to fail due to old age.
Pirtek or similar can make them for you.I]
