Sierra CV Joints
Right, fun and games this weekend!
Decided it was a good idea to clean and regrease the CV joints on my Sierra 4x4 back end.
Several gallons  of paraffin later and a few minutes with 'The Tool' on the casing and they look lovely! Only problem is, I can't
get the FU$%^NG thing back together again!
I've tried a 'dry' run with no grease and as soon as I get the 4th ball in the thing jams solid. Is it just a case of needing to
apply the Moly grease before re-assembly and then it's fine or am I doing something fundamental?
Just as a note: I kept all the joints separate so it's the same parts going in as came out! 
Frustrated,
James

Sorry cant help with the joint problem, but what is "THE TOOL", sounds like I need one.
Gordon

iirc
the cage for the balls is put in in a certain relationship to the housing take it apart and index by one untill it works.

I had the same problem when I did mine but I did them one at a time so when I couldn't get the first one back together I took another one apart
noting which way the balls and casings lined up. They will go together without any grease. To get them back together you need to insert the balls into
the carrier, fit that to the outer piece then push the centre piece in at 90 degrees and then move the balls and carrier up and down to allow the
balls to slide into position while turning the centre piece through 90 degrees. In the same way as they only come apart when pushing from IIRC the
outside they will only go back together when working from one side.

Blimey! What is the world coming to when people don't know what 'The Tool' is???
The 2nd greatest (and most vital) invention for Locosters after the angle grinder: the knotted wire brush attachment for the angle grinder!
For is it not said:
"Man cannot live by cutting disc alone"
"...and lo, the metal was de-rusted and shiny and HE saw that it was good..."
or something....
See my photo archive for pictures of the joy it can bring! But be warned- he that does not wear thick gloves when using 'The Tool' is an
idiot! The grinder 'jumps' when you catch the 'upside' of it and I speak from experience when I say it does your skin/flesh
beneath no good at all!

Tim, Steve,
Thanks for the advice, I'll go and give it a go now. It was half 12 last night when I was doing it so maybe that didn't help! 
Cheers,
James

James,
Yes I had the same problem but got there in the end in a similar way to that described above. One of those things which is easier done than said (once
you've done it once at least...)
Cheers,
Craig.

Powered by Maclaren...
Finally got 'em back together about 10pm last night so thanks for the help everyone.
It's easy when you know how! My main mistake was I had the inner piece lined up wrongly with the outer- ie. it was 30° out
You can't say I don't seek help at the highest places- having failed when I got home from work I took it round to a friends house to get
him to show me how to re-assemble it. Which he did in about 5minutes!
And so he should... afterall he is a senior manager at Maclaren!!!!!
Cheers everyone,
James
... it's not what you know, it's....

James,
So does that mean that McLaren use Sierra Lobro driveshafts on their F1 road car then... Gold plated of course...
Glad you got it sorted mate, easy when you know how eh?
Cheers,
Craig.

You laugh but believe it or not they are in fact exactly the same CVs as were used in the Formula 1 car!!!!
He said the only difference was that the Formula 1 CVs were a lot looser as a guy would spend time smoothing the ball tracks!
I didn't ask if they were the same in the road car, but based on the above info it's not that unlikely is it!
They're all bought from the German company Lobro.
Cheers,
James

Can your friend in a high place possibly source us some cheap 18,000rpm V10s?

Don't know about that but I'll see if he'll have a word with his mate Gordon and get me one of them there BMW v12s from the F1.
It's only a mere 668BHP but I guess a bit of head flowing and few Metro turbos and it'll give out something decent.
It's only a couple of M3 engines welded end to end after all!

The F1 engine should be cheaper to insure than the RV8 based on engine size 
I don't suppose you fancy putting a step by step guide to reassembling lobro joints online do you? It's near the top of things to do
next..

Cant say he's the one who let's McLaren down every season then! He just does the Hubs obviously! Perhaps he ought to teach the others his
technique? Then we might begin winning again... still at least old DC's going!
