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

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.

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

Also wear a mask,i've only just stopped coughing up blood and rust.

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.

Is this lobro or tripode you chasps are talking about?

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....

and the moral is always put reference marks on parts before dissasembly.



i know i did something similar but with a supra 3.0l dizzy

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?

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!
