I have tried all morning to reassemble this, 2 neighbours have nearly had it buried in the side of thier merc's as I'm completely frustrated!!!

Please can anyone tell me if there is a technique in reassembling thisas I'm at my wits end


Thanks

Hi Rapid

Been a long while since I changed a CV boot on a Lobro type Sierra shaft so I had a quick gander at the Haynes workshop manual

I have a sneaky feeling that you have dissmantled the CV joint ?

The manual states that the Lobro CV joint is not user servicable & should be replaced.
I guess they must be factory assembled then sealed to prevent the bearings from pulling out of place.

On the face of things the CV boot is only thing that should be serviced by the user.

I expect you know, the CV joint is held onto the driveshaft spline with a circlip.

If you have managed to dissmantle the CV joint itself this could be an indication of wear in the bearings & probably best replaced with new joints.

That said, there may be a way to re-assemble the joint ( Manuals are not allways right )

Hope you get it sorted

Edited to Add

New ones are available here

CV Joint & Boot Kit

A reasonable price if you are doing a single joint but going to cost a bit to do all 4

Turn the center of the joint with the cage to 90 degrees and it will pull out complete, reassembly is the reverse. If you cake all the balls in grease that should hold them in place in the cage while you do it.

yep it is the CV joint and I disassembled it by rotating it through 90deg to remove the cage but can't get the begger back in without it locking up.... think it maybe worth just replacing if they are only 19.99 each not worth the hassle or risk if they could be shot anyway?!?

Thanks gents

I have used that supplier for CV joints before & have never had any customer complaints re the quality of them

You not the only one, mine fell to bits when i went to fit it. When it was stored in a box. Gave up in the end, could get the balls back in but would lock up. Left it with my dad, he had it back together in 10 mins.

Here you go a demo on you tube.

Thanks Robo, just spent another 15mins on it and result got it back together, once i worked out the direction of the grooves on the inner splined cage and then worked out the dirwection and twist with the flange it seemed to make sense but it was so sensitive, ended up putting to ball bearings in first then twisting and put in 1 ball at a time, not yet seen the youtube video so will be interesting to see how their method compared to mine but it's a bitch of a job to do.... never mind sorted now!

Thanks guys for your comments and keeping me sane
