Hi folks. You might have guessed by now that I am not very good with cars and just trying to have a go at fixing a friends picasso as they have zero cash. Last week I bought a front leg from a donor car and ended up with odd calipers. Rightly I was put straight and have rectified this by changing the discs and caliper carrier and caliper so all matching brakes. Thanks for putting me straight. So now I have connected a replacement used drive shaft that came with the front leg as the old one failed mot on a cv joint. I pushed the driveshaft into the gearbox end after pushing loads of grease in. It's not got splines it's like three round spinning heads that fit in. When I rotated the hub I could feel a tight spot as it rotated. If I straighten the shaft by Jacking up the hub it rotates fine. I popped the wheel on a just tested it but you can hear it catching. What have I done wrong this time? Thanks and be kind I am learning Cheers jed

The cv joint is designed to work at specific max angles. When the cars jacked up the hub is lower than at normal working specs. This can cause the cv the catch
Easiest way to check is with car on floor on full lock. You'll hear it clunking if the cv joint is fooked
Do you know the replacement shaft is s good one?

If it can be fixed with a hammer, then it must be an electrical fault

Pull the boot off the inner cv joint and check that one of the ball races on the tripode joint hasn't come off

Did it have grease in there before? Only a lot of those that go straight in the box bolt on and use the gearbox oil...

Thanks guys. Works great when horizontal. The minute I drop the wheel it catches. Other idle is ok. I can feel moving the gearbox slightly. Yes it was a greasy joint so added more. Thanks jed
