Propshaft

Really dumb question, but am I right in saying that when my series II is in two wheel drive, the front prop shaft will not move whilst driving?

it will turn unless you have free wheeling hubs disconnecting hubs from drive shafts

I do indeed have freewheeling hubs, basically I ve got two new UJS ready to fit and I know all four need replacing, now I know that the front prop shaft isn't spinning whilst driving I ll do the rear ones first

Ok so I ve changed the UJ but one of the planes of movement is quite stiff compared to the other? The other plane moves easily by its own weight! The stiffer one is still easy to move by hand, thoughts?

you might of dislocated one of the roller pins , have you filled it with grease so its spewing out ?

Either you've dislodged/lost a roller - which is a bugger.

Or, more likely, you've got one or more bearing caps pushed on too far. This is easier to fix. When I did mine I pushed all caps in as far as they would go, fitted the circlips then rested the whole lot on the floor with the cap downwards and ****ted the shaft with a mallet to push the cap back out flush onto the circlip, repeat for the other three...when finish it should be very nice and free and flop about like a rag-doll's head...

Thing that surprised me is that I'd driven a good few hundred miles and passed an MOT with the old UJ's completely shot with no bearings left - apart from a slightly "funny" noise when in 4wd or with hubs locked no ill effects!

The action is still really smooth, would it not be jerky if a roller has been moved? I think it might be to do with pushing the cups on too far? Would putting the prop back on and doing a few miles maybe loosen them off?

No it would probably just get hot and probably fill the bearings with swarf. Did you try what I said and just persuade them...

I ve just given it a go and it has loosened them significantly although they're still not super floppy like the old ones were, I m sooooo hoping I don't have to take them off again
