Hello,

I'm just renewing the front UJ on my front propshaft, quite an easy job so far but I've just fitted the new part and fitted the circlips, but nothing is snug! The cups aren't tight against the clips and there's tons of play! Can it only go in one way around (ie, flange or prop?), or have I been sold the wrong part? I want to get this sorted, pronto!

Thanks for any help!

Ohh bum flaps. Yep, it's: RTC3921 Cheers buster, I'll take it down to swap tomorrow. I'll be driving an NA with rear wheel drive only!!!! Good God
 
Heey wait a minute. My 90 doesn't move without the front propshaft on :eek: but it does with the difflock on. Technically that means it's a front wheel drive unless I have the difflock on, (which is never), so I am infact driving a front wheel drive, which is mainly driven by just one of the front wheels! So this thing is a fecking one wheel drive!!! What the hell :eek: Will driving it with the difflock on knacker anything when only driving on the rear axles?

Alright cool, so even when I'm turning corners with the difflock on (again only with rear prop connected) it should be fine! Yaay :) How is driving with the difflock on and the front prop connected any different though? Surely when I turn corners one of my rear wheels turns quicker than the other anyway, effectively the same thing???
 
Cos the centre diff which is the one you're locking only divides the power transmitted to the two props allowing them to travel at different speeds. The diffs on the axles allow the wheels on that axle to travel at different speeds i.e when turning. if you remove the rear prop make sure the handbrake drum is secure ask HB ha hwhehhe hhahehheaheh aeheha heh ehh eaheh eh heaheh aheah eheha hehah.
 
lol :) so just to be absolutely certain. Driving with the difflock on and the rear props till in place will not damage anything?
 
good good! I still don't understand why it knackeres something up when you have the front prop connected though! Whyyyyyyyyyy and what breaks / snaps or whatever?
 
let me explain... :D

As you corner, all 4 wheels move at different speeds, cos they all take different paths.

If you had NO diffs, when cornering you would either simply not corner, or, if the tyres had good enough traction, would be forced to go round at different speeds, so stressing all your transmission.

A normal (not LSD) diff will, in its very nature, put power through the easiest route. So, if you have one wheel in the air, or one prop missing :)D) then the diff/s will put all the power that way. Take off the front prop, all the powe goes to the front flange, as its easier to spin that than move a LR.

Engage difflock, the centre diff is then forced ro give out the power evenly. Front flange rotates at the same rate as the rear one, so you regain drive.

Select difflock with all 4 wheels connected on a dry clean surface, drive in a straight line, no problem.

Turn a corner, the wheels go at different speeds, so all the transmission parts get stretched/stressed/twisted to allow this, and then that energy gets stored in the transmission as wind-up, or, the tyres let go and slip to allow it to relax, or something breaks.


Simple as! Any help? :)
