UJ's

[ric p]

It is that UJ time of year - for all of you who have too much Wedge knowledge floating around their heads, a quick question. For a 400se, what is the socket size for the rear wheel hub nut and to what torque is it tightened? 41mm and a lot is my understanding and pin the nut with a split pin once tightened.
Thanks

It is 150lbft

Thought it was 230ft lb - hence 3/4 inch drive is advisory - must dig out my bible! Cant remember the socket size but I've never been metric and seem to recall 1 1/2 inch (38mm). If you dont want to damage the threads I've used Loctite thread-lock in the past and not lost one yet!

yup i agree 230 lb/ft and 3/4 drive socket

Having seen the set up with the wheel off, is there any reason to undo this nut-can the uj's be replaced by disconnecting at the 4 studs at the brake disc end and drifting the ones on the hub out in situ. Or am I missing something obvious?

The first couple of UJ's I replaced I did with the drive shaft still attached, but it's not easy to get the joints assembled whilst working under the car. The needle rollers can fall out if you are not very careful. On balance I would say remove the drive shaft from the car and replace the joints on a work bench.

I have done it on the car, thinking back though I am not sure what damage if any was done to the bearing. Straight forward I thought.

Its a 36mm socket on the hub nut and yes its MUCH easier to do on the workbench, having replaced one of the buggers yesterday, does anyone know where you can get greasable versions?

Richard Thorpe sells a greaseable version !

Done one side today without removing the hub (38mm socket). Also replacing the discs so undid the 4 studs holding the disc on. This allowed the shaft to come free and is a lot easier doing 3 of the 4 uj's on the floor. Still bugged one of them up bending a couple of the roller bearings so on the phone to Peninsular in the morning for another. However the 2 bolts holding the rear caliper on the drivers side were emotional. That bit of chassis won't rust as it is now flesh covered.
