UJ Replacement
Discussion
Replaced the outer rear drive shaft uj on 400SE today. Thanks for info from forum.
UJ was Hardy Spicer HS179 obtained from local motor factors.
UJ was replaced in situ on car by
1. Jacking rear of car and placing on axle stands
2. Remove rear wheel
3. removal UJ cir clips
4. push our old UJ
5. Re assembly - reverse of above.
None of the suspension or drive shaft needed to be dismantled.
Hope this helps anyone else needing to do this.
If the inner UJ needs replacing at the same time as outer after step 4. the 4 bolts holding the drive shaft to the UJ could have been removed to allow the drive shaft to be taken out for inner UJ replacement.
J400BBW is now back on the roads in Essex with new MOT.

How do you manage to push them out so easy.
Maybe I was just lucky!Turned drive shaft so outer yoke was vertical. Cut and removed UJ rubber seals. Used socked and mallet to drive bearing cap through yoke (will not go all the way as UJ fowls on yoke). Turn drive shaft 180 degrees, drive UJ using steel rod and mallet to push cap outwards through yoke. Pull out needle rollers. The UJ can then be positioned so that it pushes on the edge of the bearing cap to drive it out completely.
The drive shaft can then be pushed sideways out of the outer yoke. Place drive shaft on 3x3 timber located on top of A frame. Using hammer, hit UJ to drive out remaining 2 cups.
Hope that all makes sense.
I have never come accros drive shaft UJ's that could not be driven out using a socket and mallet. Prop shaft UJ's have been known to use a little more persausion though.
