Thanks for your responses. I'm UK so I'll give Stevson Motors a try, thanks antijam. I have drained the faulty one, removed the endcaps and now the pistons move freely, but re-assemble and fill up and no resistance. So it looks like a job for the experts and another hole in the pension! Ian, MaxMG, ...

Can someone suggest a repairer (or repair) for Lumax shockers? One has ceased working on rear of car (oil level fine).
Thanks,
Ian (MaxMG)

Glad to hear yours was easier Kameron. It goes against the grain to bash ancient machinery with a hammer!

Marv, It was the inner splines that had the damage/wear which when the shaft hit the slinger on the way out caused the jam. Damaged the slinger but didn't matter as fitted seal kit. I don't think the shaft (left hand viewing car from front) would have lasted much longer so am really pleased the job ...

Marv & Co,
The shaft flew out like a rat out of a drainpipe, through the garage wall and killed the neighbour's cat. Seriously though, it was well stuck and jammed again in the oil slinger, so it's a well past it shaft!

Hi Marv. Been busy getting the boat (yes, another expensive toy!) ready today as the weather too good for garage work. However, gales and rain tomorrow for the English Channel so I'll get on with it. Whole job started 'cause oil leak of course....did the other side no probs with parts from Mad Metri...

Thanks Marv. that's tomorrow morning then! Good job you just managed to keep it clean!

When removing rear hub it came off easily (worn out!) but left the shaft in place and it is stuck in the diff. Is it ok to drift it out from the other side? Thanks.
