Without wishing to state the obvious I take it you have undone the two bearing retaining 'hooked' bolts?

again the obvious is the outer end out of the hub, i usualy use an old large srewdriver with out its handle to drift these out against the colar at the diff side of the mountting, dont usualy have a prob

Hello John, sometimes you need to heat soak the alloy casting to get the interference fit sealant used on the bearing outer race to release the bearing. I do have a small lipped brass drift that can just about get on to the outer bearing race and usually find once the tension is broken, the bearing comes out easily.

Failing that, a shock loading (Big hammer!) on the drive shaft usually dislodges them. Never seems to wreck the bearing.

Have you got a dead blow hammer?

Last time I had this obstacle John, it took a big cold chisel (shaped and blunted to fit snugly against the bearing collar on the driveshaft) and a 4lb club hammer...

tried it Jim

access is tricky as this V6 has a handful of exhausts underneath

4 16mm bolts and the housing now appears loose ,,,

well well...

see my 406 blog, (thursday) for more..

the intermediate bearing was ok, no problems.. the issue is the driveshaft is stuck fast into gearbox

the only time i have seen the shaft reluctant to part company with the gear box, is when i forgot to knock it clear before undoing the clutch houseing bolts, this causes the shaft to become stuck as the box moves slightly out of square to the engine

hi Malcolm, hmm.. even with the box out on the floor and all pressure off the shaft, it's not budging. guess I will have to leave it as it is, and put the gearbox and driveshaft onto the new engine.

If the tri axle ends seem all to be ok and not falling apart, can I just mesh the two ends together, add grease and not worry about it ?

well 90 kilo's of autobox was thrown into my dear xantia and duly taken to a gearbox specialist and driveshaft is now free to go it's own way

a big hammer seemed to be enough

i tried many things including hanging the box off a crane (by driveshaft) and adding to it's weight with my hammer to no avail

6 hours to remove a few splines... gutted

many times I have done this, a few mins max,

...but this one does not have the rubber outer seal which I condemed in the past as being pointless.......... the one tthat stops rust?

i know this one has been a little s**t, but when removeing gear box with 0/S shaft still atatched to int mountting and rear of engine, you will bend the inner half of the drive shaft

its been a nightmare Malcolm

to be honest, changing the driveshaft in the near future will be a walk in the park now it has finally come out.. I am more concerned for the diff and the gearbox...

Will know soon enough what was damaged
