Transmission Donut
The rubber donut jobbie that slides in and out of my 'box (type 9) is all perished and cracked. Can you still get them or will a new prop from
Mac#1 have a UJ in its place??

Dont know what MAC do, but I think that the usual is to have a UJ at both ends of the shaft. At least all the ones that I've seen have. ATB Ray.

The rubber donuts are unreliable and have been known to let go causing severe brown trouser syndrome. Don't renew it, get a new prop with
UJ's at both ends.

I haven't done this yet, but I understood that it was necessary to change the gearbox yoke when switching to a UJ. Is this not the case?
Thanks,
Shaun

Get rid of it. In the sierra, it was more of a shock absorber than a uj - I think the drive went via a fixed bearing, anyway its not like a uj,
especially not if you have a live axle setup. There were early horror stories in the robin hoods of donuts breaking and prop shafts bashing the
tunnek circular right next to the drivers thigh. Have a uj instead.

you can get one for ~45quid from ford.
I kept mine (rather than pay for a cush drive or TRT). If you have IRS or dedion there shouldn't be much stress on it

Searched back through some old RH forum posts and, yes, it is fair to say that with a fixed engine and diff there is not much movement but you have to
have a dead straight line from the engine to the diff - if there's any bend the donut as acting like a uj and flexing on every rotation.
