Propshaft removal

[tomti]

Hi all,

While I'm yet to work out if I need to take the propshaft out of our Minor (I think one or both of the UJs need replacing as it rattles like a so-and-so at what feels like 2000rpm or so upwards) I thought I'd avail myself of your expertise and advice about how to go about doing so if I do.

First things first, the manual doesn't mention anything about draining fluids before removal but I'm assuming the sliding joint at the front being lubricated by oilways from the gearbox means that would all pour out if I didn't and I don't know anything about diffs but I assume that won't just hang onto its smelly hypoid stuff if I pull the propshaft out willy-nilly?

I really hate the smell of hypoid oil so would definitely rather not make a mistake!

Thanks,

-Tom

Nothing will come out of the diff but you are right about the gearbox. Either catch the oil as you remove the prop or drain box first. Could be a good time to renew the oil anyway. Good luck.

Thanks! Much appreciated. Good to know what I'm setting myself up for before making a nasty mess of the front drive!

As you say, it's probably about time I freshened the gearbox oil - I can't remember when it last got done so that's probably a sign I should do something about it...

Before you start , mark the prop shaft flange.. differential joint so that you are able to re-assemble in the same orientation.
It can sometimes upset the balance if you don't. A " light " surface cut with a hacksaw , not near the bolts is all that is required.
Wire brush the internal circlips and soak with WD40 or penetrating oil if you have some.Make sure the holes in the yokes are cleaned with emery paper before inserting new parts.Support as much of the yoke as you can when knocking out the old.Open
vice jaws or blocks of wood for example.When the circlips are in hold the prop and bash the prop with a rubber mallet to ensure the joint is settled in it's correct postion. It's a good idea to cover the circlips with a smear of grease to keep rust at bay.

Another quick way to mark the prop shaft is to use a centre punch to mark two dots for reference.

make sure you put engine oil in the gearbox not hypoid ,
