Propshaft Query

Post by IanC » Sun Aug 11, 2019 3:37 pm

Hi,
I'm going to change a propshaft U/J on my (auto) SE5a. Not done one before, so this'll be fun/educational/annoying. However I've a couple of general queries before I start:
1. Does the forward end of the shaft simply slide out of the gearbox?
2. If yes, does the oil then come pouring out (even if I've got the rear of the car jacked up)?
3. If yes to 2, what's the way round this?
I don't want to lose a whole load of fresh oil as it's recently been changed .
TIA, Ian

When I removed the prop shaft on my SE6 I just drained the gearbox. Easy really.

It just slides out of the tail end. Refitting it needs to be exactly positioned right. Try twisting to get the gear to mesh and it will slide home easily.

If the car is relatively level, the oil may just dribble slightly, nothing to be concerned about. The only way to avoid it is to use an old propshaft front end. If you have the back end of the car jacked up it may not even dribble.

If you try to remove the engine and box it will pour out of the back until nearly empty. I know that isn't what you are doing though.

hi, thanks for that, but i don't really fancy draining the new ATF and either binning it ( it was quite pricey) or putting it back in (risk of introducing dirt as well as being a bit of a fiddle).

If you put ATF in it, it needs dropping double quick! Hopefully you used AQF?

Ian, if you can tie/tape a plastic bag tightly over the back end of the gearbox once the shaft is removed, it will prevent too much leakage and you can then top up to suit afterwards. Unfortunately AQF flows easier than manual gearbox oil!😁

Hi, I meant ATF as an abbreviation for automatic transmission fluid. I'm sure the specialist guy who sorted out my torque converter and autobox seals will have used the right fluid for an A4LD. I don't have a old propshaft front end (good idea btw) but hopefully I won't have too much of a leak if I try as you suggest and see if I can raise the rear of the car enough to minimise loss of fluid.

but i don't really fancy draining the new ATF
I agree with AJL on that you should definitely drain the ATF out and use the oil recommended in the manual which is either EP80 or EP90 cant remember which it was and I don't have the manual any more as it went to Tom (demonbluedays) when I passed on ownership to him.
Regards Terry H
Edit. Forget everything I posted, I thought you were talking about a manual box for some unknown reason.

it’s an A4LD automatic box Terry.

With the back of the car jacked up, you shouldn’t lose any oil Ian.

If it is an A4LD then ignore my comments as it should be ATF Dexron III of course!

And so it proved! Unfortunately that was the only bit of good news, I broke a large bench vice tring to remove one of the bearing cups (buy Chinese, buy twice) so had to resort to professional assistance. Sadly the droning noise on over-run (vaguely from the transmission tunnel area)which prompted the change of U/J is still there. I had initially thought wheel bearings, but they were OK, and was persuaded it was the prop, truth to tell the front u/j had a very slight play, the rear one was fine. So I'm no further forward.
Any thoughts what a droning/whiny noise when lifting the foot off the accelerator could be?
And just to intercept the jokesters, the noise is there whether or not there's a passenger!
TIA,
Ian
