Spinning Prop...

Postby Big Al » Sat Jul 22, 2017 4:01 pm

OK I know it should but this bit shouldn't!

For a good while now I have had a constant squeal from under my car as I drive along. Not so noticeable at higher speeds but other noises just drown it out.

Haven't managed to get a volunteer to strap themselves under the car to see where it's coming from whilst on the move but today I think the culprit has been found.

MickEssex was kindly checking over the car, greasing nipples and replacing a wheel bearing when he noticed the front end of the prop shaft wasn't quite right. See photo:

The sleeve attached to the CV joint is loose. It doesn't move front and backwards but it does freely spin. I have checked the prop shaft from Alfie and that's fixed solid. There doesn't seem to be a method of attaching the two parts other than some small indentations near the edge of the sleeve. Could this be clamping marks/spot welds?

If anyone knows of a fix I'd be grateful to hear. I'm thinking some small tack welds evenly spaced around the join to keep the balance.

Hi - could you punch the sleeve onto the propshaft at 12,3,6,9 o'clock on the rear lip - could maybe be done from underneath without removing propshaft?

That' is what I would go for.

Just check Alfie to note where the indentations are relative to the CV as there are probably notches in the CV casting.

Align Matilda the same.

Or you pinch Alfie's prop for now and sort Matilda's later.

But GraemeT's option is doable in situ if the car is raised enough to wield a hammer.

Is it losing oil in the Gearbox?

Could be worth taking the prop off anyway just to see if the cap on the end of the gearbox with the seal on is all ok.

Thanks for those suggestions. Looking at Alfie's prop the indents are made differently but I guess serve the same purpose in just nipping the outer sleeve to the inner shaft base. I'm unlikely to get the chance of hitting it with any pinpoint force before Pateley so I will put up with the rattle (which I have done for over a year) for a little longer.

Maybe a little gaffer tape will stop it spinning for now... ;)

Isn't there a local garage that can just pop it on the ramp and sort it Al?

Driving all that way with a mechanical noise/defect wouldn't be the best plan with this being a 2 minute fix. it would annoy the hell out of me and its such an easy fix for your local guys.

Petrol-heads can't resist a look at the old girl. Useful being up the ramp, I now have a list of other jobs that will wait until after Pateley.

Mechanics of today were described to me as 'fitters' - they don't fix things, just fit a new part to replace the one that their diagnostics tell them is broken. Trouble is that sometimes they have to replace part A, then B, then C, then D (cos the 'puter says that's what you do with fault code P0140). Should have changed the fuel filter first.......
