Knocking driveshaft - Which one?!

[garth]

I have a diesel 106.

When I turn left a drive shaft makes a noise like a helicopter, it's worse at speed.

Amirite in thinking this is a driveshaft, and if so, is it the O/S or N/S?

It could be a wheel bearing or a CVJ (Constant Velocity Joint).


My Tip: Why not stick to Left Side and Right Side?

O/S and N/S are a bit redundant. (as far as I am concerned).
It confuses the fcuk out of people and for no practical reason.
And if you are talking to foreign people it makes it worsererer.

Mostly you can pinpoint which side if bad enough but if only subtly it can be more difficult and need more detailed inspection.

You could act stupid and see wot Kwikfit say.
Costs nothing but may be of some help.

I've had it on the ramp and neither have play. Hence why it's confusing me.

It doesn't sound like a wheel bearing.

CV Boots visually look fine - I'd just do the whole driveshaft - It's £39 quid delivered and minimal hassle, but I'd rather not do both!

Due to the differential action the outside wheel has to turn faster than the inside wheel (Or visa versa) when cornering/driving around in a circle.
I would guess the joint with the higher speed when cornering will be the one making the noise.

So if it is noisy when turning left the rightside joint/shaft will be fastest.


Maybe a load of shite mind you.

I found this pish:

When i had a knocking I replaced the O/S wheel bearing, it didn't go away. but the noise was clearest/loudest when this part was under stress.

I then replaced the N/S one and still no good.

I replaced the O/S drive shaft and still no good.

Then I replaced the N/S shaft and it went away, like magic it went.

Because the vibration travelled and sounded off the opposing disc or whatever it duped me, but well in the end it got a full set of brand new parts.

Just be careful.

It's a driveshaft if it's a 106. my AX (same chassis/running gear as a 106) o/s went so I changed it. Within a month the n/s went too. If I were you I'd do both at once, as they are cheap and easy enough to do.

^^^ This

At 40 quid a throw, I'd just do both; the law of sod says whichever one you choose, it will be the other one and, at that price, it's just not worth the aggro.

I had an AX and went through 3 in a year. IIRC you cant seperate the CV joint from the driveshaft so it all has to be replaced.

I'd LOVE to see St3v3 do this in 5 minutes. I think it took me around an hour all in to do one shaft on my Clio, from start to finish on my drive.

It is easy tho.

I would have thought that if you do both you'd have to drain the oil from the box - certainly on the Clio the n/s requires you to remove the boot from the gearbox, which then results in all the oil pissing out. Only the o/s is sealed. Of course the 106 may be totally different with sealed shafts both sides.

Gearbox oil is bloody expensive - prob another £30-40. I'd be inclined to drain and collect, if it looks terrible, change, but otherwise I'd be inclined to reuse.

I'm presuming you have all the tools etc to do it, but if not I'd be able to pop round with a few bits to assist - I'm only in Eastleigh.

[garth]

Thanks for the offer -

I've got everything I need I believe, I'll just do both at the same time. It's not that bad yet, just irritating.

Cambelt was done Monday, I'll do an oil and filter on Saturday, then driveshafts next payday.

It hasn't done mega miles at all (44k) but I'll probably change the gearbox oil anyway.

75/80 gear oil is £9/L in Halfrauds, so another £18.

Might as well.

It's surprising how little wear you need on a bearing to make a lot of noise.

I had a wheel bearing on an old Escort making a horrific racket, I really thought the thing must have started to break up. So took it off, hardly any sign of wear, no noticeable play.

Fitting a new bearing cured the noise.
