uh oh... think there is defo sumit up with my driveshaft

[Šįk]

wen i accel hard in 1st mainly and in 2nd occasionally there is like a weird cracking type of noise coming from the front left wheel, wen i get to 3-4k and above... any1 know what this is etc...? how much is replacing the driveshaft?

 

[Mostro]

Driveshaft replacement cost me £210 all in; £100 driveshaft, 1.8hrs labour + VAT

Didn't have those symptoms though, I had a loud clicking/grating on hard cornering.

 

[Šįk]

ok not as expensive as i thought :S but ok... if it was to f**k up then would it cause any problems? i.e like when a cambelt snaps it causes all sorts of other f**k ups...

 

[Mostro]

I think you just lose drive tbh, but I'm no mechanic......

 

[bing_17]

Sure its not the cv joint mate? Do you get the noise any other time, under cornering etc?

 

[mini-valver]

CV joint isn't inter-changable on the 172 shafts IIRC. New D/S is the best fix.

If it was to go, you'd have a flailing D/S twatting into stuff in the engine bay, if it snagged on the floor and ripped it out of the box, you could end up needing a new diff.

depends how it breaks as to how much damage it could cause - main concern might be loss of the steering if the CV joint breaks up and seizes

 

[james21]

loss of steering??????! what are you talking about!

 

[Henry]

it's a constant velocity joint..

loss of steering??????! what are you talking about!

he's right. if it seizes (extreme I'll admit) the steering could jam

 

[Henry]

typical outer CV joint below. you've got a spider locked onto the splined end of the driveshaft which holds a number of ball bearings which are located by a cage which is, in turn, housed by the outer casing of the joint. the purpose of a CV joint is to allow for steering/suspension movement whilst it's being driven by the engine/box

it's rare (although i've been unlucky enough) but, if the cage breaks up, you end up with a load of uncontained metal and the joint can jam, meaning you've no control over the steering

that is abit extreme yes!

hence why split cv boot is an mot fail
