Which Transmission Bit?

[Albert]

Hi all, its my first post so please be gentle..........

 

Have got major no-go problem with my 02 plated Alhambra 1.9 tdi 115PS manual 6 speeder 47k mls.

 

With wheels turned for a right turn and on pulling away from junction the car lost all drive and all that could be heard was an expensively loud 'gear crunching/not meshing properly' sound whenever the clutch was released.

 

Having been towed home by mate, I did a bit of searching through previous posts and did a bit of on-car invest and would like your considered opinions. Here's the bits that I know:

 

Putting the car in any gear and releasing the clutch, the grating/non-meshing properly sound is heard. This 'speed' of the noise increases with gear selection. (1st slowish grating sound - 5th faster grating sound).

 

The car moves very slightly as clutch is moved to roughly the bite position but not enough to make the wheels turn even when clutch totally released....(grating noise doesnt change in pitch or tone at any clutch position the sound only changes with only with accel position or gear selection)

 

Additional info: The gear selector on top of the gearbox can be seen to move when gear lever moved. No apparent smells as per slipping clutch or oil loss as per totalled gearbox.

 

I'm thinking of a problem on the output side of gearbox, especially with the 'speed' of the noise changing with gear selection. This thinking is also coupled with a couple of posts with very similar symptoms which are linked to driveshafts.

 

With little in the way of facilities to fix the thing, I am curious as to what others think and also to prepare myself for the bill.

 

Look forward to your replies ty

Hi Albert

 

Sounds like a CV joint has gone, You proberly did not do it any good towing it, unless you lifted it or put it on a trailer.

 

first thing to do, lift the front end off the ground, and turn eash wheel in turn,and see if there is any noise ? and if no noise, try turning one wheel and looking at the other (on the other side) and it should turn the opposite direction.

 

If no noise and the opposite wheel turns its not the CV or the Diff, but poss the drive into the gearbox or the box itself (very hard to diagnose when not at the car)

 

Hope that is of some help

From my recent experience, from the way it happened during a right turn, I would say nearside CV Joint has broken up.

Cheers Radio 2 & Iain

 

Lifted front end, selected first, on steadily turning either wheel no noise and other wheel turns in opposite direction

 

BUT

 

if the wheel being turned is given an extra bit of 'umph' it sort of slips and a rachety noise can be heard. (same as main symptom noise but obviously slower) This happens when turning either wheel.

 

So possibly CV joint then?

 

Iain could i ask how much you paid please

Iain could i ask how much you paid please

 

Couldn't tell you...

 

Mine turned into a litany of problems when it went into Fraud Stealer. Eventually returned to me 3 weeks later with new CV Joint, new Flywheel, new exhaust F + R (it needed this for MOT), new flywheel sensor, recharged aircon (as they took the engine out), replaced power steeering fluid and various minor other bits.

 

I was charged

Many thanks Iain..........I can see you've recently had a bit of work done.

 

I'm finding that mine likes to go the garage every 3-4 months..........keeps the garage owner smilin!!!!

 

Will post results later in week when I get Albert taken in.......

Just a quick post as I'm having problems getting garage time, have noticed that with car in gear, clutch released and grating noise giving it some, the speedo starts to indicate plus speedo increases with accel.

 

Does this mean there is an output from the gearbox and so it and clutch is ok?

 

Where is the speedo 'sensor' located then?

 

I know post is half dead but like to have an idea before eventually putting Albert into garage.

[Guest alan]

had a similar problem with my 130 tdi se at 122k turned out to be drive shaft that is in the middle cost about

[sepulchrave]

Why hasn't anyone mentioned the differential? ;)

[Albert]

Only thing with that is its within the gearbox............but could still be as surely the diff is being driven, hence the speedo movement, but not meshing correctly with driveshafts and giving that expensive grating noise. Hope its not the diff!!!

get someone to engage a gear and release clutch slowly when noise starts look at the driveshafts in 1 is spinning then its defo a c.v. joint, but towing and trying all this, it may now be a driveshaft that is required.

[Albert]

Well in my nievity and haste in getting Albert into a garage plus a recommendation from another mechanic I took it into Mr Clutch.......oh dear I hear you say!!

 

After them initially taking the gearbox out, sending it away and then finding out it was the short driveshaft between box/diff and RH driveshaft I eventually got the car back.

 

While the box was out I got the clutch and slave cylinder replaced. The clutch I got replaced as 'why not' as the box is out and the slave cylinder was weeping. Also I was lucky enough to have a worn dual mass flywheel, which was replaced at near

the rattling could be as you say hydro lifters, or ive known injectors to give a similar sound, you would have to crack each one individually to know, your whistling noise, is this under load or at tickover , will it go if you depress the clutch when stationary ?

 

edit , thats if the tappet noise is from that area ? or is it exhaust or heat shield ?

[sepulchrave]

I might be barking up the wrong tree, but, did Mr Bodge forget to tighten a clip on one of the turbo pipes, that would produce a nice whistling noise. Check your pipework on the high pressure side of the turbo.

[Albert]

Not had chance to look under bonnet yet, but had rattling noise this morning but went within a coulpe of minutes. This leads me to think that as the car was siiting in 'nice' Mr Clutch garage for well over a week I may have a bit of gumming in one of the hydraulic tappet ports.

 

If I depress the clutch it make no difference in noise.........

 

Dont think its turbo pipes as it runs brilliantly and the 'spinning whistling' noise has gone.

 

BUT all I really need is sort of convincign that its not the clutch etc

[anadin]

if the whistling noise has gone i'd say you have nothing to worry about, re hydro tappets ask your garage to give it some flushing oil at the next service
