306 dturbo noisy gearbox

Hi,

I have a 1994 L 306 dturbo, car has covered 135k and there is a noise coming from the gearbox which I could do with some help diagnosing!

Noise is a mid pitch rumble, not a higher pitch whine, more low pitch and happens whenever im driving, much more noticeable in 3rd 4th and 5th gears.

Its a bit worse when I close the throttle but completely goes away when i depress the clutch. The clutch pedal is very heavy and noisy in operation.

I have obtained a brand new Valeo clucth hopefully going in this weekend, im a bit worried though that this might be the box and obviously a lot more money....

any ideas?

thanks

Dave

If the clutch is heavy then perhaps you need a new clutch cable. Noise could be a driveshaft inner joint. Could also be a wheel bearing.

Hi,

Worst case : worn gearbox bearing(s). BE1 or BE3 tends to whistle at some revs, not to rumble... Which brings me to a bearing.

Cheers,

Clutch thrust bearing perhaps?

Start by checking the easy things first. Wheel bearings are the simplest to test, and a lot cheaper to repair than a gearbox. I would seriously consider a new clutch cable when fitting the new clutch if the action was getting heavy.

I would while the box is out either renew the release fork bushes or soak them in WD40 and work the rod back and forth till it is completely free. Then apply some copaslip. You can lift the rod up and apply the copaslip to the contact part.
