Shudder when pulling away
 

I'm just going to put this problem out there because a couple of my mechanics have tried to chase it and not found it, and maybe one of you guys has experienced it.

There is a shudder-type vibration which I can feel when pulling away, most noticeable from stopped when pulling away in 1st, but also from 1st to 2nd. You can feel it more when the car is more laden. So for example I will be stoppped at traffic-light, into 1st, up with the clutch, then the shuddering happens for about 1 second at the beginning of pulling away.

One mechanic said propshaft or other UJs and changed them, but no difference. Another thought oil getting to the clutch, but no, it's fine.

A real head scratcher for me.

Thanks.

Hi ya.

Try prop shaft rubber mount and also gearbox mount they get soft with age or oil on them So have a slight whip effect going on .
Also I know this sounds daft but try inspecting the rear axle had it before the woodruff key can wear badly with age and past miss use so can kick inside the drum also seen at times missing ones can slip badly !

Keep us posted

Kind regards

Check engine mounts , followed by gearbox mount . If its a two piece prop shaft , make sure the centre support is not worn away allowing the shaft to move around in the carrier . Then check UJ's carefully for side to side movement .

Tom;

As others have mentioned, a worn Driveshaft Center Support, which allows excessive movement will cause this. Earlier (two donut) version, especially when outfitted with the whimpier replacement donuts are more susceptible to this. To check, grab Driveshaft and give it a healthy tug in various directions...it is undesirable for it to audibly hit anything solid with a clunk, the forces applied when drivetrain is loaded are even more substantial.

Good Hunting

I'm with Ron. Check the most obvious (and cheapest) source first. Next after that is the universal joints, which are similarly likely culprits. My best guess? It's time to replace the u-joints and carrier bearing support all at once, for another 100,000 trouble-free miles. Total investment? Less than 50 pounds.
