Gearbox Judder

[FEED Rocket]

Mine only ever happens when im going very slow or in a high gear at low revs.

mm I think you\'re describing "bucking" here.

Cheeky Chimp! Its the gearbox underneath, and it sounds like its about to fall off. It just clunks around.

I have something very similar, although mine feels like its the engine lurching back and forward. I\'ve just replaced the diff and diff mounts so everything is fine that end, PPF is also fine as I had it off changing the diff. One thing I did notice is that the gearstick seems to vibrate now when i\'m on throttle!

Juddering on part throttle or high gear at low revs is really annoying tho!

my car has been developing this for quite a while.

I am in the process of removing the engine, and I think the rear oils seal is leaking. So I think (hope) its oil on the clutch plate, or the engine mounting has failed due to being soaked in oil.

Lots of things can cause this, it depends what the judder is that your talking about.

if its when taking up drive (e.g slipping the clutch) it could be your flywheel needs a skim. I didnt bother skimming mine and this is why mine does it.

When does it happen with clutch engaged, part engaged, or open?

[OurKid]

Mine does it when coming off the throttle (clutch not engaged), or on part throttle going slow.

I get judder in reverse but think thats the twin plate clutch when its part engaged!

Mine is the same as yours ourkid but not in reverse although sometimes pulling off in first there sounds like a strain on the box and makes a nasty noise. Mainly on part throttle sometimes a terrible judder sounds like the box is gonna fall out, and then when downshifting a nasty sound as if something is loose from the gearbox area??

Ooooooooooooooh I get something similar...

When I change down the gears when slowing down it feels as if its juddering from the back. I thought it was the diff perhaps, but I\'ve fitted a diff brace and it doesn\'t seem to have made much difference.

However If I apply a bit of throttle the juddering goes a away

[gonzoninja]

Just like to say that I just picked my car up from having its tracking re-done and the guy said that the tracking was way out on the rear, so the juddering problem seems to be have been alleviated a bit (not completely sure as I\'ve only driven it a few miles)

Anyway, you may want to get that checked out first before spending lots of money on all the possible things mentioned in the thread.

Same here, so im guessing its a common fault, or something to do with having a twin plate clutch. Mine is going to WGT soonish so i\'ll ask pip to check it out.

[marky]

Get him to check it out and let me know please, really starting to do me fruit in. Had a wheel alignment not so long back so don\'t think its that.
