Knocking On Gear Change

[Bigjeeze]

Has anyone any ideas what might be the cause. I had thought it was the bolts or the roll restrictor but no - they are fine. I then thought maybe it's the gearbox flange to half shaft problem with the splines wearing but again I don't think it is.

 

I am leaning towards it possibly being the bushes in the wishbone as I can't see what else it might be.

 

I have done 163k - and as far as I can tell everything else is in good order.

 

Basically when changing gear (once moving) I can if I get the revs right change very smoothly and this is what I mostly do - but if anyone else drives the car or I forget sometimes I get the clunk that feels if the roll restirctor is shot.

Has anyone any experience of this on the MK2 Diesel - It looks and feels fine - you can't rock it or move - it has no apparent wear or damage - as I said the bolts are tight and not moving.

 

There is a small amount of play in the D/shafts but there are no other signs of wear, no clicking no knocking etc so I don't feel this iit.

 

Any advice would be much appreciated.

Thanks Paul

 

I had thought to change them but at

First port of call would be to give them a good visual inspection, there is often some evidence of failure. Edited June 25, 2010 by sparky Paul

Haven't done any work on wishbone's ? have you? if there tightend at wrong posistion you might get a clunk from shock tops .Or check for loose wheel i once drove 200 miles with one thinking I was limping home with shafts on way out.

There are only two - One at the Gearbox end and the other at the CAmbelt end - Both seem fine. The roll restrictor is the third bearer and as I say it looks and seems fine.

No I haven't touched the wishbones since January when I did the clutch. Even then all I did was remove the bottom swivel joint. I suppose it is conceivable that there is movement in the top bushes but t doesn't feel like it's in that area. It's seems to be on the drive train somewhere.
