juddering
 

can anyone help. i have a 1992 t1 310d motorhome.it starts ok,ticks over ok,but once your driving it judders.on acceleration it happens.it helps the fault if i keep the revs up i.e. drive in 3rd when it should be in 4th. the van has a turbo fitted and its had a new clutch.

Replace engine and transmission mounts -- a bad transmission mount will cause a thumping or drumming vibration on acceleration due to excessive up and down movement of the transmission.

I would also check the rubber mount for the driveshaft center bearing if you have one, as well as for play in the universal joints in the driveshaft.

Drive shaft out of balance and bad U-joints come to mind.
