Vibration shudder I have a ldv maxus van and while i am driving between 30 - 60 mph the van shudders and vibrates. I find it is at its worse between 40 - 50 mph however, if im driving over 60mph i find that the problem doesn't occur. Any help would be extremely appreciated, thanks Dave

SOURCE: I have engine vibration in

Good call on the engine mounts, this problem has had a lot of TB owners scratching their head. Hope you used genuine GM mounts, aftermarket mounts tend to crush too much sending you back with the same problem you started with. With aftermarket mounts, the engine will not be as high as needed, the rubber isn't as stiff. Seen this many times. The other thing to check is you tranny mounts. Engine and tranny mounts are usually the culprit with vibration while in gear and stopped with TB's. What type of plugs did you install? Have you cleaned your throttle body?

get it put on a code reader and see if there are any codes first,this may lead you in the right direction rather than do a guesstimate

SOURCE: Freelander Deisel,constant vibration,shudder.

remove drive shaft and all vcu components, take for a short drive ( car will still drive in 2 wheel mode, if vibration gone suspect could be vcu , if still felt at front suspect ird if still felt in rear check diff mounts then diff out put bearings and nose end play.

could be a worn universal joint on the driveshaft

i had the same problem with my pickup. thought it was unbalanced tires. turns out one of my spark plugs wasnt firing and throwing the motor out of balance. problem wasnt notices till i hit 65 - 70 mph
