massive shudder

[Hughsie80]

If gearstrick is bouncing away, id say it was driveshafts over anything else.

Does it get worse under load?

Get underneath and grab a drive shaft, feel for any play, rotational, upa nd down back and forth ..etc pretty obvious when they're knackered.

Hi,
It only happens under load and then only between 40 and 60 mph, if coasting at them speeds the shudder stops, and there's no shuddering in any gear or speed under or over that range. Thanks
