[Healeys] drivetrain vibrations

[Martin Jansen]

The most common cause of drive train vibration is the compression buckle- just
forward of the front bulkhead in the main chassis rail. This compression
buckle changes the elevation of the transmission in relation to the rear end
causing the drive shaft to operate outside of its design perimeters this will
cause a vibration through the centre of the car,same effect as a worn u joint.
This will eventually effect the pinion bearing and rear transmission bearing.
Certain suspension modifications can also cause this problem.
The chassis' purpose is to maintain consistent information to all functioning
components of the car.
