Reply To: jerky drive

My problem in France last summer was a failed Bibax.  The bond had sheared allowing the inner to slip within the outer when the weight was on the ground.  However, there was enough friction remaining in the system to prevent the wheel being turned manually when it was jacked up so it took a while to realise the problem.
