Have you Sir,or any other member had to replace the electric motor in the foot of a 36v unit ? mine just locked up,MG cust. svc. said the motor is $400 and you must buy a new shaft,as the old one needs to be broken to re&re the motor,,also just wondering,if that is necessary and the motor could be repaired by a competent electrical shop,and just purchase the new shaft,,tks.
