first check and see if the section nearest the opener is turning
normally -the opener has double female interconnect between the male
hex drive on 1st screw section and motor drive- if undamaged then
problem is likely screw section binding clips. inspect the junction
points where the screw sections combine. there should be a barrel that
slides up from the long throated side to marry the 2 pieces and a half
barrel that then snaps under it so it can not slip down.if you lost a
clip and the barrel is free to travel the noise will be generated by
slop and only thing holding screw pcs together is the confines of the
housing.
