1) There is leakage out the one side. Photo attached. The axle bolts were fairly loose. Could that have caused a seal leak leak or should the seal be changed?
2) As I emerged from the the burnout box there was a deep short grind sound and a band loud enough to get the guy in the box to take off his ear muffs.
I did the launch and run as usual and at home that the leaf clamp had moved up enough to jamb itself up in the housing.
I think that the bang was when it released itself as the burnout ended. BOut is off the foot, maybe a line lock is in order. photo also attached.
