so finally got my crower stage 3 h23 running...now have a different problem, when im driving and shift(doesnt happen everytime) or when in at like 3-4k and just let off the gas it makes a pretty hard clank or thud type noise....i think its 1 or 2things
a. rear motor mount
b. loose or near broken axle

what do u guys think?
