[90cb7beast]

my trans is out and while its out i figured i would fill my rear mount cause it is f*cked up. well not even with 200 ft lbs of pressure from my air gun. the damn thing wont budge. can anyone give me some hints on how to get it out? please?? thanks in advance

deep creep and a breaker bar



and just incase you think 200ft lbs is alot its not get a real impact
