When I put the car into gear it shifts in the gear just fine (any gear) let out the clutch it rolls but if I get on the throttle at all I hear a grinding noise and it does not want to roll. I have a brand new clutch I just installed and new axles. Basically my friend had me put this stuff in his car that didn't fix his problem so he traded the car to me now I'm on the mission to get her back on the road. Could it be the LSD??? Any help would greatly be appreciated as I am completely new to mazdas thank you
