hi new to this not sure if this is the right place but got a 81 Subaru GL for free. runs good and off roads great better then most trucks but lately when driving it there is popping from the right front side and sometimes shakes really bad up and down hill unless i push the clutch in. Once i push it in it all goes away. tires do need to be balanced cause lost the weights. so idk what is going on and i checked CV joints and everything and there all good so any ideas. its my daily driver and cant afford to have it down
