i am having a problem with my torque arm mount. i have a 99 TA with manual transmission. I blew up my original motor and after i had it replaced my torque arm mount bolt keeps on backing out. I have tightened it about 4 times and the shop has tightened it also. mechanic has no idea why its doing this. i even loc-tited the bolt...it lasted a lil longer than usual and backed out. the bushing is still in good shape. anyone else had this problem or know of a way besides an aftermarket torque arm to fix this?...any help appreciated...thanks
