What to do if you overtightened a suspension bolt
Accidentally over-torquing a suspension bolt creates a major dilemma because replacing a damaged bolt can require buying an entirely new rear crossmember if it is welded in place. Misreading torque spec sheets can result in extreme over-tightening, leaving owners unsure whether the stressed hardware must be replaced or can remain.

“If i torqued my timing belt tensioner pulley to 68lbs vs the spec of 20lbs. Could that potentially cause the tensioner to fail and make my timing belt loose?”source ↗
