There is however slight or great, a definite potential for compromise. Head bolts are the classic example of single use fasteners due to the potential for stretch.

With all of the moving parts, thrust and torque associated with suspension, why take the chance? Just my $0.02.
Exactly! I think the point some folks aren't getting is that these particular bolts and TTY method are specifically engineered to stretch to the point of plasticity (as explained in the OP reference thread). It WILL NOT return to its original length. More importantly, the next time you apply the same torque-to-yield method it will either break apart or be severely weakened - ready to break.
