Mate, even if you triple check everything, if something is going to happen, its going to happen.
George lost a drive shaft as he was driving along
After lowering his car and giving it lots of negative camber, the inner safety clip of the drive shaft to the gearbox shaft broke, and as soon as he turned to a complete lock, the axle fell into the cv boot !
Luckily he wasnt speeding at the time so he got away with it.
Another friend with a Mitsubishi colt had a squeeky power steering belt, which he ignored for a couple of months, till one day it snapped and he stayed turning left in the highway
You cant predict everything. All I make sure of from time to time, is that my wheels are tight and with no play. Other than that, if you hear something knocking, have it checked
