Had a go at replacing a rear bearing recently and whilst at it found the brake dust shield hanging on by a thread around the 3 bolts.
Broke off completely with very little force whereas the bolts did not. Decided not to replace at the time, didn't want to bugger up the 3 bolt heads, i was losing light and euro car parts is about half an hour away.
Surprisingly, only a few days later the other side came loose, it sounded like the exhaust had fallen off! Jacked it up, tin snipped the thin connecting part and yanked it off.
Googling a few posts on here, some say they're not completely necessary and to replace them i'd have to take off the bearings.
Anyone else running without them? whats the worst i could expect not replacing them?
