Hello i have a craftsman mower that i had to replace a tire on and i can not get the wheel hub cap back on. I didn't damage it during removal or anything and i have been using a heat gun to heat it up a bit before trying to get it on but i have had absolutely no luck at all. I found a small cylindrical piece that fits snugly on the hub cap to help coax it on but no luck. Any tips or advice any one can give me will be greatly appreciated. Thank you in advance.
