We have owned our fleetwood Fairview (2000) for the last year. I'm about to drive it 800 miles and dh thought it would be a good idea to check and regrease the bearings. We've never done that before but watched several videos and read tutorials. Dh has the big piece back on after reassembling it but we haven't put the tire on yet. When we rotate it it (the piece. I'm not sure what it's called) there's a fair amount of friction and a grinding noise. We think maybe it is rubbing against the breaking mechanism? We're assuming grinding sounds are bad. Is there a trick to it? It was working well before and didn't have grinding noises then.
