I just dropped my 17 foot featherlite 3110 car trailer at the local featherlite dealer last week for a replacement jack, repack/grease wheel bearings and attach a registration plate. Total cost is 315 dollars which is lower than we expected. I've owned it since 2006 and this is the first service I've done on it. A friends trailers wheel bearings catching fire prompted me to get it done.
The bearing cost 180 bucks to regrease and this also included checking the brakes.
The replacement jack was 30 bucks.
A replacement tail light cover was 15 bucks.
A wheel to go under the jack was 17 bucks.
