We just had ours repacked in Louisiana at a truck repair place. We figured they would be more into "chassis type" stuff. Most MH Dealers are just that - they are good for dealing with MH issues - not so much with axles, bearings, grease, brakes, etc.
Anyway, it was first time on it with 90,000+. I watched the entire process and the old grease/bearings seemed fine, but repacked them anyway.
Recommend new seals as well.
Our total cost was a little over $300 for the fronts - that included new seals.
Discussed the conversion with the truck stop owner - he said best to stick with whatever came with it. Odds are, there is a good reason. Leaking oil would make your front brakes useless - and start a fire while trying to stop!!
We like grease!!
