Thanks for all of your opinions. I told em' I'd like a refund because I'm going to have to redo the work myself because I don't trust a shop who would charge 5-star prices and put out a job like this. The manager agreed but said he'd like to get proper-fitting dust caps, like those in place when they received the trailer, before giving it back. They'd banged up the new, poor-fitting ones pretty good anyway.
They couldn't find dust caps so they bought Bearing Buddy's and pounded those in but then discovered that one of the hubs is cracked. Hmm, did they crack the hub while trying to pound in a Buddy? So now they're looking for a hub. And even if they find a hub I'm not really happy about Bearing Buddy's on an axle that has a zerk fitting. I think they may have in fact removed the zerks from the axle.
Now even if I get a full refund I'm in considerably worse shape than when I took the boat in for service in the first place.
The old adage about doing it yourself if you want it done right is proven true once again. Last fall I took my SUV to the dealer for a summer/winter wheel swap, something I also normally do myself. They sent me out the door without tightening the lug nuts, which I discovered about 10 miles later as the wheels began to fall off. The quality of service in this town ain't what it used to be.
