I'm in Coral Springs and have used
http://www.rayside.com for all wheel related maintenance. They've always been very professional until this last time. My trailer was returned without dust caps and I subsequently suffered a catastrophic bearing failure.
When I went back for the dust caps they put them on the trailer no questions asked... however, the person who took care of me tried to tell that they might have fallen off on my way home from the shop ... right.
Regarding the bearing failure, I was in to see them yesterday with a picture of their handy work. All they could do was stare at the picture, and say that I would be contacted by their manager. What is important is what they didn't say... They seem to take my initial visit seriously and at least for now are not trying avoid responsibility.
Up until now I really liked these guys. Hopefully they will step up.
My second choice is:
Truck and Trailer USA in West Palm Beach,

You might consider
K & K Mobile Home Supplies, 5882 Stirling Rd., Hollywood, FL 33021

They've replaced a pump for me. Small place "mom & pop" but they appear to know what their doing.
