Hey I recently purchased a 99 nitro 882. An upgrade from my basstracker. I am still getting used to all the new features and am very unsure about my trailer that now has a brake system. I want to change out the rims and tires because of rust and very cracked tires. When i do should I also change brakes or hubs? What is a good idea to keep it rolling smooth. Also what kind of oil do I put in my trailer in the front where it has the oil spout? I tried to read my manuel but it doesnt really say. Can anyone help out this NEW BOAT OWNER???
