That's not too bad, sounds like an honest dealer.. if you had done it youself, it would have cost about $70 total, front bearings are $40 or so, and brakes are $20 or so.
2200 pounds?? Wow, how did you get your Tracker so light?? Mine is over $3000 with my gear in it., even more with me and my boy.
I think they are what 2700 stock?
I'd be lucky to get 22 out of mine, but I have heavy tires.
