Please give me tips on how to refinance my car.?

Q) Few months ago I bought a used 2002 tahoe. THe monthly paments are pretty high. I want to refinance it to bring down the monthly payments. I need some tips. I've done research and found out that I should go w/ credit union. I also found Recommended Refinance Car Loan Companies Online such as Auto Purchase Loans, Car Loan Authority, or National Car Financing Instant Car Loan. With these loans I simply fill out an application and will be able to help get the lowest rate possible. But I'm not sure if i should fill out the application online. My loan is currently with Bank of America. PLEASE HELP w/ tips.
