Hello. There are multiple things that may cause loud noises when stepping on the gas pedal such as axles, valve lifters, and catalytic convertors. I suggest you have a technician inspect the vehicle since there are several things that may cause this noise. However on 1998-2002 Ford SUV’s and trucks, the catalytic convertors are commonly known to become noisy under the exact circumstances you are describing. I strongly suggest having a qualified mechanic inspect your truck’s noises, they will be able to accurately diagnose the issue.
