I have a 97 2wd f150 OK so I was going through the school parking lot and it was very muddy and I was not paying attention at the moment and u went in to it and almost got stuck and threw mud everywhere and when I pulled on to the road mud flew all up under the truck and when I start crusing around 45-65 mph there's this weird banging sound under the driver side of the truck by the front and back tirer it almost sounds like if u hit a stick in the road and it pops up and hits the frame of the truck but its not and IDK what it is or where to Start looking please help

 

Without more info ( engine size, trans., etc.,) i would say it sounds like you got water up on the engine ( plugs, wires, coil packs, sensors, etc.)and grounded out 1 or more cylinders causing a misfire or backfire condition. But at this time its strictly a guess.

 

It's a 4.6L v8 IDK the trans tho I think I got the coil packs wet because it has a slight skip to it

 

Wash the mud off, probably crammed behind the wheels.

 

Yeah, always start with washing the mud out of places that spin. Mud will cause what ever it is (wheel, drive shaft, axle, etc.) to not be balanced and will make your truck feel like it's falling apart. You'd be amazed what a tiny chunk of mud can do lol.

 

Same with snow/ice. I had snow packed inside a wheel one time where I couldn't see it, and it drove me batty!

And the danger with that is melting and refreezing. You drive around with some snow in there and heat it up with the brakes. When you park, it melts and refreezes in a smaller volume inside the wheel throwing it even farther out of balance.

Winter fun! Mud can be just as bad when the temps drop off.
