Alright guys, need some help here. Im getting a loud womp womp / chug chug sound as my tires rotate - the speedo jumps and matches the sound. Here's a video: Untitled When the video goes dark, I put the phone next to the transmission, which is where im hearing the noise emanate from. Its more pronounced as I slow down and tends to go away as soon as I hit around 60kph. What do you think? Bad wheel bearings? Tires going bad? Im on 35" MTRs so I don't expect the speedo to be perfect, but i've had this sound since I bought the truck and would really like to know how to get rid of it. The truck is a '91 HDJ81 w/ auto transmission.
