so when i press on the accelorator pedal from any time when i have left my foot off of the pedal, my truck makes a rather fart-like noise from the front passenger side of the truck. this is only for low speeds, however. i had muddytazz take a listen and he noticed it sounded like it was coming from my d44, suggested perhaps i needed to tighten my wheel bearing bolts. just looking for other ideas as well. i attempted to do try his suggestion the other day, but didn't realize i would need snap-ring pliers and had to put it off for another day. if it makes a difference, this happens both in 2 and 4 wheel drive, hubs unlocked or locked in. any thoughts?
