I have a squeaking that I can pin point to the left front area of the truck. After much trouble shooting thought the cause was the hub/bearing assy. Changed it and squeaking/squeeling still persist but over a much larger rpm range and louder. Noticed a pully wobbly and not sure which pully it is yet. Will update when I do figure it out. Any ideas or suggestions to what it might be would help greatly as I want to continue to save money for upgrades but want to get rid of the noise before pursueing the goals for my truck.
