Was hoping maybe someone could kinda help me out. Im not the best at cars.. but heres whats up. When i turn the wheels or go over bumps and such, the truck tends to squeek at the front and a little at the back. Also, after running it for a while, idol or driven, the truck likes to skip, and shake a little. Its random at skipping, not a constant.

Its a 1999 Ford F-150. The engine is pretty much a stock V8 5.4l except for the K&N Air Intake system. Your help is appreciated =].
