there is one fuse for all the dash gauges, so chances are you have a wiring problem to the gauge sender on the engine or the gauge is defective, which is rare.

SOURCE: 2 problems speedometer shows 30MPH when vehicle

thats a problem witjh gm ( speakers) try aftermarket kenwoods. as far as the spedometer goes check under the car at the tranny. there should be a grey plug with 2 wires. might be popped out so its giving incorrect speed.

Problem my be your throttle sensor.

SOURCE: there is a horrible rattling noise in the front

It sounds more like a possibly bad CV joint in an axle shaft or internal differential problem. There is no mechanical linkage to the front axle, its all electronically controlled. The front suspension is pretty good there aren't a lot of rattle type noises created from it. I need more info to diagnose better. Does it do it only moving? or stopped? over bumps only? in 4wd only? while turning? certain gears or speed only?
