How much is it to replace all four shocks (struts) on my Ford Expedition? on 2000 Ford Expedition

How much is a tune-up? Also, occasionally the truck makes a loud humming sound and someone once said that it could be the water or fuel pump going out, also the engine light does go on and off. Other than that, our Expedition has never given us any problems.

Spark plug replacement and shocks are listed in the Estimator tool.

The check engine light really needs to be tested to find out what is going on that needs attention.

Humming sound - the fuel pump makes some nominal humming from the fuel tank area, but it's not necessarily an indication of pending failure.
