more than likely the shocks are not what you hear squeaking it is rare if ever that a shock squeaks.
there are several bushings and joints that tend to dry out and develope squeaks in the front end and the thing to do is spray them up with some type of silicone lubricant one at a time and bounce the vehicle to find which is squeaking.
also the newer explorers use the torsion bar type front end and have a type of A-arm on the top which has a bushing on each end that gets alot of dirt on while driving.
these get very dry and rusty, i have replaced a few of them on the work trucks.
the parts to replace a front suspension are not cheap at all so find your problem before you start looking for new parts.
the explorers that i did the front ends over on cost about $400 and i did all the labor that was just for the lower balljoints and the upper arms and bushings.
the joints on the upper arm are not replacable and must have the whole arm replaced.
