i have a 98 f150 4x4 5.4 L ext cab. i recently noticed that my right front suspension is squeaking when i drive and go over bumps or even the slightest rough roads. i am trying to figure out what it is. i know its not the shocks cause i replaced those. what else can it be and whats the best way to figure out exactly what it is?

 

Sounds like it's time for new ball joints. Best to do both the uppers and lowers at the same time.
