I had my 2000 5.4 lifted up 6". A-arms, spindals, Bilstein shocks, Eibach coils, the whole shot. I had this done 6 months ago and it has always made noises but now it really squeaks over bumps or when i stop or accelerate. Is this normal or does the place i went too suck? Im hoping it just needs to be relubed or something. If anybody knows anything about gear ratios, what size gears do i need now? My stock tires were 235 R16 and know i have 285/75-16. My current gears are 3:55.
