I know this seems to be a common problem with fords, at least i seem to see fords around all the time with a noisy squeaky suspension. and it has finally happened to my truck. seems to be only coming from the rear drivers side right now.

by the way, its a 2007 f150 extended bed, super cab.

i did a little googling around and got mixed results. anyone know what this could be and what i can expect to pay as a ballpark if i took it to the mechanic?

Just grease everything you can find, dont take it to a mechanic as you will replace the whole suspension by the time you've solved it.

will that fix it?

Could be lots of things....

Ball joints come to mind

Sway bar bushings/links fall apart eventually, I'd start there.

yeah thats one of the things i heard it could be from my bit of googling. what could i expect to pay to have all of that replaced (parts+labor)?

what trim package and motor does it have? also 2 wheel drive or 4 wheel drive?

Sway bar links are like 30$ ea, bushings are maybe 10$ or less not sure, you could do it yourself fairly easy.

it's a 6cyl 4.2l, 2 wheel drive

Is it a "clunk" sound over some bumps? I'll guess it's the bushings and only like a $150 job at many mechanic shops.
