Ball joints

[Okiefromwatonga]

Ok every one, here I go:

I just bought a 03 F250 SC SRW 4x4 with a 7.3 in it and 116k on the clock. I love the truck but just recently (in the last two days or so) its developed a bad "thump" in the front end that can be felt in the floor board of the truck every time it hits a bump in the pavement. It also "knocks" or "thumps" when you turn the wheel to either lock but isnt felt through the steering wheel. I was at first thinking that it was the ball joints as the tires are cupping a little on both outer edges, but after crawling around under the truck for a bit last night, they look like they are fairly new being the boots are in good condition and they all have zerks in them. I am at a loss as to what it is. Please help an unexperienced PSDer in diagnosing this problem.

maybe the bushings on the sway bar?

THere are two vertical body stablizers. One on the passenger side and one on the drivers just behind the tires. You can't miss then, they are about 9 inche's long. They control body roll in turns, etc.. Sounds like the bushings are going in at least the one side. If this is your problem they are about $90.00 for the two of them.. Byt the way mine had about the same mileage on it when mine went up..
