My truck is a 2004 Ford f150 fx4, the suspension on the front is bad. I bought it with 65,000 miles and it was bad. I have had to replace it after nearly hitting a semi head-on after hitting a bump and it about bounced me off of the road. This has been an ongoing problem that I couldn't figure out at first. I have called Ford corporate office with no return phone call. After looking on the internet at the forums about this truck and year, I determined that this is common. I don't know if Ford knows but they should. It has cost me over $850 to get the sway bar bushings replaced, tie rod ends, upper and lower control arm and shocks. I drive alot a miles in a year.
