Always check the vehicle over good and do really good car fax reports. This truck has been awesome it's a beast, drives great, pulls great and is very dependable. I bought the truck with 163,000 miles and now it has 229,000 miles on it motor good, trans good and the interior also good but My only concern is I think the rear ended maybe going out, but this far I am really happy with the truck.
I have logged over 202 thousand miles on this truck since it was bought used in January of 2007. Major repairs: none. Minor repairs: replaced EGR valve at ~175k miles, other than that, it has been just regukar, routine maintenance. My only complaint is the quality of the cloth seats in this vehicle, they easily trap dirt and dust, causing them to stain if so much as a bottle with condensation on the outside is placed in the seat.
The 2005 FX4 F-150 is the best truck out on the market. The power from the 5.4 triton is amazing and the overall style is great. I have not had any problems with it and i am very happy with my purchase.
I am the second owner of this truck. So far (158,0000 miles) great 4 wheel drive performance, good power, comfortable. Cloth seats wore out fast. a set of Wet Okole seat covers were in order. The front component of the 4 wheel drive went out because of a poorly designed vacuum part. I was able to fix it all myself in my garage for under $500.00. All in all, this has been a great truck. Update 11/23/17, still running strong, daily driver.
I have the short bed version of this package. First off the truck does its job as long as you don't abuse it. The clicking noise that is often heard is the cam phaser. It is a $2700.00 dollar repair and it will not stop the clicking noise (as admitted by Ford) the noise may stop for up to two weeks but will continue indefinitely after that. The only way to get it to stop is to purchase what is called the "Cam Phaser Lockout Kit" which is $700.00. I have put 80K miles on the truck and it has clicked since day one. have not had an issue with it truck runs good. Only other problems were the tensioner and the fuel pump module. which is a recall item no discount from ford $69.00 bad engineering.
