Bought the truck in June of 2008 with 40K. Things I have absolutely had to replace:Rear axle bearing seal ($40), thermostate for radiator with seal (20), both front wheel bearings (250 a piece). Things that were wants not needs:Throttle body (700), cruise control cutoff switch (50), 4 motorcraft shocks and 8 ball joints total, front upper and lower and rear lower, front sway arm bushings (bushings wore out around 50K, buy moog bushings, Ford material is for the bushings is poor) ($600-700 for suspension parts) AC vent door components (300). AC was blowing cold air but the doors were stripped and the air was being blocked because they were not opening properly. This happened around 50K.
Its a descent ride...lots of hesitation with the throttle response tho.
Ford has issues with the throttle bodys and have since made them an "upgraded part." Cleaning them will not solve the hesitation issue. Its $700.00 from Ford but fixes the hesitation. This was more of a want and not a need but wow it helped a lot. I have had the new throttle body about 12K and its doing fine. It was something about the old ones didnt have proper spacing in certain areas and were making wear spots inside? Also the material for uses for its front sway arm bushings is subpar I believe. Bushing made a squeaky noise when going over speed bumps. Moog is what I replaced them with along with the ball joints.
The AC fresh air blend doors and acutators that open the doors. These are 2 of the main problems with these models. The gears that open the blend air doors on the acutators are plastic and strip out and the doors themselves are also plastic and break. Im not sure if its cheap plastic or a design flaw. Unfortunately its a real pain to get back in there to repair these areas. The parts were $300 total from Ford. I just had it fixed recently. Some owners have had there vechicle for 200K and never had this issue and some owners like me it broke at 50K. Also the replacement throttle bodys are upgraded parts. Cleaning them will not solve the issue. Its $700.00 from Ford but fixes the hesitation.
