Hi everyone, new to the forum, brought here by my '08 F150 XL. Amazingly, I bought it with 20k miles on it in 2014, and since then it's been running really smoothly. The previous owner didn't do much to it, cracked a side mirror, but other than that the truck just sat. I had to replace the power steering pump pulley (the plastic had become embrittled from just sitting so long, and complete sheared apart when I was making a turn), flushed brake fluid, radiator fluid, and transmission (5 speed manual), fuel filter, engine air filter, and tires. Besides that, just the normal stuff, oil changes etc. I do a variety of things with it - 8hr+ highway driving once a month for work, 10min commute to the office, hauling various home improvement and landscaping stuff, so I feel like any of the major issues would have presented themselves, but so far I just have two things that I'm going to try to check into.

First was my ABS and brake lights staying on, I've read around that it's likely a fault signal from the ABS system. When I crank the engine, they lights are off but after about 1-2 seconds they ping on. I'm pretty sure that it's the ABS module that blew out, I've checked the two front and one diff sensor, didn't see anything unusual. Strange thing is that this issue came up pretty much right when the power steering pulley blew. I didn't find anything wrong with fuses etc either. Second is that when I'm driving with my window down, I can hear a squeaking noise that doesn't seem to be speed related, but I only hear it when the car is moving which is really odd. It might just be my belt needing to be tightened up, but I've also seen some posts about U joints etc.

Any recommendations for parts that might need replacement now that I am hitting the 10 year mark? It's sort of hard to follow the typical service manual, not much wear and tear, but I'm more concerned about rubber/plastic parts that might be starting to degrade, or metal parts rusting or needing new grease.

 

You need to get the ABS codes read out with a computer. Squeaking is most likely the u-joints.

 

Probably should have included that. The codes I had pulled are:
C1300 - ABS Pump Motor Circuit Failure
C1266 - Valve Relay/Valve Relay Supply Voltage Failure
B1342 - No description available
