1994 F150 XLT 5.0L M5OD Standard Cab Long Bed 193K miles
I inherited this truck from my stepfather when he passed 6 years ago and neglected it for the first 5. It has now become my main project. In the past few months I have replaced the rear driveshaft u-joints, all of the ball joints, radius arm brackets and bushings, all sway bar bracket/end link bushings, distributor and tfi module, spark plugs and wires, air filter and fuel filter, and airbag clockspring assembly. I have changed all of the major fluids (transmission, transfer case, power steering, antifreeze, brake). I have visually inspected both the front discs and bads and rear drums and shoes and determined that nothing needed to be replaced, though the rear drums have a bit of a lip on them. I have been thru the front hubs and re-packed the outer wheel bearings (done when I did the ball joints). I have done the "bounce test" and determined that the shocks are pretty much ok. Last weekend I spent 16 hours detailing her inside and out. She runs great on a daily basis. No random shut downs or weird vibrations at highway speeds any more. But there are still a few lingering problems I would like to try and solve.
1) Power steering loss - This only happens when I am trying to crank it hard in either direction with the transmission in neutral...like trying to turn hard into a parking space with my foot down on the clutch. If I give it some gas to rev up the rpms the power steering comes back. Bad pump? Bad steering box? Power steering fluid is fresh.
2) ABS light comes on - An intermittent problem that only happens maybe 1 out of every 20 times I start the truck. It goes away if I shut it down and restart. Occasionally when the ABS light comes on the emergency brake light will stay on too. Again problem goes away if I shut down and restart. Bad RABS sensor? Air in the system?
3) Check Engine Light - only comes on after the car has warmed up and usually only after I have reached highway speeds or gone into overdrive. I have an Innova 3145 code reader. When I run the KOEO test it comes back as 111 with system passes, but then the memory code always pulls up 172. 172 is an "O2 sensor lean" code. Googling this code leads to lots of people with lots of different solutions, from replacing vacuum lines to EGR replacement, to O2 sensor replacement. Any and all help welcomed.
4) Brakes - When I am braking, I feel the sensation that one would normally feel when you have warped rotors but without the shaking of the steering wheel that normally accompanies it. I usually don't feel it at higher speeds....it is most prominent from 35mph down to about 10mph. It actually feels more like the truck is hopping. It is very minor, and most people would probably just ignore it and chalk it up to it being a 21 year old truck. I am wondering if this is related to my occasional ABS light problem.
Here she is....posted it in the " what did you do to your truck" thread earlier.
Thank you for reading my stream of consciousness and for whatever help you may offer. Please help me make her perfect!!!
