need to replace the steering gear box if you don't it could lock up on youth most you should ever turn those is about 1/4 turn at a time

There are fuses under the hood, Follow the + wire from the battery and you will find the fuse box.

IF they replace the pinion seal, they had to retorque the crush washer and perform a pinon pattern. If that wasn't done right, then it could make noise.

I would strongly suggest a full diagnostic test using a good quality computer with uptodate software, perhaps a local specialist? This will really help to narrow down your search, obviously deoending on how good the person doing the diagnostics are. Roger

go to www.totalcardiagnostics.com and you can read codes

Noisy crownwheel and pinion whine , most likely worn carrier and pinion bearings,new bearings may not cure the fault, as the back lash and tooth engagement has changed and may still whine.

Your alarm sytem went off because it thinks you disonected the batteries to steel the truck, ect, call a ford house,i hate these new computerized cars, were stuck with them, check you owners manueal, Matt

There is nothing to reset on the computer. This kind of problem is hard to find. Most likely it is a connector issue, but could be a bad bcm. I would get under the dash and jiggle the relevant wires to see if anything changes while jiggling. If it does, keep jiggling individual wires and locations to isolate the problem to a specific wire or connector. If you think it's a connector, check to make sure the terminals are fully seated in the connector such that the pins are going into the terminals. If none of that works, play around in the fuse box. Take fuses in and out. Swap relays around, etc.

Call Warn they may have those springs.

it can be a fuel problem could be the regulator or the fuel filter, if its not getting enough fuel it will turn down the air flow, can also be a vacume leak if its broken or leaking, this would mean its getting more air than it needs.

Have you installed LED bulbs? That would cause the issue.

check the light control modulator.

Looming fault or bad connection. Check for codes.

Power draw causes heat generation. As the alternator is loaded down by current drawn from it, the windings heat up. This is normal, and this is why alternators have fan impellers on them. If you have lots of equipment running, the power draw may exceed the alternator capacity. Modern alternators have overcurrent protection built into them, but this doesn't mean you can't burn them up. Excessive sustained power draw will overheat the alternator and it will eventually fail. The best thing to do is either lessen the load or upgrade the lternator.

Your oil is under pressure as it is circulated through the engine, and at low RPM there is less pressure pumping the oil around. With the broken dipstick, I presume there is an oil-pressure leak and at normal operating speed there is enough capacity to maintain proper pressure, but the leak is more than the engine can overcome at low speed. I would suggest replacing the broken dipstick.

Blower motor in engine compartment passenger firewall area, you may have to remove the cruise control servo to get motor out, very easy and straightforward job, be careful transferring the blower motor wheel over to new motor, remove lockclip first on motor shaft.

Same as other Ford problem, normal operation, it's usually the trubo-charger to blame.

The ICP code just went through this a minute ago. Reset the Computer take off the positive terminal about 24 hours to reset the PCM that should get rid of the code. It's not one to ignore I hope you have fixed the problem.
