FOGHORN
Guys,
I've seen many threads hitting around this problem, but not quite addressing my exact symptoms. My '01 F-150 2WD, XLT has a foghorn sound comming from the left front side at idle after the 4.6L is warmed up. It goes away with an increase in engine RPM and is unnoticable at hwy speeds. I have no codes (I have checked w/ my code reader). The service desk guy at the stealer said it is my abs pump going bad (I figured it was a pump of some sort, my 55 packard PS makes the same noise when almost empty-the system leaks). It also appears this is a stealer only part, and going to cost 6 or 7 benjamins to buy and probably another 5 benjamins too fix. Is ther a less expensive alternative?

Get in there and listen/find out what's makng the noise, then figure the expense.
The costing your giving is way too high for a power steering pump to do the repairs unless your bound to use a dealer for the work..
Check ROCK AUTO for a pump..
If the noise changes as you move the steering wheel then that's it.
But if not, it's something else.
Good luck.

After much testing, the PS unit is not the culprit. I am however experiencing a lot of brake fade. Is this a symptom of the abs pump going out in addition to the foghorn I keep hearing?

Check your IAC valve (bypass). I have the same issue and more than likely it's that. You can take it off carefully and then clean it with some good carb cleaner. It gets gunked up and the spring inside may seize a little. Clean it and reinstall and it should be good to go.
