There is a very good chance of the alternator being the problem.. these vehicles are popular for this.

1997 ford expedition makes a whining noise and pulls to the left when the 4x4 is engaged

whinning noise ?? dont know without hearing it ,pulling to the left requires a four poster lift and then a good examination with a nice long crowbar in all the silent rubber block bushes ,something is worn or perished to excess along these lines ,doesnt this vehicle require a yearly full mechanical inspection by a authorised test centre to be allowed on the road as this vehcile sounds as though it could be in a dangerous condition

There is a humming or whinning sound coming from my 1998 ford expedition while im driving. The sounds stops when i take my foot off of the accelerator.

if the sounds is comming from the rear sounds like crown and pinion is worn out , the crown and pinion in the rear diff will only hum or whine under load while in contact and when you let go the pedal there is no load equalling no noise. you can replace the crown and pinion but you do need some specialty tools like dial guages and spreaders and pinion depth guage

When I press on the gas pedal it make a winding noise and it slows down

One reason can be a slipping serpetine belt. This would make a noise and the electrical power will drop and the vehicle will cutout.

The second reason would be a transmission problem. The parts inside the trans are slipping when you put a bigger load on them. Check your trans fluid first and smell the trans dipstick to see if it smells burnt. Then check the trans fluid level.

2000 expedition pedal adjustment is stuck. Any ideas?

If the brake pedal makes a crunching noise,try flushing out the brake fluid. For some reason after flushing the noise goes away. I hope this helps,goodluck.

97 ford expedition 4x4

does the whinning noise decrease or go away when u decelarate? this is the key to a proper diagnosis. if it does, then your problem eather ring & pinion gears or related bearings (these are all in the center part of the diff.) if it does not change,the problem is in the wheel bearings, or rough tread on the tires. the former is expensive(4 or 5 hundred), the latter is not so bad(a hundred or so). u could try raising it up & supporting it under axel housing, have a friend run it up to about 40mph as u listen with a hose or stethescope to pinpoint the noise
