Replace front power seats

you try to lubricate the tracks and running gear under the seat
while it is fitted in the car
if no better
you take out the seat and inspect the mechanisim for wear

if it is a worn motor /mechanisim ..replace it

All of the following:

1. Change all fluids including coolant, brake fluid, power steering fluid, transmission fluid, and crankcase oil. I would strongly recommend increasing the viscosity of your crankcase oil at this point, and use higher viscosity oil from now on. Change the oil every 3000 miles from now on as well.
2. Replace oil filter and transmission filter.
3. OVER-LUBRICATE (really) all lubrication points on the suspension, pushing out and wiping off as much old grease as you can. Inspect all bushings for signs of cracking, wear, or chapping.
4. Perform a MAJOR TUNE-UP, replacing spark plugs, wires, and coil packs.
5. Check all brake systems for signs of wear and proper operation.
6. Re-pack all wheel bearings, inspecting them for excessive wear or failure.
7. Check front tires for uneven wear. Perform a front-end alignment if there is any uneven wear or cupping on the front tires.
8. Rotate tires, inspecting wheels for cracks or other damage.
9. Check all lights and signals for proper operation and full illumination.
10. Use penetrating oil on the battery connections to eliminate and prevent oxidation of the terminals.
11. Lubricate all power window mechanisms, door latches, door hinges, and power seat mechanisms.
12. Lubricate hood release, trunk release, and any other hinges in the vehicle.
13. Use electric-safe penetrating oil (such as WD-40) on all switches, wiping off excess lubricant.
14. Go a little crazy with the penetrating oil on anything that moves or pivots, again wiping off any excess.
15. Tighten anything loose on the interior.
16. Clean the throttle body using OXYGEN SENSOR SAFE throttle body cleaner (if you're unfamiliar with the correct procedure, look it up or ask me).
17. Replace the fuel filter.
18. Add a bottle of FUEL INJECTOR CLEANER to the tank. Don't add any more fuel until the tank is nearly empty.
19. Check the operation of the shocks/struts, and replace as necessary.
20. Check for engine codes and correct any identified errors.

That should keep you busy for awhile :) It's worth it.

replace seat switch. Only good for so many actuations, wears out!
Think about it - shocks, brakes, tires etc don't last 12 years either.

I would be checking out the wheel bearings for the problem. I would also be checking the front suspension for worn ball joints and steering end joints. Tyre wear patterns indicate unbalance-wheel alignment-shock absorbers and front end wear. I refuse to rotate tyres for several reasons Radial tyres when developing a wear pattern will retain that wear pattern even if placed on a trailer--Wear patterns show a fault for that wheel and tells which wheel and what needs to be done to repair it and lastly tyres wear in pairs so if you have a front wheel drive car why replace 4 tyres when the need is to replace only 2 front ones. Saves about 50% of the cost of tyres. The rotation theory came about from cross ply tyres and does not apply to radials except for tyre dealers profits

i dont think so but not sure.

Call the dealership and ask them how to reset the electronic on your Ford Expedition after changing the battery. Anything else is happen? Maybe like the radio wont turn on, hit the turn signals and the windshield wiper turn on. ***** things happen after replace the battery. I know what it is, it the darn wigits. GB you....stewbison

Normally when the brake pedal goes almos to the floor it is an indication of low brake fluid. Low brake fluid is an indication that front and/or rear brakes are wearing. As the brake pads wear down more brake fluid will be required in the wheel cylinders or calipers. Hint, the front brakes usually wear much faster than the rear due to the fact that the fronts due a much greater braking function that the rear. Check the front pads. Don't let them get down to the metal scraping metal stage before you change them out. This causes unnessary damage to the rotors. Look at your master cylinder on the firewall under the hood in front of the steering wheel. If the fluid level is belowhte "max" mark add fluid. Low fliud should also show as a red "brake" light on your dash, but not always.

Be sure to have tires rotated every 5000-6000-miles. Walmart is good for that.
Outside wear is normal for fronts from the turns at higher speeds.
When tierod ends were replaced it is advisable to get front end aligned. Its not impossible to replace with minimum change but if settings were done with worn parts, new parts will change it.

That is the power distribution center, the fuse box is under the dash to the left of the steering column under a cover, they are marked, the plastic cover will have FUSES molded into it.

This is simple to do once you find the battery. Remove the rear seat (pull up on the front of it to release) to expose the battery. Then remove the Negative terminal followed by the Positive terminal. Finally remove battery hold down bolt to free the battery. ALWAYS wears eye protection when working on/near/with the battery.

Note- The seat belt configuration in the seat before removing... don't forget the seat belts when installing.

Use battery terminal protector on the terminals. Thoroughly inspect the terminals for signs of corrosion. Replace as necessary.
