What is the drive cycle for a 2005 Mercury Mountaineer 4.6L AWD.

SOURCE: 2003 Mercury Mountaineer no heat

no you have to remove the vent between the hood and the windsheild its on the out side of the car it sounds like your freshair vent is stuck open

SOURCE: 2002 merc mountaineer awd wont come out of awd

If the vehicle is made to be a AWD you cannot get it out of AWD unless you take off the front drive shaft

SOURCE: 2005 Mercury Mountaineer rear end whine, how hard to fix

Before you do this you might want to try fresh gear lube. On Ford products they use a synthetic additive in the rear and not in the front 4x4 axle.
The next thing would be to determine if it is a wheel bearing or a pinion bearing. You have to pull the axles and eliminate them as the problem. You might get lucky and not need to do the pinion.
The technical part of shimming the pinion gears with replacing the pinion bearing is about the worst part of the job. You won't know about the gears until you see them. You will need extra shims on hand.
It is a moderate job for two people. If you have all the parts it can be done in a day.

SOURCE: My 2003 Mercury Mountaineer V8 AWD transfer case

the problem is the chain inside strechs, could cause case damage, it will soon break and then truck wont move, depending on how bad it is you may be able to drive a bit more, threres just alot of strain there because of it being awd, if it is noisey it doesnt have to be replaced just fixed,good luck.

Testimonial: " Thanks! It does make noise, a clunking sound when I back up and cut the wheel to the left or right. The tires skip also. "

SOURCE: where is 2005 mercury mountaineer fuel filter

Fuel filters can usually be found on the drivers side under carriage about middle of the vehicle. There should be a canister type filter with 2 metal lines connected to it. One on both sides of the canister. you will need to disconnect both lines and the bracket that holds the filter in place and install the new filter. I do suggest that you remove the fuel cap to try and relieve some of the fuel pressure built up in the lines before disconnecting the filter so you won't be sprayed too much with fuel. If you have any other questions please do not hestitate to ask.
