how is the fluid level and condition?

no metal flakes suspended on the fluid?

The Mountaineer uses a fully automatic AWD transfer case instead of traditional 4 wheel drive.

Wrong place to ask

This is a chat room

You ask those questions at a repair shop
after a proper & though exam of the truck

The cost can only come from the merchant you chose

You don't know what your going to authorize or be willing
to fix & pay for

there is a emergency brake shoe inside the rotor and there is a brake pads too

take off wheel and hub use hammer tap them out from front replace / insert new one in hole tap back in u will have to turn axle to desired location to get new one in

Take the wheel off,remove brake drum,hammer stud through axle hub,pull new stud through hub with lug nut until seated against axle hub.

Hello, They have the old Starwheels in them. Just take off the rubber plugs and adjust the Starwheel looser. Check out the top of the rear brakes where the Emergency cables attach to the mounts.

When the Emergency brake cables adjust, they draw the brake mounts tighter by pulling the cables. Even when the Starwheels are loosened, the tops of the brakes can still be too close to remove the drum/rotors. You may have to backoff the adjustment nut in front of the split for the right and left Emergency brake cables. This will give you slack at the rear wheels. You may have to force the brake cable back into each wheel.

In some cases, the spring reel under the dash will need to be released to allow for even more slack. Make sure you start oiling the rotor around the wheel studs and the center of the hub.

Good luck on this repair.

Replacing a transmission can run $1,800-$3,500
I'm thinking closer to $2800 for you because it is a more sophisticated AWD model, perhaps more. Hope that is informative enough for you.

Please rate me, thanks!

Depends I had a whole new used one put in for 1300...I had the front diff replaced 2x and the front driveshaft 2x a Drive shaft by shaftmaster is about 340. Some type of frame tweakage that throes it off. Always make sure you have the same tread on your Mountaineer if you have AWD.
