My 2 right wheel bearings were replaced at approx 80K Mi.
At 100K Mi, my two left wheel bearings are going out.
The infamous shutter of the transmission has been going on since approx 75K Mi.
I too have a 2002 with the same problems.
I too have had the same problems with the transmission. I'm told it will cost $1600-$1800 to fix the problem. I have 99,000 miles on mine now, the "shudder" began around 60,000. If I had only known before I purchased this vehicle, I wouldn't have. Will it cause more damage to the transmission?
I have had problems with the transmission in my 2002 mercury mountaineer since 32,000 miles. First, it "lost" first and third gears, then a part was replaced. That time they had my car for a month before it was repaired. Then at 84,500 more problems with the transmission. I bought a rebuilt one to the tune of $3,200. At the same time they had to repair the read differential, and replace the wheel bearings on the back. Now, after less than 7,000 miles on the rebuilt transmission, I was left stranded on the side of the road with my car not driveable again, you guessed it transmission!! It is in the shop now, I will let you know the outcome. I at least purchased a warranty with the rebuilt transmission, so they had better replace it with that! I love the way this car looks, but otherwise I will never buy another Mecury or Ford product again!
I too have had the same problems with my 2002 Mercury Mountaineer. This is the second transmission that has been replaced (rebuilt). I bought is brand new, the first transmission went out at 75,000 then again at 125,000. It's a piece of trash!!!
