The crankshaft pulley bolt may become loose or break causing loss of power steering operation and other related engine accessories. Some of these vehicles may be involved in a recall for this issue. Our technicians tell us that an updated bolt may be available. Replacing as necessary and properly torquing the crankshaft bolt will commonly correct this issue.

    Bolt spun off and so did the pulley..I put it back together, and it was wobbling...and spun off again.
    This was due to a BAD A/C Compressor...The pin broke as well, so I have to get a new one...
    I think that others are haveing the same problem because the compressor has froze up..
    The engine tries to run, but the pulley on the compressor will not budge...therefore the pully spins off the Bolt.....
    I unhooked my A/C belt, and NO MORE ISSUES>>>>.
    I love my montero... It has been very reliable...
    The only other issue has been the front dif. case leaks.... I can bet that EVEYONE else has the same issue.... it doens't need attention, other than add some diff oil every year or so...

    I am now off to get a crank shear pin...

    Montero sport has started to make a clacking noise in the front end. On further inspection mechanic states that the crank pulley bolt, has come loose. He confirmed that he has repaired a lot of these cars for the same problem. Sounds much like a train clacking on a railroad track. I am having a noticeable problem with steering, harder to pull from side to side.

    I have had the pully repaired 4 times in 3 months, Bought a pulley,shear pin and bolt I have had the bolt replaced 3 time. this last time I went to start the car the battery and brake light stayed on, sure enough checked the belts sure enough again. I paid 5500. for the car 6 months ago the car has been broke down 3 months out of the 6. I thought I was getting a good car. The car has suck every penny I have. Im a single Mother thought a good dependable car the only thing I can depend on it wont leave my driveway. Did I mention the 02 sensors. We spent last summer without a car. Sure hoping this summer would be differnt. Only solution is try to sell it to by another car. no way will I get back what I got into. this been a expensive learning experiance. I will never own another mitsibichi again. I wish I could say I love my car. My nick name for the car is (makes me so bitchie). I am stuck way out int he country with no car and a 5 year old daughter. Anyone want to buy my headache. I dont have the money to fix the car again.

    I have had this happen twice, almost exactly a year apart. Once was in the city, and the other time one the highway. It is an expenseive fix either way, but the second time we were way away from help on thighway with a pregnant wife, pulling a tent trailer - that was really bad and VERY expensive!!Don't like not being able to trust the vehicle anymore.

    Same problem happened to me twice in a 6 months interval.
    First time, i took my car to a mechanic and spent about $1,500 on it. This time they asking for about $4,300. So i took my back back, manage to remove the pulley. i realized that the shear pin was broken.
    Can someone please tell me how to replace the shear me?
    You can email me a josuenduwa@gmail.com
    Thanks

    my crankshaft pulley came loose but didnt break. i noticed something was wrong once the battery light came on and the power steering went out. the belt had slipped off and there was a ton of play in the pulley. i towed my car to my house and am currently working on loosening the bolt and inspecting it for damage. not too pricey so far...hopefully i get lucky...i just got the bolt out now and the threads were pretty damaged. an impact wrench helps and if it gets to a point where its not moving try tighten then loosening the bolt. the working back and forth seems to get it out.

    Crankshaft pulley bolt broke on me going down the highway. Good thing I realized something bad was happening and pulled over as soon as it was safe. The vehicle started to overheat immediately.
