The crank sensor is located behind the harmonic balancer on the front of the crankshaft.

SOURCE: 2008 Chevy Impala SS V8 , is making grinding noise during left turn and acelerating. Thought it was left hub bearing and had fix noise is still there. Any ideas?

sounds like something in the driveline. if wheel bearings are good it could be brake caliper making contact with rotor, axle bearings , or the transmission may be failing. if it does it worse in 1st gear then its more likely to be a transmission problem. check both sides though. often noise and vibration can travel from one side to the other. also check your tires for knots or cuts, flat spots or heavy brake dust on the wheel. tell me what you find. hope this helps.

The crankshaft positions sensor is located behind the crankwheel on the passenger side of the engine. In order to replace it or at least examine it, a person would need to remover the crankwheel with a puller that can be rented out at Autozone. Just ask for a harmonic balancer puller. Remove the front right tire and place firmly on jackstands. The crankshaft pulley WILL NOT loosen by just turning the bolt. This is a two person job. Caddycorner to the starter, there is a small plastic plate cover that covers the driveplate/flexplate. Remove the two bolts and pull the cover off. Have one person position a screwdriver into the ring gear teeth and have another remove the pulley bolt. Its EXTREMELY TIGHT and the best way to remove it is with a large rachet and a breaker bar. Once the bolt is removed, take the puller and position accoridngly. The threaded holes are not on the surface but inside the pulley itself. Place large bolt in center of the puller and place the pointed or flat tip on center of the large bolt and place. Take three very small screws or bolts that came with the puller and position all three in place. Once all this is done begin turning the bolt in the middle of the puller clockwise. This will take alot of arm strength and anywhere from 15-30 min to do. Once the wheel has come off, carefully pry off the sensor cover which is another piece of plactic. Once the cover is off, carefully remove the sensor and examine or replace as needed. Installation is reverse of removal. Hope this helps
