i found it just laying there at the front of my car between the radiator and engine.....and my car does not run right now ......just drove it last night and today i tried to start it and it wouldnt start but it would turn over.......when the battery is hooked up there is a continous buzzing sound, even when the car is turned off.......if i take the brake light and healdlight fuses out then the buzzing stops......but it wont start or jump off.....and nothing is wrong with the battery. though when i was coming home last night it did seem the lights getting a bit dim but i didnt pay much attention to it.....but i had the batterry checked and everything....not the battery

It would have helped a lot if you would have given the make and model of your car, but it looks like the housing for the serpentine belt tensioner.

those aspects are consistent velocity joints. On front wheel force automobiles there are 4 complete joints, 2 according to ingredient plus a force axle. The broken one on your great image will fee $sixty two.00. i'm pertaining to a sparkling re-synthetic 0.5 shaft, the appropriate, good fee and least complicated to swap. It takes an hour to 2 hours to swap at any broking or self reliant fix shop.
