Clicking noise
I have an intermittent clicking noise that I don't like. Let me know what you think. The winner could earn themselves a chicken dinner.
Info: Some days it doesn't happen, regardless of engine temp. When it does happen, it tends to go away once the engine warms up It doesn't seem to correlate with engine RPM It seems like it's louder on the passenger side, but that's not scientific https://youtube.com/shorts/I_A7okmWenE?feature=shared https://youtube.com/shorts/b25DXgaBeoE?feature=shared https://youtube.com/shorts/zJOIYge5kL4?feature=shared Last edited by rbagley; 12-01-2023 at 01:16 PM. |

Re: Clicking noise
Couple things I would check.
bolts holding both the fan and crank pulleys alternator bearings, water pump bearing sounds like a rotational noise I even heard a fan belt make that kind of noise. Loosen the fan belt so it wont turn and start the engine and see if the noise goes away. |

Re: Clicking noise
Mmmm, chicken dinner. Alternator
Get a long screw driver, metal rod or stethoscope ($8.00 @ Hobo Freight) and put it to your ear. Touch it to the alternator and water pump to see if you can pin point the area. Be very careful. Last edited by Mid-Pack; 12-01-2023 at 01:58 PM. |

Re: Clicking noise
I would just take the belt loose and spin the accessories by hand, in my experience this will make it obvious which part is making the noise.

Re: Clicking noise
I heard an unusual ticking on my '71 GMC Jimmy K/1500. It wasn't the fan hitting the fan shroud. It wasn't the wheel spacers under my 235/75/16 tires -- I pulled those and re-installed my 33x12.50x15 meats... Still clicked.
Finally, I checked out my front Prop Shaft. A bearing cap was coming loose. I went to R&R the U-Joint, and found the double-carden joint had been beating itself to death. I took it to a driveshaft specialist. He said it was shot. New ones are about $300 - 500. I can cannibalize the one off my '67 K/10 Suburban later. For now, I pulled it, and have a ''rare'' 2WD Jimmy.
