2007 ram hemi 4x4 AC vibrations
Hey I have a 07 hemi 4x4 quad cab and the truck vibrates when the AC compressor kits in. I've looked under the hood a ton of times and can't seem to understand why its happening. It just started a few days ago after being out in the woods. I washed to motor a few times thinking maybe some mud got somewhere but it doesn't seem to help. its only when the compressor turns on. Truck only has 54k on it! any help would be great. I searched everywhere and it seems to be common in diesels.

I have the same issue!!!!! i think it's just mud/dirt in the bearings or whatever of the AC condenser fan.

I found a good YouTube video of a way to remove
and replace just the fan unit without having to empty the coolant system. just haven't done it and am getting used to the vibration. all cars/trucks do it, just ours is worse i guess

Can you see the clutch fan engage?
If a small branch, mud, or stone lodged in the compressor clutch it would certainly throw it out of balance causing a vibration.
