I went out to introduce the truck to mud this morning and came back with a weird vibration. I didn't find any threads that has this problem so im lost.
Only when i turn the ac on the whole truck will start to vibrate (like an xbox controller but not as dramatic) It will stop after, im guessing the ac clutch stops, about 30 seconds after I flip the switch to off. Any other time its normal. Ideas?

 

Check for mud caked on anywhere especially around the ac clutch. When I buried my truck in clay a couple of years ago, the truck vibrated violently like the driveshaft was about to fall out. As soon as I cleaned the caked mud out of the wheels, the problem went away. The wieght of any mud could cause the part to run slightly unbalanced and ause vibration.

 

Where's this "mud" you speak of? I just see a little road dust kick-up. :P

Before reading about the A/C thing, my first thought was mud in one of the wheels causing it to be temporarily out of balance. Guess that theory is shot, though... I don't know. Hope it works itself out, though.

 

I have seen people go mudding then get a weird vibration afterwards from mud getting clogged somewhere and then they didn't clean it out but I never heard it having anything to do with the A/C

 

Yeah make sure you get the mud off the rims and tires, that little mud left on the rims can throw off the balance. Happens to me all the time

 

Mud here is Georgia red clay and that ive heard can work its way inside the tires if you bog deep enough

 

Take it to a DIY car wash and get busy. Just don't be the guy that leaves all the mud in the bay! I hate that guy!

 

You say it goes on with the a/c and for about 30 seconds after you turn off the a/c ? Sounds like you have mud on your a/c fan.....which is electric and only runs with the a/c. And for roughly 30 seconds after you turn the a/c off. Might want to look at that. Could be mud or a cracked blade.

 

Its barely even muddy lol.

 

I took it to the wash today and focused on spraying the ac portions of the engine bay most. The vibration is gone and everything is back to normal, im gonna have to get used to more mud going in the engine area because of the bl. Thanks for the imput!
