ac noise

I've got the throttle-lift-grind that regular cab owner's have often discussed on this forum. I don't use the A/C often, but when I do, this grinding is 10X louder.

Don't know what the correlation is. I've been under the impression that the grinding had to do with the slightly-off angle of the driveshaft. The A/C making the grinding louder implies clutch or transmission problems instead. Maybe it is the TOB . . .

 

i'm in the same boat. with the ac on it's such a strain on the 4cyl the throw out bearing rattles. press clutch in rattle goes away

 

maybe you just have noises in your head and its you that has weird shat goin on

 

My 09 that I drive at work has been doing this for the last 20K that I have had it. It has 53K on it total. Probably been doing it since new. Don't know for sure, I "inherited" it at 35K.
