I've had it on mine since the truck was new. It slowly got worse but improved after I tightened the belts. It's back quite a bit more now so, at 50k, I'll have to look in there and see if the belts are in good enough shape for another adjustment or if it's time to replace them.It does have A/C - I think that would have been a deal killer in here in South Carolina!
Now that you mention it, I did see one on cars.com without it - I think the truck may have been in Wyoming or somewhere like that...
What's funny is that I see another one that looks identical to it in my parent's neighborhood sometimes. I guess it's someone that visits one of their neighbors. I wonder how many of them were made?
Speaking of A/C - mine has a belt squeal issue with the air conditioning. I hear it chrip sometimes when the compressor cycles on and off, and on really hot days the belt will squeal pretty loudly for a few seconds when taking off from a stop.
I assume I just need to put new belts on it, but I thought it was interesting that I found several mentions of this specifically on the '04 model year when I google searched it. Have you had this on your '04?
Good job on the wipers :excellent:
