Maintenance/Repairs

Concerning my recently purchased '99 GMC Sierra 1500 2wd 4.8L…

There is a seemingly undiagnosable, not that noticeable, rubbing noise that seems to come from the front passenger wheel - one rub for every revolution of the wheel. It is fairly subtle and can be felt (subtle) in the steering wheel between 30mph and 45mph. I don’t think a lot of people would notice it and anyone that did would probably just turn up the radio at this point. After all, this truck has a very solid drive train and runs amazingly smooth for its age and mileage (172K)

Here are the repairs I have made that you might be about to suggest:

New front bearing/ hub assemblies on both sides within the last year. No play in any of the wheels.

New tires from Firestone within last month.

New tie rod ends and alignment.

New rotors, pads, and flex lines on front. Refurbished caliper on passenger side front.

New pads, calipers, and flex lines on rear. (one of the calipers had seized and I thought I had finally found the problem… not.) (one of the flex lines was the wrong part and was rubbing up against the rim… I thought that was the problem… not.)

Here are the things you are about to suggest I check:

Transmission, rear axle bearings, etc checked out by my trusted transmission shop.

Wheel well shields are firmly attached.

Things I haven’t yet fixed because I have spent so much time and money trying to fix this noise: tail pipe bracket, evap emission solenoid assembly (thanks GM for making parts like this as if designed just to aggravate drivers with warning lights.) , blower fan resistor thingy, crappy door latch.

Where should I go from here?
