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?
