  1. Question about afm

    If I were you, I'd get a Range V8 module and plug it into your OBD2 port to turn off AFM, for cheap insurance. And you can remove the Range V8 module for dealer service. You may notice better response and shifting with AFM turned off, and many of us noticed little to no change in fuel economy by turning off AFM. Even if you have been lucky enough to not experience the infamous AFM oil usage problem, you may still experience AFM lifter failure and/or a pitted camshaft. Most of the 2007-2013 GM 1500 folks on here say to turn off AFM as soon as you can. You may also want to install an oil catch can into your PCV system. But ultimately that is all up to you, of course. At the very least, be sure to use Dexos-rated engine oil and change the oil and filter at the intervals specified by your Oil Life Indicator on your Driver Info Center, if not sooner.

    aka RTFM. When I've had my GM vehicles in for service at the dealer and was sitting in their waiting room, the Sales and Service staff have come to get me before to look at features they/customers couldn't figure out. Yes, I am a car freak and read every car magazine and online content. And I am one to RTFM before I operate something. But it is still amazing/depressing/very troubling to me that there are people who have worked for dealerships for years have never read the manuals. And that somebody would pay $75K+ for a new vehicle and drive it for years without using 75% of the features. They'd have been better off getting a simpler, less expensive vehicle. But all that being said, I've gotten my car back from service with the radio presets changed to Mexican radio stations before, so SOMEBODY back there knows how to do some of that stuff.
  3. license plate fee

    I think you may know why. It's because y'all have to pay for those $Billion debacles such as high-speed trains that never get built, and to support CARB and your draconian vehicle inspections. Oh, and free everything for your Powers that Be and the people who vote 'D' to support them. Out here in 'Flyover Country' (that CA likes to make fun of), there are no vehicle inspections, politicians have to have at least a modicum of common sense or they soon get voted out, and hard-working people can afford to live. Our family has had as many as 7 vehicles, and still paid less annually than you and your son pay for 2 vehicles.
  4. Highway Tires vs AT Question

    Tire Rack.com says the original equipment tires on your truck were either Goodyear Wranger SR-A's or Continental CrossContact LX20's. Both of those are highway-type tread. Switching back to either of those, you would have no more rubbing, your speedometer/odometer would be correct again, and you'd get better on-road ride/handling, better fuel economy, and longer tread life.
  5. Unsettling Experience

    Sounds as if there may be a loose nut behind the wheel, or something like that.
  6. Issues with BFG K02's

    Right. I assumed he wanted to stick with an all-terrain, and he wouldn't like mud-terrains if he thought the all-terrain tires were too noisy. If he wants a highway tire, he should look at the Michelin Defender LTX M/S, Michelin Primacy LTX, or Bridgestone Dueler H/L Alenza. The Primacy and the Alenza are both TPC Spec, which means they have been tested by GM and come stock on some GM models.
  7. bFGoodrich all terrain Tire wear

    Those are no longer manufactured. BfG could not keep up with the warranty claims on them, and decided to throw in the towel and quit making them, when they came out with the new K02.
  8. Depends on how you define 'better'. Filtering out smaller particles usually means more restrictive flow, which on my truck, means the Mobil1 filter causes much worse AFM lifter noise and piston slap at startup, than the AC Delco factory filter.
  9. Issues with BFG K02's

    Happens a lot when tires get older and the oils in the rubber start to dry out. Especially on all-terrain tires, which have a tread pattern that runs noisier to begin with. May be exacerbated by the alignment being off. Mine was toed-out from the factory, which caused the inside tread blocks to wear a little funky, which led to a whomp-whomp-whomp sound (but surprisingly, not much vibration at all). When the rubber starts to dry out, a lot of times you'll get small dry-rot cracks, especially down between the tread blocks or around the tire bead where it meets the wheel. In my experience, those little cracks are just superficial--they just look bad but don't hurt anything in normal use. A lot of folks (that have enough $) replace their tires every 3 years/30K miles or so, because of this. I don't have a lot of $, so I turn up the radio volume and run the A/T tires clear down past the wear indicators, unless they get to vibrating too badly. If you need a 10-ply tire for towing, in that stock size, you're stuck with the BfG KO2's. The Nitto Ridge Grappler is available in an XL load rating. Or if you can run a P-rated tire and want a quieter on/off-road all-terrain tire, go with the Continental Terrain Contact A/T, Yokohama Geolandar A/T G015, or Bridgestone Dueler A/T Revo 3 or such.
  10. Breather hose replacement..

    ACDelco.com online is showing (under Hoses, Other) GM Part numbers 12597774 and 12609373 as still being available from GM dealers. Those are the 2 PCV valve tubes with the connectors on the ends, one "dirty air" and the other "fresh air". Rockauto.com has them listed on their website for $5.43 each + shipping.
  11. Front air dam removal?

    How do you like those Revo 3's?
  12. bFGoodrich all terrain Tire wear

    Goodyear Duratracs. Or Bridgestone Revo 3's, if you're on the highway more than off-road.
  13. What is GM thinking? Unfortunately, seemingly the same thoughts as most of the manufacturers today--lie, cheat, & steal--pump out defective product as fast as you can, and take the $ and run! I can't believe our society has become so passive that $60K+ defective vehicles are accepted as a 'normal' disposable item to be pawned off on somebody else and replaced every 2-3 years!

  15. Holy smoke. Already had to have a master cylinder replaced, on a brand-new Trailboss? Does GM have ANY quality control anymore??
