    1A Auto wheel bearing.

    Wouldn't suggest you drive to the store in the truck to get the new wheel bearing. Also check the ball joints on the suspension and check the front drive or half shaft cv joint boots for cracks and further check the halfshaft diff seal for leaks (and the fluid level). You are in this deep, fix...

    AWD vs 4WD

    Yes, the AWD is on when turning. It's AWD and it's proportionately always on. Your other truck, is it equipped with a 4 button 4WD selector, with an AWD option? If so equipped, you can select 2WD and disengage the front axles allowing the wheels to turn at a sharper angle thus reducing the...

    Feels like I got hit in the REAR when I brake

    Is there an associated noise? How long is the delay? All brake delays feel like they can be measured with a calendar but actually its micro-seconds usually,anyway, explain your version of "delay". Are there any signs of a bent or binding shock? Safe to assume you put your fancy pads on new...

    Feels like I am driving over rumble strips.

    If you have large performance tires 20's, 22's, the obnoxious 24's or larger, look at the tread on the inner part of the front tire. Run your hand along the tread at the inboard shoulder and see if you feel repetitive cupping or scalloping. This is usually due to tired shocks and misalignment...

    The Unexplainable, Unresolved issue an expert LS builder and Dealership can't figure out

    Someone nailed it with the washer lines. I was a GM tech for many years and left in 2015. I can't remember if the front washer lines run under the cowl (the grill at the base of the windshield) or not, models vary. I think they do, if so, a leaky joint in the fluid pipe system may still allow...

    AC PROBLEMS

    There are a few easy checks, someone mentioned ensuring the compressor is spinning and clutch is engaged. Place your hand on the drier (the cylinder thing in the ac line) and it should be cold to the touch, like 36-40F. You have not measured the high side pressure or checked your fan clutch. If...

    Troubled 03 yukon

    There is an important ground for the pcm on the passenger rear of the engine. It corrode inside the jacket in and creates he'll. Give it a modest pull not a test of manhood and if it stretches or snaps as many do, cut back to clean wire, add fresh similar size wire, seal your joint and reattach...

    how to match Bose components

    I think you may have hit on the problem, I will look at the SPID label and follow up with this info. The radio is the unknown variable other than it came from an '03 Sierra and it is a single cd Bose, not a UC6 6cd Bose as originally equipped in my vehicle. Good link, thanks ---------- Post...

    how to match Bose components

    I bought my 04 Yukon XL used last summer. I moved to Ontario from Florida and needed a "winter vehicle". Foolishly the Bose UC6 radio was removed and replaced with a Kenwood deck. I inspected the console and found the amp and subwoofer, harness, connectors were all present and intact. I bought a...
