    How much better is the 14B 9.5" SF really?

    So I've been saving and scheming for the next big upgrade to my '97 K1500 Suburban, 3.73. Ages ago I sold myself on the idea of an axle swap and now I'm getting cold feet. Let me know what you think. My truck is increasingly becoming less of a daily driver and more of a weekender. Lots of...

    Catastrophic Power Steering Leak - Other Damage?

    One of the cooler lines sprung a significant leak last weekend about 80 miles from home. What do ya'll think - can the PS pump survive being run that long dry, or would it be in the back of your mind that it might give out at any minute? It was mostly interstate driving but it definitely made...

    Weak Tow Hooks? Do the tusks fail?

    I was talking with a grizzly tow truck driver the other day at a trailhead and he points at the front of my suburban and says "Those tow hooks are notorious. Be careful if you ever have to use them." I've pulled friends and been pulled out myself a handful of times and never had a thought...

    Water Pump + Throwing parts at this truck.

    So I’ve procrastinated replacing my water pump all summer and have finally found some time, money, and motivation. I expect to have the truck for the next 100k+, so what else should be freshened up while the front of the engine bay is opened up? This truck is my daily and it takes me deep off...

    Good/Better/Best Trans Cooler Hose Connections?

    So my 205k mi suburban put me on the side of the interstate yesterday. A trans cooler line came off at the oil cooler. It's an aftermarket cooler with rubber hose pushed onto the barbed fitting pictured below. Obviously I didnt tighten the worm screw hose clamp enough... Guess I was afraid the...

    My transmission's skirt keeps getting shorter -- showing its last legs. 1997 Suburban, 202,000 mi I was way out there on a BLM service road this weekend, shifted 3->2 downhill at ~40mph and...scary sounds (a moment of grinding followed by it sounding like it freewheeling? loud whirring)...

    Any luck with A/C Sniffers?

    I'm about to start chasing a slow-ish AC leak and am considering buying one of these leak detectors. For $25 on amazon, I can't get burned too bad, but I'm amazed that they cost either $25 or $250! Previous owner has records of his shop looking for the leak via UV on four separate occasions...

    Junkyard Alternator Upgrade

    Hey All - I was in the junkyard yesterday pulling seats out of a 1999 Suburban 2500. The thing was immaculate. I'm headed back this afternoon for another go. Wondering about the alternator - its looks stock and beefy. I haven't looked at model numbers/amp ratings but it is physically a lot...
