    '04 Yukon XL 2500 autoride shocks source?

    Curiouser. Shock Warehouse has no database for a 2004 with rear non-air autoride shocks. WTF? Edit; CK5 forum seemed to know this is standard on the 2500 with possible air ride on top SO. Looks like not much option but to convert it.

    '04 Yukon XL 2500 autoride shocks source?

    A hundred threads, but most old or airbag related. I have 109,000 miles and the rear shock bodies are pretty rusty, though no sign of leaks. One tire bounces pretty hard at 55mph, so I know somebody's dead... Is there any source for stock or aftermarket electronic shocks, or am I forced to...

    400th 'front axle not engaging' problem

    The axle harness has a connector on the inner fenderwell just in front of the brake lines. I peeled the harness back where that connector goes into the larger harness to the frame ground, no evidence of a splice. <shrug> lots of gymnastics for something so simple, but that's one of the downsides...

    400th 'front axle not engaging' problem

    Neither the original nor replacement actuators extend. I checked, have B+ and ground at actuator plug, but I'm alone with no helper or DMM available so can't test signals. Possible control module on the buttons? Will 4x4 DTCs show up on my cheap OBD scanner?

    First post, wiring?

    2004 Yukon XL 2500, 8.1L, high options. Just acquired it, bought it for Mom ten years ago. She quit driving, Sis-in-law drove it for the past 6 or so. She's fat and climbing in she tore off the driver's side A-pillar cover, no damage but there's a small harness with 4 wires; black, white, red...
