Question
Any help on a 2000 Silverado with the ABS light on?
Fabtech 6" Suspension lift, 315/75's, 3" body lift.
Is there something that goes on with lifted trucks and the ABS lights?
HELP!
Thanks


Answer
Dan,

I'm not familiar with the ABS system on the Silverado, but many of the newer vehicles have a sensor located in the rear differential, which sends a signal to your computer system through a couple of small wires.  I have seen these wires break on occasion, sending an error code to the computer.

The lift should have nothing to do with the ABS light, unless a wire got pinched or broken in the installation.

I would suggest that you purchase a repair manual for your rig, and review the ABS section.  A Chilton's or a Hayne's manual can be purchased at most auto parts stores for $20.  They have a lot of information on basic trouble shooting, and repairs, including a list of special tools that may be needed for a specific job.  These manuals are designed for a year or range of years for specific vehicles, and are invaluable if you are planning on doing any repairs, or maintenance yourself.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
