I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

SOURCE: 1997 GMC Sierra Ignition Switch Replacement

take off the cover on the top and bottom of the steering column just behind the wheel. pop the tilt lever out simply just by grabbing it and give it a good tug. then once you have the new switch and you get in there your going to need an inverted torx socket to remove the small bolts that hold the switch to the column. do not move the gear on the new switch make sure it lines up exactly as the old one did!!!!!!!!!!!!

Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem

Remove or disconnect the following:

Air outlet duct Coolant Inlet radiator hose from the water pump Upper fan shroud Cooling fan and clutch assembly Drive belt Radiator outlet hose from the coolant pump Surge tank hose Heater hose Water pump



DO NOT use cooling system seal tabs (or similar compounds) unless otherwise instructed. The use of cooling system seal tabs (or similar compounds) may restrict coolant flow through the passages of the cooling system or the engine components. Restricted coolant flow may cause engine overheating and/or damage to the cooling system or the engine components/assembly.
Install or connect the following:
