How do I engage 4 wheel drive in a 1988 Wagoneer

If this is Quadratrac it is a full time four wheel drive. High-low range was an option in that case. This is a vacuum controlled unit, that is very picky about having the right kind of fluid put in it. If you don't see a switch or a lever it might not have low range. There may be an owner's manual in the glove compartment, you never know.

The Full Size Jeep Association web site might have useful information too.

Tell us what you have by the fifth number in it's VIN:

Earl,

I didn't mention, but there is a dash mounted switch for 2 wheel drive and 4 wheel drive and a floor mounted lever for low 4 and high 4. When I switched the dash mounted switch to 4 wheel and lifted the lever to 4 low I don't detect any discernible difference. Am I supposed to be stopped and put the transmission in neutral and then lift the lever for 4 low? Boy o boy am I confused.

Heh, if you're confused now how are you supposed to take care of it after you buy it? Plenty of Suburbans and Tahoes on the used car lots. I got a nice three quarter ton a few years ago with an Owner's Manual that shows how to shift into and out of four wheel drive, in case I forget.

Are you a AAA member? AAA has auto diag clinics that run several tests on the car to see what's wrong with it.
