Hello there,

I am a new owner of a beautiful 1998 Suburban, have a problem and need
help - as there aren't any Chevy dealers here in Slovakia


The car runs without any Problems as long as in 2wd mode. No noise, no
nothing, just enjoying the ride... The switching into 4hi or 4lo as
itself also runs without any problems, blinks 3 or 4 times and it is
engaged. The real problem is, when I try to move the car from a stopped

position. The front axle acts like I would have my parking brake on,
the car needs power to become moving, after it reaches about 10 km/h
everyhing is fine and the car is driveable without any problems. During

the acceleration until 10 km/h the front and rear wheels somehow slip
for 1 or 2 seconds. All of this is mostly noticeable when steering to
the left or right from a stopped position. When switching to 4auto and
starting from a stopped position, the car sometimes nearly "jumps" does

a very fast movement to the front and stops afterwards when trying to
accelerate.


Can anybody tell me where to look and what might be the problem ? I am
very helpfull for ANY hints as there is NONE Chevrolet dealer or
service in the whole country :-)


Thank you.

There is no problem. This is normal. You should not be using 4x4 on
dry pavement unless you want to pay for major repairs. Read your owner's
manual.

Well, if it is normal, I am not so worried anymore.

But... the question is, why when I turn on the 4x4 auto function (on
dry pavement) the whole car strangely accelerates ? The whole car acts
like if I would give full gas and full brake at the same time..

That I'm not sure about. You might need to have it looked at for that
reason only. But everything else is normal. Good luck.

With a vehicle in 4 wheel drive your front wheels are trying to turn at
the same speed. When you turn on dry pavement one wheel is actually
turning at a different speed. That is why you feel a loping motion
and maybe some noise. It is not good to do this very far but indicates
that you are actually in 4 wheel drive. If you are ever unsure if you
are ingaged or not this test will definitely let you know. Also, when
you put your vehicle in 4lo in particular your will feel a different
response to your accelleration. The biggest reason for that is you are
in a ultra low gear. Stepping on the accellerator you might feel like
it is lurching forward, rpms will even encrease just standing still,
but I would think that everything is opperating normally on your
vehicle by your description.
