I have had my '03 Suburban for almost a year.

When I first got it I could tell it was pulling to the right. I was told it needed an Adler and Pitmann arms on drivers side.

I recently got all of that fixed and got it aligned too.

Recently I transferred into another position and started having to park in a parking garage. While making slow sharp turns in the parking garage I started noticing a thumping and yesterday I even heard that front tire bark.

Stopped by my local Exhaust Pro where they know me all too well and they suggested I drive it up to Big O where I had it aligned.

The gentlemen there told me he noticed the 4WD light was on Auto and that was probably what made it do that after he had already gave everything a good look beneath the truck.

Now all of the sudden those lights are changing positions and I don't really know what is going on.

It drove okay this morning going to work.

What would a typical 4 WD drive servicing and a Ride Control servicing entel?

Thx in advance.

 

Sound like you might have a bad switch for the 4x4 system the push buttons.i had the issues where it got really hot and it caused the 4x4 message.there easy to change out
