Question Ride Height and Tire Damage

I took my GL450 in for its 1st checkup (1500 miles). The front tires were cupping. My service advisor explained to me that I should not drive my vehicle even at low speeds while in the "raised" height position. He stated that it throws the front end out of alignment (camber) and causes the tires to cup. They actually had to rotate my front tires to the rear in order to prevent more wear.

Has anyone else been told this? It makes no sense to me that this would be an issue and not be plainly stated in the owners manual.

I personally like the look of the vehicle in the raised position much better. It looks too much like a mini-van in the lowered stance.

Wouldn't you have to drive for a very long time for it to wear down your tires?

And it'd be hard to keep the GL in "raised" mode because it drops once you hit 40mph. Sounds like BS to me.

"Even at low speeds".......what are they saying? If the vehicle "should not be driven" in the raised position, then what the heck is the raised position for??? Something doesn't make sense here.............

The raised position is to provide additional ground clearance for the vehicle in rough terrain. The normal riding position is not lowered, it is normal and designed to ride in that poisition under normal driving situations. It will also lower automatically to provide better aerodynamics at higher speeds.

I don't mess with ride height but...

I leave the ride height function alone. However, the GL320 seems to raise and lower itself as it wishes. Does anyone else have a similar finding?

While the vehicle does look better raised, I do agree with what NJ said. Another factor for height dropping at higher speeds is to ensure that CG stays low to reduce rollover risk.

I also leave it alone; no fording rivers for me. But at stoplights or in the garage, my GL will start dancing up and down at it's leisure (not really, but Airmatic does seem to have a mind of its own)...

Do you have any idea how much money people pay to make their cars dance up and down??? And, you're not happy that it's standard with GL?



Those engineers at MB, they are always thinking. They might not be thinking the right thing but they are always thinking.
