Air Suspension Issues

Following a lot of challenges with my GL450 in the last 6 months (see http://www.benzworld.org/forums/gl-...rg/forums/gl-class/1586053-living-gl-nightmare-engine-transmission-service.html ), I have a new problem that is coming up and would love to get your feedback on this

:crybaby2:

The front right of the car starting to lower itself sitting idle in the garage a few weeks ago, first hardly noticeable, then more.
Then one could notice it when driving and I started to get notices 'Compressor overheating'.

I visit my friends at MB and sure enough the answer is "this is normal, the seals of the air suspension need to be replaced".

What sounds like simple thing (how expensive can it be to replace seals?) gave me the next shock. Parts $1600 plus installation and tax - total more than $2000 - PER WHEEL!!!

Of course I am getting the story that this is normal, that the heat of the climate is at fault and 'I should be lucky that it lasted 50,000miles'.

Have you ever heard of such a thing - that after 50k miles one has to replace seals for $8000 for the suspension??



Anyone had these issues?

Yes, got the same issue on front passenger wheel. Except mine wouldn't even rise when driving... Had to replace it, but luckily under extended warranty. This, to me, is obviously a design flaw. Mercedes-Benz parts should not systematically fail after 50,000 miles or about 80,000km in my case. If they do, then this should be covered somehow, under drive-train warranty... Cuz it seems they were designed this way... If it's so normal, shouldn't it be listed in the maintenance schedule? This is a really disappointing side of the GL

Arnott Inc. Air Suspension



Unfortunately this is normal for the GL. The air springs are very small for such a big heavy truck. The air pressure is too high and this causes the air spring bladder to wear out quicker than expected. The rubber bladder dries out and begins to leak around 50K miles. We have new rear air springs and remanufactured front shocks. Our parts have a lifetime warranty so we will cover the part as long as you own the truck. We only use German made Contitch air springs on the GL to help with long term premature wear. Our new rear air springs will cost you around $300. for the pair, and a reman front air shock will cost you around $300 each. We also offer a 10% discount on all products. Look for our discount code posted throughout the forum.

Please let me know if I can answer any questions.
Thanks
Adam
