Hello. Just checking to see if it is common for GLS to have air spring leak just like GL did. Spring looks exactly the same what MB was installing on these vehicles 10 years ago.

 

The 166 airbags seem to be more robust, on the surface they last longer, than the 164's but they will still suffer the same fate. MB is consistent but that is good and bad. How many miles do you have on your GLS?

 

My rear air springs leaked at 80k miles.

 

The ones from Arnott seem to have more longevity than the stock airbags.

 

95k. I think around the same mileage I replaced the second air spring on the GL. Arnott springs have been flawless so far.
