Review on 🔧 Front Suspension Air Spring Shock Strut for Mercedes Benz W164 X164 | 2007-2009 GL320, 2010-2012 GL350, 2007-2012 GL450, 2008-2012 GL550, 2010-2011 ML450 | Part Number: 1643204513 1643206113 by Troy Hamilton

Replaced the front air shock which had been leaking for a while and after installation the 2012 GL450 would not rise to the normal ride height. Checked the existing pump and there was hardly any air movement. Replaced with this pump along with the filter and now the car starts normally. The only difference I can tell is that after the pump has stopped, there is a loud flushing noise at the pump inlet, as if air is momentarily escaping. The normal one did not make such noises, but this does not affect the functionality. **** Pump update died after 6 months
