BOTUS, are there one or two level sensor rods? I just replaced the one in back, but wonder if there is one up front as well?

the idea of u search, is to avoid me typing the same thing for another 100 lazy owners....

one each at the front - inside top of each front tyre
one impossible to see let alone reach, hidden left rear above the park brake module - this one is usually seized causing weird behaviour as it slowly snaps off its 4 tittle legs on a pathetic flimsy metal bracket bending rather than the plastic ***** joints move smoothly over it 10 mm round ***** - you need to write and congratulate Merc for inventing 18 year old plastic that has more strength then a 20mm thick weld by a professional

do nothing and soon enough you'll have slammed the rear by 10" and you get to find out what suspension really does for ride comfort
