Finally had the torsion bar bushings from Boschbrakes installed. The old ones were definitely broken.Thanks to MB deciding to use inclinometers rather than a linear measurement like BMW, what you (and everyone else) is asking for apparently does not exist. Since no one on this board owns a new W163, we can't measure one either. I would be extremely surprised if MB set them up from the factory with the front higher than the rear, therefore it's likely that if you set the front no higher than level with the rear (with a full tank of fuel), it will probably be closer to where it's supposed to be than it is now. It sounds like the front end on your ML has drooped quite a bit. With a full tank of fuel, wearing OE tires and with the torsion bar bushings apparently not broken, the front end on my ML is ~5/8" lower than the rear. That's probably pretty close to where it's supposed to be, but possibly a bit low. When I change the torsion bar bushings (probably in August), I'll let you know if they were broken.
You will need to turn the nut "clockwise" which will now raise the suspension as gotca stated. Place a tape measure or stick into the hole next to the nut and measure and record its depth each time you adjust it, so you can gauge what firmness is to your liking.so for the non-mechanics here, Im seeking to set front suspension a little harder, now is very soft and every time aI go thru a small bump, front goes all the way with a "thump"......, so shall go up or down for harder suspension with Tbar???
I think it was exhale part that hit me first time.:|The bump is a bushing problem.....
Could be ball-joints in the control arms also.....A bushing is a piece of formed rubber between two pieces of metal, the bushing also maintains alignment of the suspension as a whole. When the rubber bushing wears through....you have metal upon metal contact (clunk) and lack of precision steering.
