Complaint There may be creaking noises when steering while stationary or driving slowly. See Example Noise attachment Cause The vehicle level of the front axle may be too low. The noises when steering can be caused by continuous contact of the end stop buffer with the damper tube. Remedy IMPORTANT: Do not apply document to vehicles outside of the listed validity range. The vehicle level must first be measured using the romess inclinometer (follow WIS instructions!) and the measured values should be compared with the target values in the Wheel Alignment online tool. If the vehicle level is out of tolerance, then the springs on the front axle must be replaced in order to correct the level. The currently installed springs can be pulled up in the XENTRY Parts Information tool through the corresponding selection. How to identify currently installed springs: • Check for colored dots on the front springs. • If no dots or color markings, please check if there is a parts label that is affixed to the spring. If the MB part number is listed, continue with process listed in the paragraph below. • If the part label does not contain an MB part number, is missing or illegible, please check for a barcode label with a 3 digit number. See "Spring Barcode" picture for example.

The spring listed in the parts catalog will have a "color marking" indicator. If the dots on the spring and the color listed in the parts catalog is the same then you have the part number of the currently installed spring. If it does not, then you need to clear the vehicle specific filter by using the funnel icon on the right side column of the page and clicking "no filter" at the top and then "apply filter" (see "Clear Vehicle EPC Filter" for how-to pictures). Proceed to finding the spring that matches the color dots on the vehicles currently installed spring. • In order to find the correct or next highest spring, the spring filter must be removed in the XENTRY Parts Information tool. • The spring item numbers are normally listed in s
