INSPECT Checking     
DANGER Risk of death caused by vehicle slipping or toppling off of the lifting platform. Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer. AS00.00-Z-0010-01A
DANGER Risk of injury  caused by moving parts that can pinch, crush  or, in extreme cases, even sever  extremities No parts of the body or limbs should be within the operating range of the mechanism when moving components. AS00.00-Z-0009-01A
NOTES Notes on tire flat spots   AH40.10-P-1030-01A
IMPORTANT The tire balance becomes poor with increasing tire wear. This means that the tire does not wear completely symmetrically through its rotation pattern. The level of wear differs in different areas (on front axle outside shoulder or center tread wear on rear axle)  
IMPORTANT It is essential to pay the utmost attention to cleanliness.
Dirt and rust on the wheel, hub, brake drum or centering or clamping device may impair the balancing result
   
1 Hoist vehicle with lifting platform until wheels are free    
2 Check play of front axle ball joints IMPORTANT If necessary replace the respective part.  
3 Check tires and rims for wear, damage and flat spots IMPORTANT If a rim is damaged, it must be replaced. If the tire is at the wear limit or damaged, it must be replaced.
Tires must always be replaced in pairs by axle.
 
4 Check tire inflation pressure of all wheels and correct if necessary IMPORTANT See tire inflation pressure table in the fuel filler flap.  
5 Conduct a road test IMPORTANT Drive vehicle for at least 20 km at a speed of >100 km/h to ensure that the flat spots are driven out of the tires.
Only then can the vehicle be evaluated!
 
6 Hoist vehicle with lifting platform until wheels are free IMPORTANT After the test drive, it is necessary to immediately  take the load off the wheels to avoid formation of flat spots.  
7 Mark position of wheels IMPORTANT Mark position of wheel relative to wheel hub.  
8 Remove all wheels    
9 Clean all wheels    
10 Check wheel balancing machine IMPORTANT Ensure that the wheel balancing machine meets the quality, display accuracy and turnover test requirements.  
11 Check lateral and radial runout at all wheels   AR40.10-P-1025A 
Radial runout *BE40.10-P-1002-01A 
Lateral runout *BE40.10-P-1004-01A 
12 Balance wheels on wheel balancer and perform smooth running optimization Only perform if impermissible lateral or radial runout was found in operation step 11.
IMPORTANT The wheels with the best radial/lateral run out values are to be mounted onto the front axle.
AR40.10-P-3201-01A 
13 Mount all wheels When mounting the wheels, ensure that they are precisely centered and correspond to the position markings. Start off by turning in the wheel bolts to the mounting face in a cross pattern and then tighten them to the specified torque value.
IMPORTANT 1/10 mm centering difference = 20 g imbalance.
 
14 Perform test drive and evaluate vibrations/smooth running of vehicle IMPORTANT Drive the vehicle for at least 20 km at a speed of >100 km/h.
