For accurate findings a road test should be carried out in the load condition complained of(unladen/laden/partially laden) with the driver and the test sheet should be filled in.
Please set the completely filled-in test sheet on fault analysis for vibrations and noise in the vehicle and the corresponding data sheet for flange/inclination angle measurement in Xentry TIPS as a case module.
Markets without TIPS fax the test sheets to the responsible contact in the MPC.
