Installing Longitudinal Member For Wheel Housing

Information

• Before final assembly, make sure you fully understand all the work steps involved and carry out a trial assembly without applying adhesive.
• The bonding process can only be carried out reliably when a smooth and swift sequence of operations is guaranteed.
• Do not begin bonding work until all materials and tools necessary for later repair work are available.
