    Q:
    How to replace the front crankshaft seal on Chevrolet Avalanche 2500? Posted by Customer
    A:
    The first step to replace the crankshaft front oil seal requires the removal of the crankshaft balancer while protecting both the engine front cover and crankshaft sealing area from damage. The second step involves the removal of the crankshaft front cover oil seal. A fresh engine oil application must coat the new crankshaft front cover oil seal before its installation process. Installation of the crankshaft balancer needs to follow the use of the Front Cover Oil Seal Installer (J 42851) to put in the oil seal before removing the tool to reinstall the balancer.
