How to replace the front crankshaft seal on GMC Sierra 1500 Classic?

The crankshaft balancer needs removal before changing the crankshaft front oil seal. You must employ a proper seal puller to extract the crankshaft front oil seal after which you should check the engine front cover seal bore area for any damage. A proper lubrication of new seal exterior using clean engine oil requires the use of a Cover Aligner and Seal Installer (J 35468) and a hammer for placement onto the crankshaft front oil seal that needs to be flush and square against the engine front cover. Finally, reinstall the crankshaft balancer.
