    Q:
    How to replace rear Crankshaft Seal on V8 engine on GMC Yukon? Posted by Triston A.
    A:
    Remove the transmission and the driveplate. Take a screwdriver and pry the Crankshaft Seal from the rear cover without nicking or scratching the seal bore, or crankshaft. Note how far it is recessed into this housing bore prior to removal so that the new seal can be set at this depth. Grab a shop towel and thoroughly clean out all traces of oil and dirt from the block's seal bore. Do not lubricate the seal or touch the sealing lip. Make sure that it is installed properly as it has reverse-lip design on it. The second requirement is that you must see its part number when this seal has been installed. The best way to do this is to use a tool for installing seals to fit in this new one by pushing the tool onto it until it goes back into its place completely. In case, there isn't an appropriate seal installing instrument, one can take a big drift and softly drive this new seal directly into its bore located near rear cover; after which, flush them together so they appear even with one another. Finally, install drive plate and transmission again.
