    Q:
    What should be checked before removing Piston/connecting rod assemblies for the 2007 Chevrolet Avalanche? Posted by Juancarlos M.
    A:
    Before removing piston/connecting rod assemblies, you should check for ridges at the upper limit of ring travel in each cylinder and remove them if present to avoid piston breakage. You should also verify connecting rod endplay with feeler gauges and address any deviations to ensure it falls within the service limit.
