    Q:
    What steps should be followed to replace the Engine Mounts for the 2007 GMC Sierra? Posted by Katerina B.
    A:
    Disconnect the cable from the negative terminal of the battery, raise the vehicle and support it securely on jackstands. On 4WD models, remove the interfering driveaxle. If working on the left mount, it may be necessary to remove the left inner fender splash shield and the exhaust manifold heat shield on most models. Remove the engine mount-to-frame bracket bolts. Attach an engine hoist to the top of the engine for lifting. Do not use a jack under the oil pan to support the entire weight of the engine or the oil pump pick-up could be damaged. If a hoist is not available, a jack can be placed under the large casting lugs on each side of the engine block at the rear to support the weight of the engine while the engine mounts are being replaced. Unbolt the mount from the engine block, then raise the engine far enough to remove the mount from between the engine and the frame. Installation is the reverse of removal. Use non-hardening thread locking compound on the mount bolts and be sure to tighten them to the correct torque specifications.

    Q:
    How can you determine if the Motor And Transmission Mount needs to be replaced for the 2007 GMC Sierra? Posted by Nikole G.
    A:
    Insert a large screwdriver or prybar into the space between the transmission extension housing and the crossmember and try to pry the transmission up slightly. If the transmission moves significantly, the mount needs to be replaced. You can Select Your Vehicle to see complete installation and repair tips.
