Engine mounts are usually trouble free, but if there are broken or worn out ones, they should be replaced to avoid damaging the drive line. To inspect the mounts, support the vehicle on jack stands and place a jack under the engine
Oil Pan on top what is a block of wood. Lever it a little just enough to take some of the weight off the mounts, then check for cracks, turning to metal and separation of the rubber from the bushing. Insert a large screwdriver or pry bar between the mount and the engine or frame; look for any relative movement; if movement is noted, reduce the weight of the mount fasteners. Whenever the mount is removed, the negative cable of the battery has to be detached and depending on which mount is being removed some other parts like the air filter housing, battery tray etc. Lift the vehicle on jack stands once more, and then insert a piece of wood firmly between the head of the jack and the oil pan to take load off the engine/trans axle if the vehicle is to be left elevated for some time. Precautionary measures, especially should not more than one mount be disconnected at a given time unless the engine is to be removed. To achieve this perform the power train mounts, to balance the engine trans axle assembly make sure that the assembling has balanced weight and then tighten the mounting bolts. Apply floor jacks to support both the engine and trans axle then unbolt the required studs and nuts related to the mounts and their brackets then further space the separates by as much as a quarter inch. Position the front and rear trans axle mounts in their brackets, after that, fasten five bolts up to the specified torque. Last lift the floor jacks, place the vehicle using jack stands, move the engine and trans axle up and down, tighten the rear through-bolt, retract the under-vehicle splash shield and finally brought down the vehicle.
