Rear Mount

First, raise and support the vehicle where the transmission mount for a 2WD vehicle are to be changed. With the help of a transmission jack, support the transmission, take off the 2 nuts fasten the transmission mount to the transmission support. Before disconnecting, lift the transmission off the support and remove the four transmission mount bolts including transmission mount and transmission mount spacer bolts. Second, remove the transmission mount spacer. Step one for installation, and install the transmission mount spacer followed by the spacer bolts. Subsequently, install the transmission mount and remember to tighten up the four bolts to 55 N.m (41 lb ft). Lower the transmission and secure it with the installation of the 2 nuts on the transmission mount to tighten them on 57 N.m (42 lb. ft.). Finally, slide out the transmission jack and drop the vehicle.

A proper vehicle lifting system should be used first to replace the left Engine Mount. First remove the wheel assembly then take off the engine shield when it exists. For the replacement of the lower intermediate Steering Shaft the technician should first support the engine using a jack stand and wood block before disconnecting the Steering Shaft. Initiate replacement of a mount by detaching its through bolt which fastens the mount-to-frame bracket and next loosen the through bolt that secures the right side. Raise the engine using the jack stand to enable one-sided tilting once you remove the heater pipe bracket bolt from the Engine Mount. You should detach the Engine Mount bolts followed by the Engine Mount which you may need to manipulate during the removal process. Place the new Engine Mount into position and articulate it when needed before starting to install the Engine Mount bolts while using the first bolt to achieve alignment. Lower the engine while securing both bracket bolts to 85 nm (63 ft. Lbs.). Install the Engine Mount-to-frame bracket through bolt and tighten it to 50 nm (37 ft. Lbs.). After removing the jack stand and reinstalling the lower intermediate Steering Shaft proceed with reattaching the engine coolant pipe bracket bolt from the Engine Mount. End the procedure by reinstalling engine shield followed by wheel and tire assembly then lowering the vehicle.

The first step to replace a 2WD transmission mount requires a vehicle that is elevated for support. A transmission jack will support the transmission while you detach the 2 nuts which maintain the transmission mount to the transmission support. Lift the transmission off its support position while unbolting the transmission mount from the support before proceeding with transmission mount removal. You must erase the spacer bolts which secure the transmission mount spacer then discard the transmission mount spacer . Start your installation process by adding the transmission mount spacer to the setup followed by securing spacer bolts . Install the transmission mount before applying fastening techniques to bolt the rear section to 55 Nm (41 lb ft). Use the 2 nuts to secure the transmission while you lower it. Tighten these nuts to 57 Nm (42 lb ft). The vehicle requires a transmission jack removal before lowering it.

Replacing the right engine mount starts with raising and supporting the vehicle before removing the wheel and tire assembly and engine shield when present. First support the engine with both a jack stand and wood block before removing the through bolt from the mount-to-frame bracket on the replacement side while loosening the left side through bolt. Usage of the jack stand to raise the engine allows tilting before removing the engine mount bolts for complete engine mount removal when necessary. Begin engine mount bolt installation by first putting in bolt position to enhance mounting efficiency. The process requires setting engine mount bolts at 50 Nm (37 ft. lbs.) then lowering the engine to install the engine mount-to-frame bracket through bolt which needs tightening at 85 Nm (63 ft. lbs.). Last, take off the jack stand while reinstalling any equipped engine shield then reinstall the wheel and tire followed by lowering the vehicle.

Firstly, lift and support the vehicle and then support the transmission using a transmission jack in place of the transmission mount which is for RPO Z71. Loosen the two nuts holding the transmission mount to the transmission support, lift the transmission off the support and remove the mount to transmission bolts and also the mount spacer. For installation, you first install the mount spacer and then connect the transmission mount with the vehicle. Make sure to carefully adhere to the Fastener Notice in Service Precautions, then mount the transmission bolts and tighten to 60 Nm (44 ft. lbs.). Lower the transmission and secure it by installing the two nuts to the transmission support and tighten them to 57 Nm (42 ft. lbs. - N). Finally, take the transmission jack after lowering the vehicle.
