Installing the Rear Axle to the Frame
At 17:21 in
Our GMT400 Suburban Frame Off Big Block Build is Rolling! (Junkyard 14 Bolt Prepped By Logan)
What happens here
With the leaf springs and shackles prepped with new polyurethane bushings, the next step is to install the newly painted rear axle onto the chassis. First, carefully roll the entire axle assembly under the rear of the frame. Then, use an electric jack or other lifting mechanism to align the axle with the leaf springs and shackles. Securely bolt the leaf springs and shackles to the frame and the axle, ensuring all connections are tightened to specification. This step brings the rear of the chassis to a 'rolling frame' state.
Goal: Attach the restored rear axle to the truck chassis, creating a rolling frame.
