How Do You Remove An Astro Van Subframe Assembly?
The Chevrolet Astro van is an interesting vehicle because the front of the vehicle has a traditional body-on-frame design, but the frame stops short just after the rear transmission, leaving the rear suspension to hang on the chassis itself. If you want to remove the front subframe to either get better access to the motor or replace it with another model, it will take some heavy equipment and work, but it can be done. Step 1 Park the Astro van on the hydraulic lift and set the lifting arms of the lift on the body of the Astro, not the frame. Lift the Astro using the lift and unbolt the driveline from the axle using an open-end wrench. Once it’s disconnected, place the drain pan underneath the rear of the transmission and pull the driveline from the transmission to allow it to empty into the drain pan. Step 2 Unbolt the shift linkage from the column shifter to the transmission from underneath the vehicle using a 3/8-inch ratchet and socket and an open-end wrench. Then unplug the wiring
