Do I need to provide additional support when changing the front subframe?
I am replacing the front subframe. I would like to know if the upper engine mounts are strong enough to hold the engine in place while chaning the subframe.
No, you need to support the engine with a cherry picker or hoist. You don't have to pull the engine just pick it up and get the weight off the subframe.
Good Lord NO!! The engine and and transmission assembly MUST BE supported from the top!! If not, they'll literally fall out of the car causing serious injury or death!! HTH -Jim
Actually the engine and transmission are not mounted to the sub frame on that car. The only part that connects to the frame is a small link on the back side of the engine that keeps it from moving forward or back. You can remove the sub frame without any additional support.
This is for the 2.5L only. The 3.5L must be supported.
