You will then need to use your hydraulic jack to support the lower sub frame assembly as you will need to lower it 4-6 inches to gain access. It is bolted on by four monster stretch bolts that must be replaced
when you reinstall the sub frame.The front two go up thru the pillow block mounts on the frame.
These are 21mm hex bolts and they are 70ft-lbs you will need a serious breaker bar to get them loose.
