With the axle mount installed, the Panhard bar's large chassis mount is next. Begin by holding the chassis mount against the rear subframe rails. The axle will need to be lowered to position the chassis mount. It's important that the chassis mount be pushed upward so the U-brackets are in full contact with the bottom of the framerails. If it's not, the mount won't be positioned correctly, which can cause clearance problems with the exhaust system.
