Position the balancer onto the end of the crankshaft.

Assemble the Crankshaft Seal Installer J-41478 threaded rod, nut, washer and the Balancer Installer J-41665. Insert the smaller end of the installer into the front of the balancer.

There is no room to access the balancer/ bolt/. does the rack & pinion or other have to come off? If so I need more detailed info on how to do so.

Removal of the power steering gear & the power steering cooler from the front crossmember will be needed.
