12. Reinstall the rack sleeves to support the rack, then slip the long rack mounting bolts in from the rear of the engine cradle. This photo was taken just before securing the rack and you can see how the offset rack bushings move the rack up to better line it up with the spindles and to reduce bumpsteer caused by lowering springs.
13. Once the rack is in place and the steering shaft/pinion shaft secured, the rack retaining nuts can be reinstalled to secure the rack to the engine cradle.
14. AGR’s rack-and-pinion kit includes new Teflon sealing rings for the rack’s fluid lines. Follow the instructions to soften the sealing rings and slip them over the threads of the fittings. Be cautious to not overly-stretch the sealing rings.
15. Thread the pressure and return line fittings into the new AGR rack and tighten. The tube portion of the hoses will have some allowable movement for engine vibration/torque so do not try to over tighten the fittings thinking that they are loose.
16. Return the tie-rod ends to the spindle’s steering arms and secure with the original retaining nuts. You’ll need two new cotter pins (not included with the rack) to finish the tie-rod end installation. Slip the cotter pin through tie-rod end stud and bend back over the stud as shown.
17. Moving on to the power steering pump, the pump’s pulley will need to be removed to access the pump’s mounting bolts. You will need a pulley remover tool and a pulley installer tool for the job, which can be borrowed, rented, or purchased as you see fit.
18. With the pulley out of the way, you can easily access and remove the three pump mounting bolts. If you didn’t remove the pressure and return hoses from the pump earlier, you will need to do so now to remove the pump from its mounting bracket.
19. The new AGR flow-matched power steering pump ships complete with new reservoir and fluid cap. It’s a direct replacement for the Fox Mustang pump.
20. Once the AGR pump is secured with the original mounting hardware, the power steering pulley can be returned to service. Start the pulley onto the pump shaft by hand and then seat the pulley using the proper pulley installer tool. There is not a hard stop to pulley mounting; you need to align the pulley with the existing pulleys for quiet belt operation.
21. As noted earlier, our Falken touring tires had ½ to ¾ tread life left, but the steering rack issues ruined our front tires. We opted to stay with Falken for our rubber choice (the PT722s offered a smooth ride and great wear) but decided to step up to a more performance oriented tire more befitting a 5.0L Mustang with a rack-and-pinion offering better road feel. To that end, we ordered a quartet of Falken’s Azenis FK453, its summer performance tire.
22. The Falken Azenis FK453s all mounted, balanced, and ready to carve up the road with our new AGR steering setup. The FK453 features an asymmetrical tread pattern with large shoulder blocks for great handling wet or dry. Its rigid design enhances high speed stability and cornering, something the Fox Mustang could use a little help with. At the time of this writing, we’ve had the FK453s mounted up for about a month. They’ve worn well and make highway on-ramps a lot more fun! MM
