Two tooth steering bad rebuild

[Patrick L.]

Before trying anything rash, I'd recommend adjusting the box properly. To do that you'll need the Ford Service Bulletins. There are 4 adjustments that need to be done in order.

If the steering sector teeth have grooves (divots) in their faces, plan on replacing the worm gear, too. Although you won't see wear on the worm gear like you will on the sector teeth, you can bet it's worn. Replacing only the sector will not reduce play to acceptable limits because you'll be trying to adjust a new piece against a worn one. I'm convinced that's why we read about so many dissatisfied owners after they have "rebuilt" their Model A steering boxes = still too much play at the steering wheel. Ask them if they replaced the worm gear during the rebuild and usually the answer is "no". Bite the bullet during this rebuild and either install a new worm gear yourself or have a machine shop remove and replace it for you. NOT a fun job or one generally done with hand tools alone. But if you only replace the sector, it's likely that you'll need to go back in and replace the worm gear, too. By then the teeth on the new gear will have worn against the rough old worm gear. And be sure to replace the two sector bushings and ream/hone them to snugly fit the new sector. Otherwise, there will be upwards and downwards movement of the arm through the frame rail, besides creating a pathway for the lube to leak out. The sector should turn by hand with some resistance.
For the millionth time mentioned on this website, do not put in chassis grease as a lubricant. You must use a steering gear lube (such as Penrite) or 600w from the vendors, although the latter will leak eventually.
