  • Steering sectors
  • Both my ‘46 and ‘47 2Ns have steering “wobble”…. The arms move about 1 inch each way without moving the trailing arms or the steering wheel. What kind of trouble am I in? Is there an easy fix?

  • I suppose that it is impossible for the trailing arms not to move, but what I meant was the front wheels don’t move. The slop is in the arms and linkage

  • Not good news. The gears in the steering are worn out. There is little or no adjustment for wear. To fix this you have to remove the steering gear housing from the transmission. You can leave the top of the transmission in place, but the housing above the split line through the bearings for the steering arms has to come off. This means pulling the hood and disconnecting all the linkages and wiring.

    Get a parts manual and the shop manual. At least a FO4 manual. This will tell you the parts you need and how to do it.

    The parts a somewhat expensive, but are available. The sectors wear near the center of the gear, so they will be loose in the center while tighter at the ends. The pinion wears all over, and is usually the first thing to go. It is tempting to just get the pinion, and reuse the sectors, but 9 times out of 10 you will have sloppy steering near the straight ahead position, and will kick yourself for not doing it right.

    Be sure to replace any bearings that are the slightest bit loose, and all the seals and gaskets.

    It is not a difficult job, just time consuming. You don't want to have to do it over!

  • Nothing to fear. Its a simple repair using new parts. The tricky part is the thrust washers on the sector bearings. They set the backlash on the steering gears and originally came in different thicknesses but are no longer available. The originals will be worn and you may have to make new ones to get the setup back to specification.

  • Thrust washers? Are we talking thin washers. Brass washers Where do I go to get good education?

  • You will see them when you take it apart-fairly thick and can be augmented with shim stock cut to fit.
