Not the usual item to start a restoration on, our '71 Challenger R/T yielded this battle-weary steering column. Getting it in shape made for a relaxing weekend project. Mopar columns are relatively simple to work on as compared to the complex units of today, and the floor-shift examples found in most factory musclecars are the simplest.
There's a fine line that separates the look of a fully rebuilt Mopar from a car that is just fixed up. Be it a purist's authentic resto or a tastefully and functionally modified car, you can always spot the machine that received the whole nine yards. Everywhere you look, it's quality, clean, and like new or better. To perform the total rebuild, you must go into each component and work the details before moving to the next. You'll find yourself working on components of the car that most guys take for granted. How many late-model Camaro or 5.0 Mustang guys will blueprint the pedals, rework the window mechanism, or, as we do this month, fully rebuild a steering column? Not many, we guess.
The details truly make the difference. Take the oft-neglected steering column. Slip behind the wheel of a nice looking Mopar, and the little things can detract and annoy. These cars are 30-plus years old and show it: The steering wheel begins to growl when turned, the signals won't self-cancel or work at all, and the ignition key has to be wiggled to get the engine to fire. Suddenly, that pretty Mopar acts like a tired old car. By the same token, if the wheel turns as smooth as silk, the controls snap positively like they were made yesterday, and the finish quality looks better than it did leaving Hamtramck, the sense of quality prevails. We had all types of woes brewing in the column of our '71 Challenger R/T: faulty electronics, a junkyard-quality finish, and dried, dirt-encrusted bearings made it anything but a smooth operator. A full cosmetic and functional rebuild set us back a couple of days, but it put us way ahead of the game when it came to a quality resto effort.
The first item to come off...
The first item to come off was the steering wheel. Most columns have steering wheels which spline directly to the shaft; however, in E-Body examples such as this-Tuff Wheel and Rim-Blo cars included-the wheel bolts to an adapter. Remove the wheel's outer trim, typically retained with screws from the backside, and then separate the horn mechanism.
You'll need a steering-wheel...
You'll need a steering-wheel puller to separate the adapter hub (or steering wheel) from the splined shaft. Underneath is the upper bearing casting, which houses the signal switch and shaft bearing.
With the wheel and adapter...
With the wheel and adapter hub removed, you can now get to the turn-signal mechanism. Next, remove the column mounting bracket and wiring trough. Inspect the signal mechanism for broken plastic canceling tabs. Electrical checks should be made to ensure the switch is working (see sidebar). Unbolt the turn-signal arm first and then the three small retaining screws from the plastic mechanism. The switch wiring probably won't come out of the column at this point, but there will be enough slack to pull the switch up and swing it out of the way.
To make working on the column...
To make working on the column easier, we made this simple bracket, which bolts in place of the factory mount and allows the column to be bolted into a vice.
Three screws hold the upper...
Three screws hold the upper bearing housing to the lock housing. Remove the screws and separate the two housings to reveal the shaft-lock mechanism and ignition-switch gear. A pin through the steering shaft (covered by a thin sheetmetal sleeve) retaining the lock plate must be removed. Chrysler recommends a special pressing tool to remove the pin. With the column out of the car, a drift is fine as long as the shaft is well supported from behind, as shown.
With the lock plate off, the...
With the lock plate off, the steering shaft can be pulled out from the bottom of the column. Two screws and a guideplate retain the lock lever mechanism. Remove the guideplate. Next, remove the ignition lock. With the ignition in the lock position and the key out, depress the spring-loaded lock retainer with a stiff wire or small screwdriver through the access hole, as shown, and pull the lock out.
