Column Modification
The following step is meant only for cars using the stock steering column. The procedure is
specifically for customers using Unisteer’s Column Bushing #8020490 (pictured below), if you
choose not to use our bushing, a bushing will have to be made.
If you are using an aftermarket column, you must duplicate the length of column
below. This most likely means extending the column. This can either be done
using a straight coupler and a shaft, or if your column is hollow 1-DD, simply slide
a ¾ DD solid into the column for the desired length and pin or bolt it.
This bushing kit is for stock, non-shift steering columns.
Remove the horn ring cap and horn ring by removing the three Phillips head screws that
secure it. You want to note the position of the pieces for reassembly later. The horn ring cap is
retained either by a clutch head style screw, which is removed from the underside of the steering
wheel, or clips. Using a ratchet, extension, and a ¾” socket remove the retaining nut that secures
the steering wheel. Using a steering wheel puller remove the steering wheel. Remove the tension
spring, and seat from the shaft. Disconnect, and remove the neutral safety switch. Disconnect the
horn, and turn signal wiring from underneath the dash. Disconnect the upper column clamp, and
the floor mount. Remove the detent from the lower column tube. The column should now be able
to be removed from the car. Cut the shaft of the steering box as close to the housing as possible.
Disassemble the upper half of the steering column by removing the 3 Phillips head screws from
the lock plate. Remove the turn signal housing carefully. Do not damage the wires. Disassemble
the lower portion of the column by removing the 3 hex screws on the tube. Remove lower bearing
and the inner column shift tube.
Measure from the bottom of the column up 1.75”, and make this cut as straight as
possible. There will be 2 existing holes in the tube that line up with the new column bushing. The
third hole will need to be drilled. Place the column shaft along side the column and calculate the
length needed, so between 1”-1.5” of the shaft will extend out of the bottom of the column.
MEASURE CAREFULLY! Clean and sand the shaft until it fits the new bushing snugly.
Reassemble the column completely. And insert the new bushing last. Fasten the new bushing
with the screws provided.
