Thank you for purchasing an ididit steering column!
These instructions will give you an
overview of mounting the steering column
in the most common street rod or hot
rod applications. The steering column
must be supported at the dash with a
dash mount and supported where it
protrudes through the firewall with
a floor mount. (Figure 1) It is vital that
Figure 1
the steering column is tight and secure.
Attaching your column to a steering gearbox or rack & pinion system may
require some combination of u-joints, couplers and shafts.
It is highly recommended that you test fit your steering column before
painting the column. Test fitting now will save you a headache later
on. We are not responsible for paint.
For proper installation of u-joints and couplers on your column, follow
manufacturers recommendations, but in general, there are two basic styles
used on your ididit steering column:
DD Output Shaft (our most common shaft):
Double “D” output shafts are either 1” or 3/4” diameter.
Most u-joint manufacturers use two setscrews to fasten the
u-joint to a DD shaft. These two set screws are positioned 90
degrees from each other. To install a u-joint over the shaft
simply slide the u-joint over shaft until it is fully engaged
in the joint (Borgeson Universal recommends 7/8”–1” engagement). Use
a marker to make a mark through each hole in the joint. Remove the joint.
Using a quarter inch drill bit, spot the shaft where the setscrews will seat.
Re-install the joint and install setscrews and jam nuts. (Note: all joint mfg’s
recommend using a thread-locking compound on the setscrew and nut).
Spline Output Shaft:
Spline output shafts are either 1”-48 or 3/4”-36. To install
your u-joint simply slide the u-joint over the spline, taking
care to line one set screw up with the flat spot on the shaft.
If the shaft has no flat spot, slide the joint on so the shaft is
fully engaged in the joint (Borgeson Universal recommends
7/8”–1” engagement). Use a marker to make a mark through hole in the
joint. Remove the joint. Using a 5/16 inch drill bit, spot the shaft where
the setscrew will seat. Re-install the joint and install setscrew and jam
nut. (Note: all joint manufacturers recommend using a thread-locking
compound on setscrew and nut).
Tilt Lever:
After removing all items from the package, screw
the knobs onto the levers. The tilt lever is installed
on the left side of the column in the threaded hole
closest to the dash. We recommend using Locktite.
Turn Signal Lever:
The turn signal lever is inserted into the hole
closest to the top of the column. With the steering
wheel and adaptor removed, look down from the
top of the column and you’ll see two holes on
the turn signal switch. One is D shaped and the
other is round. With the lever in place, insert the
provided screw into the round hole. Use a #2
Phillips screw driver to tighten the screw tightly.
Emergency Flasher Knob:
The emergency flasher is threaded into the hole
located on the right side of the column. You will
notice the nylon switch that the flasher screws into
is flush with the outer surface when in the OFF
position. It is easy to accidently turn the flashers
ON while installing, which could lead to problems
later. Check to make sure that the knob is in the OFF
(out), position before continuing.
If Column Shift Application:
Place column shift knob onto the shift lever. Once
the lever is in place, use setscrew (provided) and
adjust knob so set screw is pointing away from you,
tighten setscrew. Do not remove the upper shift lever
for any reason! The tension spring will pop out and
it is very difficult to re-install.
Wiring your Column
This ididit steering column uses a standard 3 7/8-inch male connect.
However, some GM columns use a 4 ¼-inch male connector. Connectors
do not interchange and must be used in pairs. A mate to the 3 7/8 inch plug
is available through ididit. If you need to change this connector for any
reason the following schematic will be helpful.
Horn Button Wiring:
A horn may require two wires to properly function with an ididit column.
The center lug on the button should connect to a
horn wire, which is provided by ididit with your
steering column. This horn wire will slide into the
horn cam (white plastic tube sticking up on the
top of the column). If there is a second wire off to
the side it is probably a ground wire (check with
the horn button manufacturer to be sure). This
is normally used when an o-ring is used to hold
the button in place. The o-ring does not provide
sufficient ground, therefore, an additional wire
is provided to ground the horn button. If there is not a hole in adaptor to
ground to, use one of the puller holes with a short bolt to attach the wire to
the adaptor.
Synchronizing your Column
In order to insure proper functioning, this steering column must be installed
in sync with the rest of the steering system. Turn signal cancellation and
wheel position, as well as smooth steering operation depends on it. Although
not all of them may need adjustment, the complete table of steps required
for full synchronization is as follows:
1. The front wheels must be pointing straight forward with the steering
toe set reasonably close.
2. Rotate the input shaft of the gearbox or rack from lock to lock and set
the box exactly half way between. For example, if the shaft rotates
three full turns from lock to lock. The center will be at 1½ turns from
either locked position.
3. Install the steering arm and drag link, and adjust tie rod ends to get the
drag link to fit without moving either the box/rack or the front wheels.
Rotating each tie rod end the same number of turns will preserve
4. With the column mounted in position and two joints are used on a
shaft, the forks of the yokes
closest to each other should be
in line, or “in phase”. Premature
wear or binding can result if the
u-joints are not phased properly.
Sometimes if the u-joints are at
a severe angle, even if they are
phased correctly, a hard spot in the steering may occur for no apparent
reason. If this happens, index the u-joints two or three splines in one
direction. The hard spot should disappear or be minimized.
5. Install the shaft or joint on the gear box/rack. Leave the upper part of
the shaft unconnected for the time being.
6. Position the column
housing so that the signal
switch arm is level to the
left hand side.
7. Install
through firewall, into
your joint.
8. To
synchronizing of your
column the finished
installation of your
column should look like
Diagram 1
diagram 1 (on the previous page). If the post on horn cam is not at
10:30, grasp post and turn it until it is at 10:30. Once completed, your
column will be in sync.
Steering Wheels:
The top shaft of the column is the same as a
GM passenger car from 1969-94 (Van columns
& some truck columns are not the same as
passenger cars). Original wheels from these
years will bolt directly to the top of the column
with no modifications. An aftermarket wheel
will require an adaptor. Align the spline and horn
cam on the top of the column with those in the
adaptor and slide it onto the column. A nut has been provided with your
steering column. The nut will secure the wheel to the top of the column.
The nut on the wheel should be torqued to 35 ft lbs.
Column Shift Linkage Installation:
At the bottom of your column you will notice a
lever. This is the shift lever where your linkage
will attach from the column to the transmission.
Note the 5/16 hole through the bushings, most
kits use a 5/16 bolt to secure the rod to the
column. Please follow the kit instructions for
the linkage, but make sure that no part of their
kit hits the metal portion of the lever, as it will
create a rattle in the column.
