Installation Instructions for ‘79-‘91 Chevy & GMC Truck 2 joint Steering Shaft
Part # 000935
CAUTION: NOT ALL VEHICLES CONFORM TO PUBLISHED SPECIFICATIONS! TEST FIT THIS
ASSEMBLY IN YOUR TRUCK BEFORE PAINTING OR ALTERING IN ANY WAY. ONLY
ASSEMBLIES IN NEW CONDITION WILL BE ACCEPTED FOR RETURN OR EXCHANGE.
REMOVAL:
1. Engage the steering column / ignition switch lock with the steering wheel and wheels centered. (NOTE It may be
necessary to remove the upper & lower bolts prior to locking ignition for accessibility)
2. Remove the stock steering assembly by removing the bolts that attach it to the steering box and steering column
shafts. These connections are often rusty and penetrating oil or a few taps with a hammer may be needed to separate
the joints from the shafts.
INSTALLATION:
3. Fully collapse the Borgeson shaft assembly. Install the Double D column end in the universal joint to the depth
shown in Figure B. The universal joint will be secured with two set screws as shown in Figure C. Tighten the short
set screw against the shaft. The longer of the set screws must pass through one wall of the tube only. If the long set
screw does not line up with an existing hole in the tube, a 3/8” diameter hole must be drilled through one wall of the
tube only. Mark the shaft and remove the universal joint; do not drill through the universal joint. The set screw
should pass through this hole and bear against the opposite wall of the tube. Reinstall the universal joint and tighten
both set screws and then tighten lock nuts.
4. Slide the splined universal joint over the steering box input shaft by extending the telescoping shaft. A seat must be
provided for the set screw as shown in Figure A. (NOTE The existing factory flat spot will not be used) Tighten the
set screw to mark the shaft and then remove the universal joint from the shaft to file a new flat spot on the splined
shaft. Install the universal joint and tighten the set screw into the seat and then tighten the lock nut.
5. After approximately 100 miles, retighten all setscrews and then lock nuts. If you wish to use a product such as
Loctite, we recommend Loctite 222 for ease of removal.
