This procedure covers the removal and replacement of the upper steering shaft on a 1994-2007 Dodge Ram 2500 4WD with the 5.9L Cummins diesel engine.

Warnings

⚠️Do not start the engine or turn the steering wheel with the steering shaft disconnected, as this can damage the clockspring and disable the airbag system.

⚠Failure to properly align the steering shaft can cause binding, poor steering response, and premature wear.

⚠The steering column contains SRS (airbag) components. Wait at least 2 minutes after disconnecting the battery before working near the steering column.

Preparation

Park vehicle on level ground and apply parking brake
Place wheel chocks behind rear wheels
Disconnect negative battery cable and wait at least 2 minutes before proceeding
Center the steering wheel and front wheels in straight-ahead position
Lock steering wheel in place using ignition key or steering wheel lock
Raise front of vehicle and support securely on jack stands at frame rails

Procedure

1
Access upper steering shaft from cabin
Remove the lower dashboard trim panel or knee bolster below the steering column to access the upper steering shaft. On some models, you may need to remove the lower steering column cover. Note the location of all trim fasteners for reassembly.
2
Mark shaft alignment
Using a white paint marker or scribe, make alignment marks across the upper steering shaft coupling and lower shaft coupling. Mark both the shaft splines and the coupling body. These marks are critical for proper reassembly to prevent steering wheel misalignment.
⚠Accurate alignment marks are essential. Take photos if needed for reference during reassembly.
3
Remove coupling bolt
Locate the coupling bolt that connects the upper and lower steering shafts at the firewall area. Apply penetrating oil if needed. Remove the coupling bolt completely. Note that this is a single pinch bolt with a patch coating.
ℹ️The coupling bolt should be replaced with a new bolt during reassembly as it uses thread-locking patch.
Torque spec
Coupling Bolt34 Nm (25 lb-ft)
4
Separate steering shaft coupling
Carefully spread the coupling clamp using a small pry bar or by tapping the coupling with a plastic mallet. Do not use excessive force. The upper shaft should slide out of the lower shaft coupling once the pinch bolt is removed and the coupling is slightly spread.
5
Remove upper shaft mounting hardware
Working from inside the cabin, locate the mounting bolts that secure the upper steering shaft bearing or support bracket to the steering column or firewall. Remove these mounting bolts and any retaining clips or brackets.
6
Remove upper steering shaft
Carefully slide the upper steering shaft assembly out through the cabin. Guide it past any wiring harnesses or other components. Inspect the removed shaft for wear, damage, or excessive play in the universal joints or bearing.
7
Prepare new upper shaft
Compare the new upper steering shaft to the old one to verify correct part. Clean the splines on the lower shaft coupling using a wire brush. Clean the splines dry and do not apply anti-seize or lubricant to the coupling splines, as this is a safety-critical steering connection that must maintain full clamping friction. Verify the splines are free of debris before assembly.
8
Install upper shaft assembly
Guide the new upper steering shaft into position from inside the cabin. Install the mounting bolts that secure the shaft bearing or support bracket to the steering column or firewall. Torque the mounting bolts to specification.
9
Align and connect shaft coupling
Align the alignment marks made during disassembly. Slide the upper shaft into the lower shaft coupling, ensuring the splines engage fully and the alignment marks line up precisely. Verify the steering wheel is still centered and locked in the straight-ahead position.
⚠Misalignment will cause the steering wheel to be off-center when driving straight. Verify alignment marks match exactly.
10
Install coupling bolt
Install the new coupling bolt through the coupling clamp. Ensure the bolt passes through both the coupling and the shaft groove or flat. Torque the coupling bolt to specification. Verify the coupling is tight and there is no play between the upper and lower shafts.
Torque spec
Coupling Bolt34 Nm (25 lb-ft)
11
Verify shaft operation
Before reinstalling trim panels, carefully unlock the steering wheel and rotate it slowly by hand from stop to stop. Check for smooth operation, no binding, clicking, or excessive play. The shaft should move freely without resistance.
12
Reinstall interior trim
Reinstall the lower steering column covers, knee bolster, and any dashboard trim panels removed during disassembly. Ensure all clips and fasteners are properly seated.

Reassembly

Lower vehicle from jack stands
Reconnect negative battery cable
Start engine and verify no warning lights related to steering or airbag system
Test drive vehicle at low speed in a safe area to verify steering wheel is centered when driving straight
