This procedure covers the removal and replacement of the front sway bar (stabilizer bar) on a 2007 Ram 3500 4WD with the 5.9L Cummins diesel engine.
Warnings
⚠️Ensure vehicle is properly supported on jack stands before working underneath. Never rely solely on a floor jack.
⚠Sway bar is under tension when vehicle is loaded. Components may shift when disconnected.
ℹ️Apply penetrating oil to all fasteners at least 15 minutes before removal to ease disassembly on older vehicles.

Preparation
- Park vehicle on level surface and engage parking brake
- Chock rear wheels securely
- Raise front of vehicle with floor jack at frame rail
- Support vehicle securely on jack stands placed at frame rails behind front axle
- Remove both front wheels for better access
- Apply penetrating oil to sway bar link nuts and frame bracket bolts if corrosion is present
Procedure
- 1Disconnect passenger side sway bar end linkLocate the sway bar end link connecting the sway bar to the passenger side axle. Hold the stud with a wrench while removing the upper nut connecting the link to the sway bar (verify socket sizes against the factory service manual for this application). Remove the link from the sway bar. If link is being reused, leave lower connection attached to axle.
- 2Disconnect driver side sway bar end linkRepeat the same process on the driver side. Use a 15mm socket to hold the stud while using an 18mm socket to remove the upper nut. Disconnect the end link from the sway bar.
- 3Remove passenger side sway bar bushing bracketLocate the sway bar bushing bracket bolted to the frame rail on the passenger side. Remove the two bolts securing the bracket to the frame (verify socket size against the factory service manual). Remove the bracket and note the orientation of the bushing split for reassembly.
- 4Remove driver side sway bar bushing bracketUse a 21mm socket to remove the two bolts securing the driver side bushing bracket to the frame rail. Remove the bracket and bushing. Keep brackets separate if they are marked left and right.
- 5Remove sway bar from vehicleWith both end links and bushing brackets disconnected, carefully maneuver the sway bar out from underneath the vehicle. The bar will need to be rotated and angled to clear the axle, frame components, and brake lines. Work slowly to avoid damaging surrounding components.
- 6Inspect and prepare componentsInspect the removed sway bar for cracks, damage, or excessive wear. Check end links for worn bushings or bent studs. If replacing bushings only, remove old bushings from the bar and clean the mounting surface with a wire brush. Inspect frame mounting points and clean threads on bracket bolts.
- 7Install new or existing sway barIf installing new bushings, slide them onto the sway bar with the split facing toward the rear of the vehicle. Position the sway bar up into place, ensuring it is centered and the end link mounting points are properly aligned with the axle connection points.
- 8Install sway bar bushing bracketsPosition the bushing brackets over the bushings with the split in the bushing facing rearward. Start both bolts on each bracket by hand before tightening. Torque the bracket bolts to specification. Since no verified torque spec is provided, tighten to the factory service manual specification (approximately 65 ft-lbs for this application — confirm in the FSM before final torque).
- 9Connect sway bar end linksAttach the end links to the sway bar on both sides. Install new end links if the old ones show wear. Insert the stud through the mounting hole and install the washer and nut. Hold the stud while tightening the nut (verify socket sizes against the factory service manual). Torque to the factory service manual specification for this application rather than an estimated value.
- 10Reinstall wheels and lower vehicleReinstall both front wheels and hand-tighten lug nuts in a star pattern. Lower vehicle from jack stands carefully. Once vehicle weight is on the ground, torque lug nuts in a star pattern to the factory specification (approximately 145 ft-lbs for this application — confirm in the FSM).
Reassembly
- Ensure all fasteners are tightened to specification with vehicle at ride height
- Verify sway bar bushings are properly seated and bracket bolts are secure
- Check that end links move freely without binding
- Confirm no brake lines or wiring are in contact with the sway bar
Verification
- Perform a visual inspection under the vehicle to ensure all components are properly installed and secured
- Test drive vehicle at low speed and perform gentle turns to verify sway bar operation
- Listen for any clunking or rattling noises that would indicate loose connections
- Check for even handling response when turning left and right
- Re-inspect all fasteners after 50-100 miles of driving
