Replace worn front sway bar bushings to eliminate clunking noises and restore proper suspension operation on a 2007 Ram 3500 with Cummins diesel engine.

Warnings

⚠️Never work under a vehicle supported only by a jack. Always use jack stands rated for the vehicle weight.

⚠Apply penetrating oil to rusty fasteners 24 hours before starting work if possible, as corrosion is common on undercarriage components in this model year.

ℹ️The front sway bar on 4WD models is positioned above the front differential and may require maneuvering around axle components.

Preparation

Park vehicle on level surface and engage parking brake
Chock rear wheels securely
Spray penetrating oil on sway bar bushing bracket bolts if they appear corroded
Raise front of vehicle with floor jack at frame rail
Support vehicle with jack stands under frame rails on both sides
Remove front wheels for better access (optional but recommended)

Procedure

1
Locate sway bar and bushings
Position yourself under the front of the vehicle. The front sway bar runs laterally across the frame, forward of the front axle. Identify the two bushing brackets that secure the sway bar to the frame rails. Each bracket is held by two bolts.
2
Support sway bar
Have a helper support the sway bar or use a bungee cord to prevent it from dropping when the bushings are removed. The bar is heavy and may shift position when freed from the bushings.
3
Remove driver side bushing bracket
Using the appropriate socket (commonly 15mm or 18mm — verify actual size on your vehicle), remove the two bolts securing the driver side bushing bracket to the frame. Keep track of any washers or spacers. Lower the bracket and remove the old bushing from the sway bar.
4
Remove passenger side bushing bracket
Repeat the removal process for the passenger side bushing bracket. Remove both bolts and lower the bracket. Extract the old bushing from around the sway bar. The bar should now be free to move.
5
Clean sway bar mounting areas
Use a wire brush to clean the sway bar surface where the bushings contact. Remove all rust, dirt, and old rubber residue. Also clean the mounting surfaces on the frame and inspect the brackets for cracks or damage.
6
Inspect brackets and hardware
Examine the bushing brackets for bending, cracks, or severe corrosion. Check all bolt threads. Replace brackets or bolts if damaged. Verify that the frame mounting holes are not elongated or stripped.
7
Install new bushings
Split each new bushing and position it around the sway bar in the correct location. Most bushings have a split design that wraps around the bar. Ensure the bushing is centered on the bar where it will contact the bracket. Apply a light coating of silicone spray to the inside of the bushing if specified by the manufacturer (do not use petroleum-based lubricants).
8
Install driver side bracket
Position the driver side bracket over the bushing and align with the frame mounting holes. Start both bolts by hand to ensure proper thread engagement. Do not fully tighten yet.
9
Install passenger side bracket
Position the passenger side bracket over the bushing and align with frame mounting holes. Start both bolts by hand. Verify the sway bar is centered and the bushings are properly seated before proceeding.
10
Torque bracket bolts
Torque all four bushing bracket bolts in a cross pattern. No torque value is confirmed in the database. Consult the factory service manual for the exact sway bar bushing bracket bolt torque specification (typically in the range of 65-70 ft-lbs for this application) before tightening. Ensure brackets are flush against the frame. Ensure brackets are flush against the frame.

Reassembly

Reinstall front wheels if removed and torque lug nuts to proper specification
Remove jack stands and lower vehicle to the ground
Bounce the front end several times to settle the suspension and allow bushings to seat properly

Verification

Start vehicle and turn steering wheel full left and full right while stationary to check for binding or unusual noises
Test drive vehicle over bumps at low speed and listen for clunking noises that would indicate loose or improperly installed bushings
Perform visual inspection under vehicle to confirm brackets are secure and bushings have not shifted
Re-torque bracket bolts after 50-100 miles of driving to account for bushing settling
