This procedure covers the removal and replacement of the rear sway bar end links on a 2007 Ram 3500 with 5.9L Cummins diesel engine.

Warnings

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

⚠Sway bar components are under tension. Control the sway bar when disconnecting links to prevent sudden movement.

ℹ️Replace sway bar links in pairs to maintain balanced handling characteristics.

Preparation

Park vehicle on level, solid surface and engage parking brake
Chock the front wheels to prevent vehicle movement
Allow suspension to settle with vehicle weight on wheels before beginning work

Procedure

1
Raise and support vehicle
Position floor jack under rear axle housing. Raise vehicle slightly until rear wheels are just off the ground. Place jack stands under the frame rails on both sides, then lower vehicle onto stands. Keep jack in position under axle for support but not bearing full weight.
2
Locate sway bar links
Identify the rear sway bar links connecting the sway bar to the axle/frame mounting brackets, typically located near each rear wheel. Inspect the actual link design (which may be a bolt-through bushing style or ball-stud style) before proceeding. Inspect for damage, worn bushings, or torn boots.
3
Apply penetrating oil
Spray penetrating oil on both upper and lower mounting nuts of each sway bar link. Allow to soak for 5-10 minutes to ease removal, especially if vehicle is exposed to road salt or has high mileage. Clean threads with wire brush if heavily corroded.
4
Remove driver side sway bar link
Determine the actual fastener size on your link (commonly 18mm or 21mm on this application). Hold the ball stud or bolt while removing the upper nut connecting the link to the sway bar, then remove the lower nut connecting the link to the mounting bracket using the same method. The link may need to be pried or pulled free from the mounting points. Remove the link assembly.
5
Remove passenger side sway bar link
Repeat the removal process for the passenger side sway bar link. Hold the ball stud with wrench while removing both upper and lower mounting nuts. Remove link assembly and set aside.
6
Inspect mounting points
Examine the sway bar and axle mounting brackets for wear, cracks, or damage. Check sway bar bushings for deterioration. Clean mounting surfaces with wire brush to ensure proper seating of new links.
7
Install new driver side link
Position the new sway bar link between the sway bar and axle bracket. Start the upper nut onto the ball stud connecting to the sway bar, threading by hand. Then start the lower nut onto the ball stud at the axle bracket. Do not fully tighten yet.
8
Install new passenger side link
Install the passenger side sway bar link in the same manner. Thread both upper and lower nuts by hand first to ensure proper alignment. Links should move freely on ball studs without binding.
9
Tighten sway bar link nuts
With vehicle weight still on jack stands, hold each ball stud with an 18mm wrench and tighten the nuts with a torque wrench. Since torque specifications are not available in the database, tighten to the manufacturer specification found in the factory service manual for this specific vehicle. Do not guess the value—verify the correct torque before final tightening. Tighten all four mounting nuts (both upper and lower on each side) in this manner.
10
Lower vehicle
Raise vehicle slightly with floor jack to unload jack stands. Remove jack stands from under frame rails. Carefully lower vehicle completely to the ground. Remove wheel chocks.

Reassembly

No disassembly of other components required for this procedure
Ensure all hardware is tightened to proper specification
Links should be replaced as a pair for balanced performance

Verification

Start engine and turn steering wheel lock to lock while stationary to verify no interference with sway bar links
Test drive vehicle at low speed over bumps to confirm no rattling or clunking from rear suspension
Inspect link nuts after 50-100 miles to verify they remain properly torqued
Verify improved handling response and reduced body roll in turns compared to worn links
