This procedure covers the removal and replacement of the front sway bar links on a 2019-2024 Toyota RAV4 with the 2.5L I4 engine, a common maintenance item to address clunking noises over bumps.

Warnings

Tools required

Parts

• Front sway bar link (left) × 1 — 48820-42020 or equivalent
• Front sway bar link (right) × 1 — 48820-42020 or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Loosen front wheel lug nuts while vehicle is on ground (do not remove)
4. Raise front of vehicle with floor jack at manufacturer-approved jacking points
5. Support vehicle securely on jack stands under the front subframe or pinch welds
6. Remove front wheels completely

Procedure

1. 1

   Inspect sway bar link condition
   Locate the sway bar link connecting the lower control arm to the sway bar. Check the ball joint boots for tears and attempt to move the link by hand to confirm excessive play. This confirms replacement is needed.
2. 2

   Apply penetrating oil if needed
   If nuts show corrosion, spray penetrating oil on both the upper nut (sway bar side) and lower nut (control arm side). Allow to soak for 15-30 minutes before proceeding.
3. 3

   Remove upper sway bar link nut
   Insert a 6mm Allen key into the top of the sway bar link shaft to hold it from spinning. Using a 14mm wrench, remove the upper nut that connects the link to the sway bar. If the ball joint spins even with the Allen key held, use locking pliers on the ball joint shaft just below the boot.
4. 4

   Remove lower sway bar link nut
   Insert the 6mm Allen key into the bottom of the sway bar link shaft. Using a 14mm wrench, remove the lower nut that connects the link to the lower control arm. Support the link with your hand as you remove the final threads to prevent it from falling.
   ⚠The link may be under slight tension from the sway bar. Keep fingers clear of pinch points between the link and mounting brackets.
5. 5

   Remove sway bar link
   Pull the sway bar link down and away from the sway bar, then maneuver it out through the suspension components. Note the orientation and any washers or bushings for reinstallation.
6. 6

   Clean mounting surfaces
   Use a wire brush to clean the sway bar and control arm mounting holes, removing rust, dirt, and old thread lock compound. This ensures proper seating of the new link and accurate torque readings.
7. 7

   Install new sway bar link
   Position the new sway bar link with the ball joint studs pointing up through the control arm hole and down through the sway bar hole. Install washers and nuts finger-tight on both ends. Ensure the link is properly seated in both mounting locations before tightening.
8. 8

   Torque sway bar link nuts
   Hold each ball joint shaft with the 6mm Allen key to prevent spinning. Torque both the upper and lower nuts to specification using a torque wrench and 14mm socket. Verify the Allen key was held throughout torquing to ensure accurate readings.
   Torque spec

   Sway Bar Link Nuts55 Nm (41 lb-ft)
9. 9

   Repeat for opposite side
   Perform steps 1-8 on the opposite side sway bar link. Both links should be replaced as a pair to maintain balanced suspension performance and prevent premature failure of the new link.

Reassembly

1. Reinstall front wheels and hand-tighten lug nuts in a star pattern
2. Lower vehicle from jack stands using floor jack
3. Remove jack stands and lower vehicle completely to ground
4. Torque wheel lug nuts to 103 Nm (76 lb-ft) in a star pattern with wheels on ground
5. Remove wheel chocks

Verification

• Test drive vehicle over small bumps at low speed and listen for clunking noises from front suspension
• Perform a visual inspection under the vehicle to confirm sway bar link nuts are secure and links are properly aligned
• Check that there is no excessive play in the new sway bar links by attempting to move them by hand with the vehicle raised
• Verify steering feels stable and centered during normal driving
