Replace worn front subframe bushings on a 2019-2024 Toyota RAV4 2.5L FWD to restore suspension alignment and eliminate clunking noises.

Warnings

Tools required

Parts

• Front subframe bushing set (4 bushings) × 1 — Use OEM specification
• Subframe mounting bolts (if corroded) × 4 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Loosen all wheel lug nuts while vehicle is on ground
3. Raise vehicle and support securely on jack stands at all four corners
4. Remove front wheels
5. Spray all subframe bolts and suspension fasteners with penetrating oil and allow to soak for 15 minutes
6. Place alignment marks on subframe-to-body mounting points using paint pen for reinstallation reference

Procedure

1. 1

   Disconnect sway bar links
   Remove both front sway bar links from the lower control arms. Hold the ball stud with an Allen key while loosening the nut to prevent spinning. Mark left and right side if links are different lengths.
   Torque spec

   Sway Bar Link Nuts55 Nm (41 lb-ft)
2. 2

   Separate ball joints from knuckles
   Remove the cotter pin and castle nut from both lower ball joints. Use a ball joint separator or pickle fork to separate the ball joint from the steering knuckle. Do not damage the ball joint boot if reusing components.
   Torque spec

   Ball Joint Nut88 Nm (65 lb-ft)
3. 3

   Remove control arm rear bolts
   Remove the rear mounting bolts from both lower control arms where they attach to the subframe. These are through-bolts and may require supporting the control arm while removing. Do not remove the front control arm bolts yet.
   ⚠Support control arm before removing bolt completely to prevent sudden drop.
   Torque spec

   Control Arm Bolts165 Nm (122 lb-ft)
4. 4

   Disconnect steering rack from subframe
   Remove the two steering rack mounting bolts that secure the rack to the subframe. Support the steering rack with wire or a strap to prevent it from hanging by the steering shaft. Do not disconnect steering lines or the intermediate shaft.
   ⚠Do not allow steering rack to hang unsupported. Secure with mechanics wire to frame.
   Torque spec

   Mounting Bolts27 Nm (20 lb-ft)
5. 5

   Support subframe with transmission jack
   Position a transmission jack or subframe support stand under the center of the subframe. Raise slightly to take the weight off the mounting bolts. Ensure the subframe is stable and balanced on the support.
   ⚠️Verify subframe is properly balanced on jack before loosening mounting bolts. Subframe will shift when bolts are removed.
6. 6

   Remove subframe mounting bolts
   Remove all four subframe-to-body mounting bolts. There are two at the front and two at the rear. Remove bolts gradually in a cross pattern while supporting subframe. Note the length and position of each bolt as they may differ.
   ⚠Lower subframe slowly and check for any wiring, hoses, or components still attached before fully lowering.
7. 7

   Lower and remove subframe
   Carefully lower the subframe using the transmission jack. Lower slowly and watch for any obstructions. Once clear, roll the subframe out from under the vehicle and place on a stable work surface. The control arms will still be attached at the front pivot points.
   ⚠️Subframe is heavy and awkward. Use proper lifting technique and get assistance if needed.
8. 8

   Remove old bushings
   Inspect all four subframe bushings for wear, cracking, or separation. Mark the orientation of the old bushings before removal. Use a hydraulic press or bushing removal tool to press out the old bushings from the subframe. Clean the bushing bores thoroughly with a wire brush and solvent.
   ℹ️Note the orientation of bushings. They have a specific directional alignment and may have alignment marks or voids that must face a particular direction.
9. 9

   Install new bushings
   Apply a thin coat of soapy water or bushing installation lubricant to the new bushings (do not use petroleum-based lubricants). Align bushings according to manufacturer markings or match the orientation of the old bushings. Press new bushings into subframe using hydraulic press or bushing driver kit. Ensure bushings are seated fully and evenly.
   ⚠Press bushings in straight to avoid damage. Bushings must be fully seated against shoulder in bore.
10. 10

    Reinstall subframe
    Position the subframe on the transmission jack and roll under vehicle. Align subframe to the alignment marks made during disassembly. Raise subframe into position and start all four mounting bolts by hand. Torque subframe bolts to specification in a cross pattern.
    ⚠Verify subframe is aligned properly with body mounting points before tightening bolts. Misalignment will cause premature bushing wear.
11. 11

    Reconnect steering rack
    Remove support wire from steering rack and align rack to subframe mounting points. Install steering rack mounting bolts and torque to specification. Verify steering rack boots are not twisted or damaged.

    Mounting Bolts27 Nm (20 lb-ft)
12. 12

    Reconnect control arms
    Align control arms to rear mounting points on subframe. Install rear control arm through-bolts but do not torque yet. These must be torqued with vehicle weight on wheels. Reconnect ball joints to steering knuckles and install castle nuts. Torque ball joint nuts and install new cotter pins.
    ⚠Do not fully torque control arm bolts yet. These require vehicle weight on suspension.

13. 13

    Reconnect sway bar links
    Install sway bar links to control arms. Hold ball stud with Allen key while tightening nuts. Torque to specification. Ensure links are not twisted during installation.
    Torque spec

    Sway Bar Link Nuts55 Nm (41 lb-ft)
14. 14

    Install wheels and lower vehicle
    Install front wheels and hand-tighten lug nuts in star pattern. Lower vehicle until wheels just touch ground but jack stands still support weight. Torque wheel lug nuts to specification in star pattern. Remove jack stands and lower vehicle completely to ground.
    Torque spec

    Wheel Lug Nuts136 Nm (100 lb-ft)
15. 15

    Final torque control arm bolts
    With vehicle weight fully on wheels, torque the control arm rear mounting bolts to final specification. This step is critical for proper bushing life. Rock vehicle side to side a few times before final torquing to settle suspension.
    ⚠This step must be performed with full vehicle weight on suspension. Failure to do so will cause premature bushing failure and misalignment.

Reassembly

1. Verify all fasteners are torqued to specification
2. Check that all cotter pins are installed in ball joint castle nuts
3. Verify steering rack is properly secured and boots are not damaged
4. Confirm no tools or parts were left under vehicle

Verification

• Test drive vehicle and verify no clunking or abnormal noises from front suspension
• Check steering for proper operation and no binding
• Verify vehicle tracks straight with no pulling to either side
• Schedule four-wheel alignment within 50 miles of completing this repair, as subframe removal will affect alignment settings
• Inspect subframe bolts after 100 miles for proper torque retention
