Replace worn subframe bushings on the front suspension subframe to restore handling precision and reduce vibration and noise.

Warnings

Tools required

Parts

• Front subframe bushing set (4 bushings) × 1 — Use OEM specification
• Ball joint castle nut (if cotter pin type) × 2 — Use OEM specification

Preparation

1. Park vehicle on level ground and apply parking brake
2. Loosen front wheel lug nuts while vehicle is on ground
3. Raise front of vehicle and support securely on jack stands at manufacturer-specified lift points
4. Raise rear of vehicle and support on jack stands to achieve level working height
5. Remove both front wheels
6. Spray all subframe bolts, ball joint nuts, and sway bar link nuts with penetrating oil and allow to soak
7. Place drain pan under work area to catch any residual fluid from power steering lines if equipped

Procedure

1. 1

   Disconnect sway bar links
   Locate the sway bar links connecting the sway bar to the lower control arms on both sides. Hold the ball stud with an Allen key to prevent spinning, then remove the lower sway bar link nuts. Separate the links from the control arms.
   Torque spec

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

   Disconnect lower ball joints
   Remove the cotter pins if present, then loosen and remove the ball joint castle nuts from both lower control arms. Use a ball joint separator tool to separate the ball joints from the steering knuckles. Do not hammer directly on the joint - use the proper separator tool to avoid damage.
   ⚠Ball joint taper fit requires proper separator tool - do not use a pickle fork style tool as it will damage the boot
   Torque spec

   Ball Joint Nut84 Nm (62 lb-ft)
3. 3

   Support steering rack and disconnect from subframe
   Support the steering rack with wire or a secondary jack. Remove the steering rack mounting bolts that attach to the subframe. Lower the rack slightly but keep it supported - do not allow it to hang by the steering shaft.
4. 4

   Disconnect engine mounts from subframe
   Locate the lower engine mount and transmission mount attachment points to the subframe. Remove the through-bolts or mounting nuts that connect these mounts to the subframe. The engine weight is supported by the upper mount brackets, but verify engine is stable.
5. 5

   Mark and support subframe
   Use paint or a marker to mark the exact position of the subframe relative to the body at all four mounting points. Position a transmission jack or subframe support jack under the center of the subframe. Raise jack until it just contacts and supports the subframe weight.
   ⚠Alignment marks are critical for proper reinstallation - misalignment will affect steering geometry and tire wear
6. 6

   Remove subframe mounting bolts
   Locate all four subframe-to-body mounting bolts (two front, two rear). Using a breaker bar and socket, remove all four mounting bolts. Slowly lower the subframe jack while guiding the subframe clear of the steering rack and brake lines. Lower the subframe completely and remove from under vehicle.
   ⚠️Subframe is heavy and has sharp edges - use caution when lowering and removing to avoid injury
7. 7

   Remove old bushings from subframe
   Place subframe on a sturdy work surface. Mark the orientation of each bushing before removal. Using a bushing press kit or hydraulic press with appropriate adapters, press out all four old bushings from the subframe. Clean the bushing bores thoroughly with a wire brush and inspect for damage or cracks.
8. 8

   Install new bushings
   Apply a light coat of soapy water or bushing lubricant (not grease) to the outer surface of the new bushings and the subframe bores. Align the bushing orientation marks or voids correctly according to OEM specifications. Using the bushing press and proper sized adapters, press each new bushing into the subframe until fully seated. Ensure bushings are pressed in straight and to the correct depth.
   ⚠Bushing orientation is critical - most bushings have voids that must align with the direction of movement for proper function
9. 9

   Reinstall subframe to vehicle
   Place subframe on the transmission jack and raise into position under the vehicle. Align the subframe with the alignment marks made during removal. Guide the subframe into position, ensuring clearance from steering rack and brake lines. Hand-thread all four subframe mounting bolts. Align subframe precisely with marks, then torque all four mounting bolts to specification. Remove the support jack.
10. 10

    Reconnect engine mounts
    Reinstall the engine mount and transmission mount through-bolts or mounting nuts to the subframe. Torque to manufacturer specifications. Ensure mounts are properly aligned and not twisted.
11. 11

    Reconnect steering rack
    Raise the steering rack back into position on the subframe. Install the steering rack mounting bolts and torque to specification. Remove the support wire or jack.
12. 12

    Reconnect lower ball joints
    Clean the ball joint tapers and steering knuckle bores with a wire brush. Insert the ball joint studs into the steering knuckles and install new castle nuts. Torque the ball joint nuts to 84.0 Nm (62.0 lb-ft). Install new cotter pins if applicable and bend to secure.
    Torque spec

    Ball Joint Nut84 Nm (62 lb-ft)
13. 13

    Reconnect sway bar links
    Connect the sway bar links to the lower control arms. Hold the ball stud with an Allen key and install the lower nuts. Torque to 55.0 Nm (41.0 lb-ft).
    Torque spec

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

    Reinstall wheels and lower vehicle
    Install both front wheels and hand-tighten lug nuts in a star pattern. Lower the vehicle until the wheels just contact the ground but the suspension is not fully loaded. Torque wheel lug nuts to 129.0 Nm (95.0 lb-ft) in a star pattern. Fully lower the vehicle to the ground.
    Torque spec

    Wheel Lug Nuts129 Nm (95 lb-ft)
15. 15

    Final torque control arm bolts
    With the vehicle weight fully on the wheels at normal ride height, torque all control arm mounting bolts to 165.0 Nm (122.0 lb-ft). This must be done with the suspension at normal ride height to prevent bushing bind.
    ⚠Control arm bolts MUST be torqued with vehicle at normal ride height - torquing while suspended will preload bushings and cause premature failure
    Torque spec

    Control Arm Bolts165 Nm (122 lb-ft)

Reassembly

1. Ensure all fasteners are torqued to specification with vehicle at proper ride height
2. Verify all suspension components move freely without binding
3. Double-check that all cotter pins are installed and properly bent
4. Inspect for any missed connections or loose hardware

Verification

• Test drive vehicle and verify elimination of clunking or vibration that prompted bushing replacement
• Check for proper steering feel and return to center
• Listen for any unusual noises during acceleration, braking, and turning
• Schedule a professional alignment check within 100 miles - subframe removal requires alignment verification
• Re-torque all critical fasteners after first 50 miles of driving
