Replace worn subframe bushings on the front subframe assembly to restore proper suspension alignment and reduce noise and vibration.

Warnings

Tools required

Parts

• Front subframe bushings (set of 4) × 1 — Use OEM specification
• Ball joint cotter pins × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Loosen front wheel lug nuts while vehicle is on ground
3. Raise front of vehicle and support securely on jack stands under manufacturer-specified lift points
4. Remove both front wheels
5. Spray all subframe bolts, control arm bolts, and ball joint nuts with penetrating oil and allow to soak for 15-30 minutes
6. Place additional jack stands under rear of vehicle for stability during subframe removal

Procedure

1. 1

   Disconnect sway bar links
   Remove both front sway bar link nuts from the sway bar using a wrench while holding the shaft with an Allen key to prevent spinning. Disconnect links from sway bar and allow control arms to hang free.

   Sway Bar Link61 Nm (45 lb-ft)
2. 2

   Separate ball joints from knuckles
   Remove cotter pins from both ball joint castle nuts. Loosen ball joint nuts but do not remove completely. Use ball joint separator tool to break the taper between ball joint stud and steering knuckle. Once separated, remove nuts completely and lower control arms away from knuckles.
   ⚠Keep nut threaded on a few turns before using separator tool to prevent sudden separation and component damage.

3. 3

   Remove steering rack mounting bolts
   Locate the steering rack where it mounts to the subframe. Remove the two steering rack mounting bolts but leave rack hanging supported by steering shaft. Do not disconnect hydraulic lines or steering shaft.
4. 4

   Support subframe with transmission jack
   Position hydraulic transmission jack or subframe support directly under the center of the subframe. Raise jack until it just contacts subframe and supports the weight. Ensure jack is centered and stable before proceeding.
   ⚠️Subframe will drop when bolts are removed. Jack must be securely positioned and rated for the weight.
5. 5

   Mark subframe alignment position
   Using a paint marker or scribe, mark the position of the subframe relative to the body mounting points on all four corners. This ensures proper alignment during reinstallation and prevents alignment issues.
6. 6

   Remove subframe mounting bolts
   Locate all four main subframe mounting bolts (two front, two rear). Using a breaker bar, loosen all four bolts but do not remove completely. Remove bolts in a cross pattern to maintain even pressure. Slowly lower the transmission jack while guiding the subframe down, watching for any caught wiring or components.
   ⚠Check for brake lines, ABS wiring, or other components that may be routed near subframe before lowering.
7. 7

   Remove control arm bolts
   With subframe lowered and accessible, remove the front and rear control arm mounting bolts from both sides. Note the orientation of any washers or spacers for reinstallation. Control arms can remain attached to subframe during bushing replacement.
   Torque spec

   Control Arm Bolts165 Nm (122 lb-ft)
8. 8

   Remove subframe from vehicle
   With all mounting bolts removed, carefully lower the transmission jack and roll the subframe assembly out from under the vehicle. Move to a suitable work area with press access. Clean the subframe mounting areas with wire brush to remove rust and debris.
9. 9

   Press out old bushings
   Using a hydraulic press or bushing press tool, press out all four subframe bushings from their mounting locations. Note the orientation and depth of original bushings. Clean bushing bores thoroughly with wire brush and inspect for cracks or damage to subframe.
   ⚠Ensure press force is applied evenly to avoid damaging subframe bore. Use proper size mandrels or sockets.
10. 10

    Install new bushings
    Apply light coating of soapy water or bushing lubricant to new bushings (do not use petroleum-based lubricants). Press new bushings into subframe bores using hydraulic press, ensuring they are fully seated and aligned to match original orientation and depth. Bushings should be flush or slightly recessed as per manufacturer specification.
11. 11

    Reinstall subframe assembly
    Position subframe on transmission jack and roll under vehicle. Raise subframe into position, aligning with the reference marks made during disassembly. Start all four main subframe mounting bolts by hand, ensuring threads engage properly. Install steering rack mounting bolts hand-tight.
12. 12

    Torque subframe and steering components
    Torque all four main subframe mounting bolts to manufacturer specification (typically 150-180 Nm, verify in service manual as not provided in torque list). Tighten in cross pattern. Torque steering rack mounting bolts per specification. Remove transmission jack once subframe is secured.
13. 13

    Install control arms and ball joints
    Install both control arm mounting bolts hand-tight at this stage (final torque must be done with vehicle weight on suspension). Raise control arms to steering knuckles and install ball joint studs into tapers. Install ball joint nuts and torque to specification, then install new cotter pins through castle nut and stud.

    Reconnect sway bar links
    Connect sway bar links to sway bar on both sides. Hold shaft with Allen key and torque nuts to specification.
    Torque spec

    Sway Bar Link61 Nm (45 lb-ft)
15. 15

    Install wheels and perform final torque
    Install both front wheels and hand-tighten lug nuts. Lower vehicle until suspension is at normal ride height with full vehicle weight on wheels. Torque all control arm bolts to specification in this loaded position. Raise vehicle slightly, torque wheel lug nuts in star pattern, then lower vehicle completely.
    ⚠Control arm bolts MUST be torqued with vehicle weight on suspension or premature bushing failure will occur.
    Torque spec

    Control Arm Bolts165 Nm (122 lb-ft)

    Wheel Lug Nuts136 Nm (100 lb-ft)

Reassembly

1. Verify all fasteners are torqued to specification, especially control arm bolts which must be torqued at ride height
2. Confirm new cotter pins are properly installed and bent on ball joint castle nuts
3. Check that steering rack moves freely and no binding occurs through full range of motion

Verification

• Start engine and turn steering wheel lock to lock while stationary to verify no binding or interference
• Test drive vehicle at low speed in safe area and verify no clunking noises from front suspension
• Schedule four-wheel alignment immediately after subframe bushing replacement as alignment will be affected
• Recheck all torque specifications after 50-100 miles of driving
