ISUZU D-MAX Front Lower Arm Bush 8-97947087-0 OEM Fit

The lower arm bush is the elastic pivot element connecting the control arm to the vehicle body in the suspension system. It absorbs road impacts and suspension vibration through the elastic deformation of rubber, preventing direct metal-to-metal contact while constraining the arm’s motion trajectory to keep front wheel alignment parameters (caster, camber, toe) within design limits.

The 8-97947087-0 bush features a rubber-to-metal composite construction: the 16 mm inner diameter accommodates the arm bolt, the 47–55 mm outer diameter (measurement varies by brand) is pressed into the arm or subframe bore, and the 65 mm length spans the pivot width. This bush fits all D-MAX engines (4JK1 / 4JJ1 / 4JH1, etc.) and is a high-frequency replacement item in front suspension overhauls or noise remediation.

Replace the bush when any of these symptoms appear:

• “Clunking” or metallic knocking from the front suspension over bumps — aged or torn rubber creates clearance between the arm and chassis, causing metal-to-metal contact.
• Steering wheel vibration, vague road feel, or high-speed instability — the bush loses elasticity and cannot effectively absorb road excitation, causing dynamic instability in front alignment geometry.
• Abnormal front tire wear (cupping, scalloping) — a loose arm pivot allows front alignment parameters to change during driving.
• Vehicle pulling during braking or acceleration — uneven bush wear on left/right sides causes asymmetric suspension geometry.
• Visible cracks, tears, permanent deformation, or metal sleeve separation on the bush — the bush has structurally failed and must be replaced immediately.
• Abnormal wear on the arm bolt or bush bore — metal-to-metal friction after bush failure accelerates wear on the arm and subframe bore.

1. 1Preparation: Raise and support the vehicle at the front axle/subframe. Remove the front wheels. Disconnect the lower arm bolts and links.
2. 2Removal: Extract the old bush using a dedicated puller or press. Clean the bush bore in the arm and subframe.
3. 3Inspection: Inspect the arm and subframe bore for scoring, deformation, or excessive wear. Check the arm ball joint, upper arm bushes, and stabilizer links.
4. 4Installation: Use a dedicated press tool to press the new bush squarely into the arm/subframe bore until fully seated. Never hammer or pry.
5. 5Reassembly: Install the lower arm and links, torquing the bolts to specification (final tightening is recommended with the vehicle at normal ride height).
6. 6Wheel Alignment: Perform a professional wheel alignment to restore front alignment parameters.
7. 7Road Test: Perform a road test to confirm no front suspension noise, no steering play, and no pulling.

• Every 10,000 km: Check front suspension for abnormal noise; inspect bushes for cracks or deformation.
• Every 40,000–50,000 km: Inspect bush elasticity and metal bonding; replace if aged or torn.
• When abnormal front tire wear or steering play is detected: Inspect the lower arm bushes and ball joints immediately.
