Detailed Description

What It Helps Address

• Excessive play in the front lower suspension joint
• Clunking or looseness from a worn ball joint
• Uneven steering response caused by joint wear
• Contamination-related wear from damaged joint protection
• Corrosion-related service issues in exposed suspension components

Installation Notes and Tips

Install in the front lower position only. Verify vehicle configuration before ordering, especially on 1985-1989 Isuzu I-Mark models with Lotus Suspension and the listed heavy-duty exclusions. Because this is a bolt-in design, it is intended for straightforward replacement service, but final fitment should always be confirmed against the vehicle’s suspension layout and notes. The MK9389 is a direct-fit suspension ball joint for the listed applications.

Quality Assurance
