Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Tighten up front-end steering and articulation with the Mevotech Supreme control arm and ball joint assembly (CMS86177). This unit installs as the front left (driver's side) upper control arm and drops in as a direct-fit replacement for the 2001-2005 Lexus IS300, locating the wheel while its integrated ball joint allows the suspension and steering to pivot.
A worn IS300 control arm or its ball joint can show up as clunking over bumps, steering wander, looseness or uneven tire wear. If a failed upper control arm or ball joint is the cause, this assembly replaces both in one part. Application-specific Mevotech Supreme engineering adds Labor Saver™ hardware to speed the job.
