Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS30121
Bring solid, predictable steering geometry back to your front suspension with the Mevotech Supreme control arm (P/N CMK8596), a front left upper control arm with an integrated ball joint that drops in as a direct-fit replacement for the 1989-1997 Ford Thunderbird and 1989-1997 Mercury Cougar. It locates the wheel and carries the ball joint that lets the steering knuckle pivot and travel, so if a worn original is behind clunks over bumps, loose or wandering steering, or uneven tire wear, this replaces it in one unit.
This Mevotech Supreme suspension control arm is engineered in-house with application-specific upgrades and Labor Saver™ design details that speed the install.

What vehicles does this Mevotech Supreme control arm fit?
It's a direct-fit replacement for the 1989-1997 Ford Thunderbird and 1989-1997 Mercury Cougar, in the front left upper position. See the Buyer's Guide tab to confirm your exact vehicle.
Is this a control arm and ball joint assembly?
Yes. The ball joint is integrated into the arm, so this single unit replaces both the front left upper control arm and its ball joint at once.
Does it come with the ball joint nut and a grease fitting?
Yes. A part-specific locking nut is provided to speed the ball joint installation, and an SAE grease fitting is included to make servicing easier.
What are signs my Ford Thunderbird control arm or ball joint may need replacing?
Clunking or knocking over bumps, loose or wandering steering, popping when turning, and uneven tire wear can point to a worn arm or ball joint. Diagnose the cause before replacing.
What is this Mercury Cougar control arm made of?
It uses forged steel construction with patented sintered bearings and a protective surface treatment that helps resist corrosion.
