Keep your rear suspension geometry tight and your tires tracking true with the Mevotech Supreme Lateral Arm (CMS40193). This rear lateral arm drops in as a direct-fit replacement for the 1989-1997 Ford Thunderbird, 1995-1996 Lincoln Mark VIII, and 1989-1996 Mercury Cougar — see the Buyer's Guide tab for engine-level details.
A worn lateral arm can let the rear suspension shift out of position, allowing the alignment to drift. If a failed lateral arm is the cause, replacing it restores the intended location of the rear wheel. Common signs it may need replacing include clunking or rattling from the rear suspension, uneven tire wear, or an alignment that won't stay set — have the cause diagnosed before replacing, since these symptoms can have other sources.
