DESCRIPTION
Note. For information on Continental FWD, see FORD MOTOR CO. AIR SUSPENSION - CONTINENTAL article.
The FWD front suspension is a MacPherson strut type with cast steering knuckles. Shock absorber strut assembly includes a rubber isolated top mount. (Scheme 1)and (Scheme 2). The top of the strut assembly is bolted to the body side apron, with the bottom attached to the steering knuckle.
A pinch joint is designed into knuckle to retain ball joint stud. A forged control arm (lower) is attached to underbody side apron and steering knuckle. On Escort, EXP, Tempo and Topaz models, a stabilizer bar is connected to both control arms and secured to the crossmember. Taurus and Sable models feature tension struts connecting lower control arms to the subframe. A stabilizer bar is connected to the MacPherson struts by stabilizer links attached near the coil spring seats.

FRONT WHEEL BEARINGS
Bearings are cartridge design and are pregreased and sealed. They require no periodic maintenance or adjustment. If bearing is disassembled for any reason, it must be replaced as a unit. No individual service seals, rollers or races are available.
BALL JOINT CHECKING
Raise vehicle so that wheels fall to full down position. Grasp tire by top and bottom edge and move wheel assembly in and out. Any movement between lower end of knuckle and control arm indicates abnormal ball joint wear and requires replacement of lower control arm assembly.
| CAUTION | When hoisting FWD vehicles, ensure hoist adapters are positioned properly. See appropriate JACKING & HOISTING article in WHEEL ALIGNMENT section. |
BALL JOINTS
Ball joints are not replaceable. Replace lower control arm and ball joints as an assembly.
STABILIZER BAR & INSULATORS
Note. When installing insulator bushings on stabilizer bar and in control arms, use only vegetable oil. Any mineral or petroleum based oil or brake fluid will deteriorate rubber bushings.
