Mercury Trailing Arm eliminates rear axle wiggle, which provides a smoother tracking and a feeling of corner confidence. Mercury began in the late thirties and soon found a niche with midsize cars that rode soft but steered true. Consumers preferred the combination of secluded cabins, neat styling, and affordable prices that Mercury had maintained. Through the years, Mercury continued to add more luxuries to its interiors, smoother suspensions, and a sense of feel versus value that was truthful. Although production ceased in 2011, Mercury remains shorthand for approachable comfort without any fluff. The lineup also featured spacious cabins that dampened road noise and dashboards that were positioned in such a way that people controlled them easily without much fuss. Shakespeareans recall how they drove long highways with minimal fatigue as the vehicles devoured broken pavements like oversized sedans that are a class higher. For the Trailing Arm, the rear axle is connected to the chassis by the simple hinge known as a Trailing Arm, which allows the wheels to lift over bumps without causing the body to move sideways. Trailing Arm configurations are based on paired links and a Panhard rod or a semi-triangular hinge, with each hub steered on a foreseeable arc that does not compromise the trade-offs of cargo volume but rather twists the toe of the stable under load. It reduced brake dive and throttle lift, thus young drivers feel in control when making fast lane changes. Sometimes a Trailing Arm can be constructed to be light but strong and roll over potholes while maintaining tire contact with curvy roadways.

Mercury Trailing Arm Parts and Q&A

Lower Control Arm, Rear
6L2Z-5A649-AE
Q: How to service the trailing arm on Mercury Mountaineer?
A:
Start trailing arm service by disconnecting the toe link and parking brake cable bracket bolt prior to tightening the bolt to 10 Nm (89 lb-inch) at reinstallation. The next step involves taking off the trailing arm bolt then throwing it away but the new bolt must reach a torque of 300 Nm (222 lb-ft) at the curb height. The next step involves taking out the three wheel knuckle bolts together with the trailing arm since these components cannot be salvaged. Installation of the wheel knuckle bolts requires tightening them to 275 Nm (203 lb-ft). Following the inverse of the suspension removal process complete the installation by securing each fastener in its proper orientation then apply recommended torque setting to protect both system functionality and performance.
Trailing Arm, Rear Passenger Side
4M8Z-5500-B
Q: How to service and repair the trailing arm on Mercury Milan?
A:
The process to service or repair the trailing arm requires first disconnecting the wheel spindle and parking brake cable bracket bolt before placing the parking brake cable in position and torquing it to 10 Nm (89 inch lbs.) for reinstallation. The wheel speed sensor harness should be detached from the trailing arm when necessary. The trailing arm requires elevation using an appropriate jack but users must exercise caution because excessive spring compression represents a safety risk to themselves. During installation of the lower arm outboard bolt the suspension needs to be at the bushing fastener tightening position while you tighten it to 101 Nm (74 ft. lbs.). Discard the upper arm outboard bolt after you uninstall it but re-install it with a torque of 110 Nm (81 ft. lbs.) at conditions equal to the removal procedure. Drop the trailing arm while using the jack before removing it. Complete the removal of shock absorber lower bolt and flag nut by tightening them together to 115 Nm (85 ft. lbs.) when installing new components at bushing fastener tightening position. Replace the toe link outboard bolt after tightening it to 110 Nm (81 ft. lbs.) when reinstalling it to its proper location. Remove the two trailing arm forward bolts for replacement before taking out the trailing arm and tighten refurbished bolts to 133 Nm (98 ft. lbs.) during reinstallation. Start the tightening operation only after raising the suspension with a jack and placing it at the bushing fastener tightening position which is reached when the hub center to fender lip distance measures 395 mm (15.55 inch). After fitting the components complete the installation procedure by returning the assembly then check the alignment of the rear end and adjust if needed.
