Description

Restore the handling, stability, and rear suspension performance of your Tesla with the MEYLE Rear Upper Aft Link, a high-quality replacement control arm designed for the rear upper suspension of the Tesla Model 3 and Model Y.

Also referred to as a rear upper control arm, rear upper lateral link, or rear upper aft link, this suspension component helps locate the rear wheel assembly and maintain the vehicle’s rear suspension geometry.

The MEYLE 70-16 050 0012 is designed for applications using Tesla OE reference 1188423-00-A, along with additional OE revisions including 1044423-00-G, 1044423-00-H, 1288423-00-A, 1344426-00-C, and 1344426-00-D.

The control arm is constructed from steel and includes the integrated suspension bushing, providing a complete arm assembly that can replace a worn or damaged factory component.

A worn rear upper control arm or bushing can contribute to rear-end clunking, instability, alignment changes, and uneven tire wear. Replacing the arm can help restore the intended rear suspension geometry and driving feel.

Important Fitment Note

Tesla has used multiple revisions of rear suspension components throughout Model 3 and Model Y production.

Verify the OE number on your original control arm before ordering.

For newer-production vehicles or vehicles with updated rear suspension components, VIN-based fitment verification is recommended.

What Does the Rear Upper Aft Link Do?

The rear upper aft link is part of the Tesla’s multi-link rear suspension.

It helps locate the rear wheel assembly and maintain the correct relationship between the wheel hub, suspension, and vehicle chassis.

The control arm works with the other rear suspension links to maintain proper wheel alignment and suspension geometry during acceleration, braking, cornering, and suspension movement.

A properly functioning rear upper link contributes to:

• Stable rear-end handling
• Proper suspension geometry
• Consistent wheel alignment
• Predictable cornering behavior
• Controlled rear wheel movement
• Proper tire contact with the road

Signs of a Worn Rear Upper Aft Link

The integrated bushing is subjected to constant suspension movement, road impacts, and vehicle load. As the bushing or arm wears, drivers may experience:

• Rear suspension clunking
• Knocking over bumps
• Rear-end instability
• Changes in handling
• Uneven tire wear
• Alignment changes
• Excessive rear suspension movement
• Less predictable cornering
• Creaking or other suspension noises

If one rear control arm shows significant wear, the opposite side should also be inspected.

Integrated Bushing

The MEYLE 70-16 050 0012 is supplied as a complete control-arm assembly with the suspension bushing installed.

This eliminates the need to press the old bushing out of the original arm and install a separate replacement bushing.

MEYLE also offers the replacement bushing separately as MEYLE 70-14 710 0021, which cross-references Tesla OE 1188423-00-A. That separate bushing is listed as a rear axle left/right, upper, center application and is recommended for replacement in pairs.

Individual Part Pair Replacement Recommended

This product is sold individually.

One MEYLE 70-16 050 0012 control arm is supplied per package.

However, MEYLErecommends replacement in pairs.

For a complete rear suspension repair, customers should purchase two units when replacing both sides.

EVANNEX Ordering Guide

Replacing one side:
Order 1 MEYLE 70-16 050 0012

Replacing both sides:
Order 2 MEYLE 70-16 050 0012

The same part is used on the left and right sides.

Installation

Professional installation is recommended.

Because this component is part of the rear suspension geometry, correct installation and torque procedures are important.

After replacing a rear suspension control arm, a professional four-wheel alignment is strongly recommended. Replacing suspension links can change rear camber and toe settings, and proper alignment helps prevent uneven tire wear and maintain predictable handling.

Tesla suspension fasteners may have specific torque and tightening procedures. Follow the applicable Tesla service procedure for your vehicle.
