Key Features
Connects the rear subframe to the knuckle as part of the wheel-guiding suspension linkage.
Provides a replacement option when inspection identifies wear or damage in the upper aft link.
For matching 2021–2025 Model S/X Palladium applications. Confirm the full OE reference before ordering.
Choose RH 1420426-00-B or LH 1420428-00-B to match the required mounting orientation.
Sold individually, so you can order the side or sides specified for the repair.
Why Choose This Product ?
A rear knock can make ordinary driving frustrating, but several components can produce it. When inspection traces wear or excessive movement to the upper aft link, replacing the affected assembly addresses that identified component rather than buying parts by sound alone.
If rear tires are wearing unevenly, have the alignment and suspension checked together. Where a worn upper aft link forms part of the diagnosis, include its replacement in the repair plan before the technician completes the required alignment work.
Rear upper aft, upper fore and toe links serve different positions. This listing identifies the upper aft assembly and separates LH 1420428-00-B from RH 1420426-00-B, helping turn the repair estimate into the correct part selection.

Fitment & Ordering
For 2021–2025 Tesla Model S and Model X Palladium vehicles only when the selected reference matches the vehicle-specific parts information. Model and year alone do not establish compatibility. Have the installer confirm the production version, market and steering configuration before ordering.
Not listed for pre-Palladium Model S/X, Model 3 or Model Y.
Do not order by model year alone or assume the two sides are interchangeable.
Installation
Professional installation is required. This Model S LH (left-hand) replacement overview is not a complete workshop procedure. For RH (right-hand) work, use the instructions applicable to that side and vehicle. Obtain the required tightening specifications before starting.
Lift and access: Follow the vehicle-specific lifting procedure, support the vehicle and remove the LH rear wheel.
Release the subframe connections: Remove the two bolts securing the link to the rear subframe. Detach the harness clip from the knuckle and release the wiring from its bracket.
Remove the link: Remove its knuckle-side bolt, then withdraw the assembly carefully without damaging the harness.
Position and attach: Fit the replacement at the knuckle, inserting its bolt without final tightening. Install the two subframe bolts and tighten them to their specified torque.
Resecure the harness: Reattach the harness clip to the knuckle and seat the wiring in its bracket.
Handle the rotor retaining bolt: If fitted, remove and discard the bolt securing the brake rotor to the hub; no replacement is installed in this LH procedure. This does not refer to the wheel fasteners.
Finish link tightening: Tighten the knuckle-side bolt to its specified torque and mark the connection with a paint pen.
Refit and check: Install the LH rear wheel using the wheel procedure, lower the vehicle and consult the alignment requirements to determine the necessary checks or adjustments.
FAQ
Q: Which number is left and which is right?
LH 1420428-00-B is the left-hand option. RH 1420426-00-B is the right-hand option. Vehicle sides are identified when facing forward.
Q: Will this stop rear suspension knocking?
Replacement can address a diagnosed fault in this link. Knocking may also come from other components, so inspection is necessary before ordering.
Q: Will it correct uneven tire wear?
Not by itself in every case. Tire wear can involve alignment, tire condition and several suspension components. Replace this link only when its condition forms part of the diagnosis.
Q: Do I receive both sides?
No. Each purchase includes one assembly in the selected side.
Q: Are these adjustable camber arms?
This listing does not offer an adjustable camber feature. Do not select it as a camber correction or lowering modification.
Q: Are the OE references proof of genuine Tesla manufacture?
No. This is a new aftermarket replacement. The references identify the corresponding part for matching and do not establish genuine Tesla manufacture.
