The Story
OE-Style Front Right Lower Forward Control Arm
Delphi TC8388 is a suspension control arm and ball joint assembly for the front right lower forward position. It is built for Mercedes-Benz S-Class applications that need a direct-fit replacement with the ball joint, bushings, dust boot, and mounting hardware included.
Delphi applies OE-level dimensional and material analysis to help match the original part’s fit and function. This assembly is pre-greased, uses a clockwise thread direction, and features rubber bushings with a chloroprene rubber dust boot for a premium replacement solution.
Key Features
- Part number: TC8388
- Front right lower forward suspension control arm and ball joint assembly
- Pre-greased for service-ready installation
- Ball joint, bushings, dust boot, and mounting hardware included
- Premium-grade construction with black rubber bushings
- Chloroprene rubber (CR) dust boot and boot material
- Clockwise (right) thread direction
- Non-adjustable design for direct replacement use
- Power steering type application
Detailed Description
Delphi TC8388 is engineered for the front right lower forward suspension position on select Mercedes-Benz S560, S450, S560e, S550, S550e, S600, and Maybach S600 or Maybach S650 models. This assembly is designed to replace the original control arm and ball joint unit with the correct mounting hole diameter, pre-installed components, and OE-focused construction. Delphi’s aftermarket steering and suspension portfolio is backed by extensive testing, including exposure to extreme temperatures and salt spray, to help validate durability in demanding road conditions. This part cross-references Dorman OE Solutions 526-276 for the same application.
Vehicle Fitment
- Fits 2018-2021 Mercedes-Benz S560, front right lower forward.
- Fits 2018-2020 Mercedes-Benz S450, front right lower forward.
- Fits 2019-2020 Mercedes-Benz S560e, front right lower forward.
- Fits 2016-2017 Mercedes-Benz Maybach S600, front right lower forward.
- Fits 2019-2020 Mercedes-Benz Maybach S650, front right lower forward.
- Fits 2014-2017 Mercedes-Benz S550, front right lower forward.
- Fits 2015-2017 Mercedes-Benz S550e, front right lower forward.
- Fits 2015-2017 Mercedes-Benz S600, front right lower forward.
Common Issues This Part Addresses
- Front-end clunking or knocking from a worn lower control arm assembly
- Excessive play from a loose or worn ball joint
- Uneven tire wear caused by suspension geometry wear
- Steering wander or reduced road feel from deteriorated bushings
- Boot damage that can expose the joint to contamination
Installation Notes and Tips
Confirm the front right lower forward position before installation and verify the mounting hole diameter matches the original suspension point. Because this assembly is non-adjustable, proper alignment should be checked after replacement. Inspect adjacent suspension components for wear so the new control arm and ball joint assembly can perform as intended.
Quality Assurance
Delphi uses OE-based engineering, dimensional analysis, and material validation to support fit and durability. The part is tested for extreme temperature exposure and salt-spray resistance as part of Delphi’s validation process for aftermarket steering and suspension components.
