Detailed Description

Delphi TC8861 is a suspension control arm for the front left lower position on compatible Mercedes-Benz GLE and GLS models. Delphi applies OE development practices to its aftermarket steering portfolio, using dimensional and material analysis to align the replacement part with the original application. The TC8861 part number is associated with a fitment set that includes the GLE350, GLE450, GLE580, GLS450, and GLS580 from 2020 through 2023. This part cross-references Monroe Shocks & Struts (e.g., 167-330-07-00, A167-330-07-00) for the same application.

Common Repair Uses

• Replaces a corroded or impact-damaged front left lower control arm.

Installation Notes

Verify the vehicle’s exact model and front left lower suspension configuration before ordering. Match the Delphi TC8861 part number to the existing application and confirm fitment against the vehicle identification details. Professional installation and a post-repair alignment are recommended after control arm replacement.
