Delphi TA3170 Steering Tie Rod End - Inner

Delphi TA3170 Inner Tie Rod End

Delphi TA3170 is a standard replacement inner steering tie rod end built for BMW steering systems that require precise linkage between the rack and outer tie rod. It uses a high-strength steel housing and Delphi OE-based dimensional and material analysis to support proper fit and steering response.

Compatible with select BMW 2 Series, 3 Series, 4 Series, and M models, including BMW 320i, 328i, 335i, 430i, and M240i applications. This Delphi TA3170 inner tie rod end is engineered for direct replacement service where the original inner joint has wear, looseness, or play.

Key Features

• Inner steering tie rod end for BMW steering repair
• Standard replacement grade
• High-strength steel housing
• Male-to-male end configuration
• No grease fitting, dust boot, or mounting hardware included
• Non-greaseable design for maintenance-free service

Detailed Description

Delphi TA3170 is built for the inner position in the steering linkage and is intended to restore the connection between the steering rack and the outer tie rod. Delphi applies OE engineering practices to its aftermarket steering portfolio, including dimensional and material analysis to help ensure proper compatibility with the original steering geometry. The part is tested across extreme temperature ranges and exposed to extended salt spray conditions to evaluate durability in demanding environments.

This part cross-references MOOG Chassis Products ES800943A for the same application. It also cross-references Beck/Arnley 101-7999 for the same application.

What It Helps Address

• Steering wheel play caused by a worn inner tie rod end
• Clunking or looseness in the front steering linkage
• Uneven steering response from excessive joint wear
• Inspection failure related to steering component wear
• Restoration of steering rack-to-tie rod connection on BMW vehicles

Verify steering alignment after installation and inspect related components such as the outer tie rod end, rack boots, and front suspension wear points. Because this is an inner steering component, correct torque and alignment procedures are important for proper steering feel and tire wear control.

Quality Assurance

Delphi uses OE safety technology and aftermarket steering validation practices to support consistent fit and performance. The part is evaluated for temperature extremes below -40 degrees C and above 120 degrees C, along with 720 hours of salt spray exposure, to help confirm durability in harsh operating conditions.
