Delphi TA5520 Steering Idler Arm

Delphi TA5520 Steering Idler Arm

The Delphi TA5520 steering idler arm is a standard replacement part for restoring steering linkage support on select Nissan Frontier models. Built with a forged arm and a greaseable design, it is engineered for consistent fitment and serviceability in demanding steering applications.

Key Features

• Forged construction for strength and durability
• Pre-greased for initial installation readiness
• Grease fitting included for future maintenance
• Black finish
• Taper-style arm attachment
• 3 bracket holes with 0.5 in. / 12.8 mm mounting hole diameter
• Standard replacement grade

Detailed Description

Delphi applies OE-focused dimensional and material analysis to its aftermarket steering portfolio, helping support proper fit and function. The TA5520 steering idler arm is built for 1998-2004 Nissan Frontier applications and is designed to match the steering geometry used in those vehicles. Delphi subjects steering components to extreme temperature exposure and extended salt-spray testing to evaluate durability in harsh conditions. This part cross-references Beck/Arnley 101-4738 for the same application. Delphi TA5520 is a practical choice when replacing a worn steering idler arm on a Nissan Frontier, especially when steering play or linkage looseness has developed.

What This Part Helps Address

• Steering wheel looseness caused by wear in the idler arm
• Front-end wandering or reduced steering stability
• Excessive play in the steering linkage
• Uneven steering response from a worn support point
• Noisy or rough steering feel from degraded steering components

Installation Notes and Tips

Fits 1998-2004 Nissan Frontier, N/A. Verify bracket hole spacing, taper engagement, and mounting dimensions before installation. Because this part is greaseable, service the fitting after installation and follow the vehicle service procedure for steering linkage inspection and alignment checks. The Delphi TA5520 should be installed as part of a complete steering inspection when replacing worn linkage components on a Nissan Frontier.

Quality Assurance

Delphi uses OE-based engineering practices for its steering parts and validates components through dimensional and material analysis, temperature cycling below -40 C and above 120 C, and 720 hours of salt-spray exposure. These checks are used to support consistent aftermarket performance for the TA5520.
