Product Details

This Delphi rack and pinion bellows is made for Volvo XC90 steering service where the bellows must seal and protect the rack area from road debris, moisture, and contamination. Delphi applies OE-level dimensional and material analysis to help maintain compatibility with the original steering layout on the XC90. This part cross-references Beck/Arnley 103-3069 for the same application.

Common Repair Uses

• Replacing a torn or cracked steering rack bellows
• Addressing grease loss around the rack and pinion assembly
• Reducing contamination entering the steering gear area
• Restoring protection after age-related rubber deterioration
• Servicing steering noise or wear linked to damaged bellows

Installation Notes

Verify the vehicle year and steering configuration before installation. Inspect the rack, tie rod ends, and adjacent seals for wear while the bellows is removed. Confirm the bellows seats correctly on the Volvo XC90 steering gear and that the assembly is secured to prevent air or moisture intrusion.

Quality Assurance

Delphi validates steering components through temperature cycling and salt-spray exposure to evaluate durability in harsh conditions. TBR4446 reflects Delphi's OE-focused approach for the 2003-2014 Volvo XC90 platform.
