Rear Left Lower Lateral Arm for 2015-2018 BMW X4 & More - Delphi TC3259

Keep the rear suspension geometry tight and the ride quiet with the Delphi Lateral Arm (TC3259), the rear left lower rearward link that helps locate the wheel and control its position through every bump and turn. It installs as a direct-fit replacement for the 2009-2017 BMW X3 and 2015-2018 BMW X4 — see the "Vehicles it fits" section for engine-level fitment.

Delphi applies its OE steering and suspension expertise to this aftermarket arm, backing it with the same testing philosophy used on parts fitted to millions of vehicles worldwide:

• Tested to the extreme: validated below -40°C and above 120°C and exposed to 720 hours of salt spray, with extensive dimensional and material analysis for close OE compatibility.
• 100% inspected: each arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
• Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
• Complete job: includes the necessary accessories for the installation.

Signs this arm may need replacing include clunking over bumps, uneven rear tire wear, or loose, wandering handling — diagnose the cause before replacing, since worn bushings or ball joints elsewhere can produce similar symptoms.
