Frequently Asked Questions (FAQs)

Q1: What is a rear lower suspension trailing arm?
A: A trailing arm is a suspension link that connects the rear wheel hub to the chassis, helping to control wheel motion and absorb forces from acceleration, braking and bumps — essential for stable ride quality.

Q2: How do I know if it needs replacing?
A: Common signs of a worn trailing arm include unusual noises from the rear suspension, uneven tyre wear, loose feeling when driving or instability during cornering — often due to worn bushes or arm damage.

Q3: Is this compatible with my RAV4?
A: This kit is designed for Toyota RAV4 models that use the specified OEM references (e.g., 48720-42030/48710-42010) — typically early RAV4 Mk II (2000-2005) petrol and diesel variants. Always check part numbers or vehicle fitment before ordering.

Q4: Can I install this myself?
A: Installation requires suspension access and correct torque settings; while an experienced DIYer with tools can fit it, professional installation is recommended for safety and alignment accuracy.

Q5: Do I need wheel alignment after replacing the trailing arm?
