43330-0N010 43340-0N010 Front Lower Ball Joint Set for Toyota Crown Reiz
Product Emphasis: Genuine Toyota front lower ball joint set engineered to connect the front suspension lower control arm to the steering knuckle on both sides, allowing smooth wheel movement and precise steering control. These critical suspension components support the vehicle's weight while permitting the up-and-down and rotational movement required for steering and suspension travel. Designed as a direct replacement component for the original ball joints, which commonly develop play, excessive wear, or boot damage over time, causing steering looseness, uneven tire wear, and clunking noises.

A worn ball joint can cause steering looseness, clunking noises over bumps, uneven front tire wear, and reduced braking stability.

A: Yes. 43330-0N010 and 43340-0N010 are the genuine Toyota OEM part numbers for the right and left front lower ball joints. They are also available as OEM-quality alternatives from brands including AISIN, Jikiu (JB21003R / JB21003L), 555, and CTR.
Q3: Will this fit my 2010 Toyota Crown?
A: This ball joint set is compatible with Toyota Crown (GRS20#) models from 2008–2012, including the 2010 model year. It also fits Crown, Mark X, and Reiz models listed above. Always verify compatibility using your vehicle's VIN before ordering.
