Detailed Description

This Dorman suspension ball joint, part number 539-930, is made for front lower suspension service on 2011-2017 Lexus CT200h, 2010-2015 Toyota Prius, and 2012-2015 Toyota Prius Plug-In. The bolt-in mounting style, three mounting holes, and threaded body support OE-style replacement on the specified vehicles.

What This Part Helps Address

• Front suspension looseness or play at the lower control arm connection
• Clunking or knocking noises from the front end over bumps
• Uneven tire wear related to worn ball joint movement
• Steering instability or wandering caused by joint wear
• Service replacement for a damaged or corroded original ball joint

Installation Notes and Tips

Verify vehicle application by year, make, model, and front lower position before installation. The tapered stud uses a castle nut and cotter pin hole, so follow the vehicle service procedure for proper torque and final fastener retention. Because this is a non-greaseable design, routine lubrication is not required. For best results, inspect related suspension components such as control arms, bushings, and alignment settings during service.

Quality Assurance

Dorman designs this replacement ball joint to match the original equipment function on the listed Lexus and Toyota applications. The part is engineered and rigorously tested to provide reliable service in the specified front lower suspension positions.
