Control Arms Buying Guide: Frequently Asked Questions
What are Control Arms?
All-important parts of a vehicle's front suspension. Some models have four of them -- two lower, two upper -- and they can also be called "A arms."
They connect the frame or body to the wheel assembly or steering knuckle and attach at the outer ends via ball joints. Sometimes the joints are permanent, sometimes they're simply pressed or bolted in. The latter enables replacing the joint if you ever must. Rubber bushings allow the arms to swing vertically when the vehicles front wheels and tires go over road hazards like bumps and potholes.
What Do Control Arms Do?
It's straightforward: they ensure dependable steering by keeping the front wheels on the road, the way they should be.
What are the Signs of Control Arms Going Bad?
They range from bending, general damage, and pops or clunks during driving to loss of control and brake drift across uneven terrain. More specifically, these symptoms indicate degraded ball joints or torn control arm bushings. Both can result in the complete separation of the front wheels from the rest of the suspension.
If you see such signs, you should inspect your Lexus on a hoist. Do this annually, at least once. If you need to replace any of the vehicle's control arms, be sure you buy genuine.
