What causes control arm damage?
What Causes a Control Arm to Break? Over time, bushings and ball joints can wear out due to friction, heat, and stress from various loads and movement. Harsh conditions, like driving on rough terrain, can accelerate the wear and tear of control arm bushings and ball joints.
Why do my control arms keep breaking?
A lower control arm bushing could break from being too worn out. It could also have been damaged accidentally by a mechanic who was working on something else. If a control arm is excessively worn, damaged or bent, the vehicle is NOT SAFE to drive.
Why does a damaged control arm cause unstable braking?
A sudden improvement in braking efficiency can, as strange as it may seem, be attributed to a damaged control arm bushing. This is because the forward and backward oscillation of the control arm is not achieved during braking due to bushing wear. However, this effect will not be constant, making braking unstable.
What happens when rubber is worn out on control arm?
In case of extreme damage, when the rubber bushing is completely worn out, the metal sleeves of the control arm will begun to rattle, resulting in an unpleasant ‘clunking’ noise from the front end, especially while turning or reversing. Moreover, the wheel with a damaged bushing will begin to wobble while driving.
Why are the ball joints on my control arm worn out?
They are equipped with bushings and ball joints that allow it to flex and move according to road conditions and steering input from the driver. Over time, the bushings or ball joints on the control arm can wear out and cause all sorts of problems.
When to replace a bad lower control arm?
Replace the bad control arm to stop them. If your lower control arm is worn out or loose, you’ll notice a lot of strange clunking noises coming from the frame area.

When to use upper control arms on Jeep Wrangler?
If your car is lifted above 3” then it’s ideal to have an upper control arm that will keep your pinion angle in place, preventing axle wrap from occurring. An aggressive lift kit could interfere with your Wrangler’s drivetrain angles, causing damage.
Why are the brakes on my Jeep locked up?
Overly tight drum brakes in the old days was caused by backing up out of the driveway/parking spot frequently and aways the same direction. Backing up and braking could cause the self adjuster to tighten, and going the same direction (backing up to the left for example) would only apply wear to the opposite side eventually causing tightness.
Do you need control arms for Jeep lift kit?
Here are the biggest cons of keeping your stock control arm system with an entry level lift kit: Aftermarket control arms are a good way to augment your lift system and ensure your Jeep is running smoothly. Choose from short, adjustable control arms for lifts below 5” and longer arms for higher lift kits.
How does axle wrap work on a Jeep Wrangler?
Decreasing your caster angle will result in tighter steering, but restricted wheel self-centering. A positive caster angle will improve stability at high speeds and improve cornering. “Axle wrap” is defined as a change in your pinion angle. Axle wrap occurs when your axle wraps itself around the springs.
