2016 Jeep Renegade Trailhawk - Front End Noise Over Bumps, Possible Strut Issue

Vehicle: 2016 Jeep Renegade Trailhawk

Hey everyone, I've got a 2016 Jeep Renegade Trailhawk with about 70,000 miles on the clock. For the past few weeks, I've been hearing a noticeable thumping or knocking sound from the front end, especially when going over small bumps, uneven pavement, or speed bumps at low speeds.

It sounds like it's coming from both sides, but maybe a bit more pronounced on the driver's side. The ride feels a bit harsher than it used to, and I'm wondering if my front struts are starting to go bad. I haven't noticed any fluid leaks, but the noise is definitely getting worse.

Could this be something else, like sway bar links or control arm bushings, or does it sound like classic strut failure? What should I be looking for if I try to inspect it myself?

ClearTheCode admin answer:

A thumping or knocking noise from the front end of your 2016 Jeep Renegade Trailhawk, especially over bumps, is a very common indicator of worn suspension components. Given the mileage, several parts could be contributing to this.

Common Causes for Front End Noise:

  1. Worn Struts/Shock Absorbers: The internal components of the struts can wear out, leading to a loss of dampening and causing a knocking sound as the suspension compresses and extends. The strut mounts (bearings and bushings) can also fail, creating noise.
  2. Sway Bar End Links: Similar to the rear, the front sway bar end links are prone to wear. The ball joints can develop play, leading to a clunking noise over bumps.
  3. Sway Bar Bushings: The bushings that secure the sway bar to the frame can degrade, allowing the bar to shift and create noise.
  4. Lower Control Arm Bushings/Ball Joints: The bushings or ball joints in the lower control arms can wear out, causing play and a thumping sound, especially when the wheel moves up and down.
  5. Tie Rod Ends: Worn inner or outer tie rod ends can also contribute to front end noise and a looser steering feel.

Troubleshooting Steps:

  1. Visual Inspection: Safely lift the front of the vehicle (using jack stands). Inspect the struts for any signs of fluid leakage, which indicates a failed seal. Check the sway bar end links and bushings for cracks, tears, or excessive play. Examine the control arm bushings and ball joints for similar wear.
  2. Shake Test (Wheel): With the wheel off the ground, grab it at 12 and 6 o'clock, then 3 and 9 o'clock, and try to rock it. Any significant play could indicate worn wheel bearings, ball joints, or tie rod ends.
  3. Pry Bar Test: Carefully use a pry bar to check for play in the sway bar links, control arm bushings, and strut mounts. Listen for any associated noises.
  4. Bounce Test: Push down firmly on the front fender. If the vehicle bounces excessively (more than 1-2 times), your struts are likely worn.

When to See a Shop:

  • If you're not comfortable performing these inspections or working under the vehicle.
  • If you can't identify the source of the noise after your checks.
  • If you find significant wear on critical components like control arm ball joints or strut mounts. While sway bar links can be a DIY, strut replacement often requires specialized spring compressors and alignment afterward. Addressing these issues promptly is important for maintaining safe handling and preventing further damage to other suspension components.
