The most common cause of front end squeak on a Honda Accord is a failing water pump pulley bearing. Other potential causes include misaligned pulleys, slipping belts, worn wheel bearings, bad bushings, and worn ball joints or suspension parts. Proper inspection and timely maintenance can resolve the squeaking and prevent further issues.
This comprehensive guide will explore the various potential reasons for front end squeak on Honda Accord and how to diagnose and resolve them. We will cover the common causes originating from the engine timing belt area as well as other front suspension and wheel components. With some inspection and routine upkeep, you can silence the squeak and continue enjoying a quiet, smooth ride.

Timing Belt Area Issues Causing Squeaking
The most common source of front end squeaking on a Honda Accord is in the timing belt area under the metal cover. Let’s examine some specific issues that can cause noise in this region:
Failing Water Pump Pulley Bearing
The water pump pulley bearing going bad is the number one culprit for squeaking heard near the timing belt cover. As the pulley bearing starts to fail, it will begin to make grinding and squealing noises. Eventually, it will seize up entirely, leading to overheating issues as the water pump stops working.
Replacing the water pump and pulley promptly can restore quiet operation. The bearing tends to fail around 100k miles on many Accords.
If one of the pulleys aligned with the timing belt has become misaligned, it can introduce wobbling and noise. This typically happens if the timing belt was replaced incorrectly or an adjustable pulley was not properly realigned.
Carefully inspecting the alignment and re-adjusting the pulleys can stop the squeaking. The tensioner pulley is often the culprit.
Slipping Drive Belts
Loose, worn, or damaged drive belts, like the serpentine belt, can start to slip on their pulleys. This slipping can make loud squeaking or chirping noises.
Replacing old belts and properly tensioning new ones will resolve it. Check for belt wear, cracking, or missing teeth.
Excessive Timing Belt Tension
Too much tension on the timing belt can lead to noisy operation and premature wear. A replacement belt that was stretched too tight or a tensioner adjusted too far can cause this issue.
Relieving some of the tension and realigning components is needed to stop the noise.
Other Front End Noises Checklist
Besides the timing belt area, front end squeaking on a Honda Accord can also emanate from other components. Here are some other key areas to inspect:
Wheel Bearings and Hubs
Worn out wheel hub and wheel bearing assemblies are a common reason for front end squeaking and growling noises while cornering or braking.
Raise the front of the car and check for play by wiggling the wheels. Uneven tire wear can also indicate bad bearings. Replacements will be needed if bearings are shot.
Dry, cracked, or worn suspension bushings can squeak when going over bumps and turning. Push down on the front end and listen for noise when checking bushings on the control arms, sway bars, struts etc. Lubricating or replacing bushings resolves it.
Ball joints that are dried out and worn will click and squeak when steering and hitting bumps. High mileage Accords often need replacement ball joints. Check for torn boots and sloppy play indicating wear.
Joints, links and other suspension components can begin to squeak from lack of lubrication. Greese and lubricate parts like tie rods and joints to stop metal-on-metal squeaking. It may require bushing or joint replacement.
Quick Diagnostic Checks
Here are some quick checks that can help pinpoint the cause of squeaking from the front end of your Honda Accord:
- Listen under the hood with the engine on to isolate noise from the timing belt area.
- Check and wiggle each front wheel with the car lifted to check for play, indicating bad bearings.
- Inspect serpentine belts for visible wear and re-tension if loose.
- Push down on the front suspension components while turning to check for play and noises.
- Check ball joint boots and tie rod boots for rips indicating the need for lubrication or replacement.
- Turn wheels fully left and right to listen for clicking ball joints or tie rods.
Regular preventative maintenance is key to avoiding many conditions that can contribute to front end squeaking on a Honda Accord.
Here are some important proactive checks and services:
- Replace the timing belt, water pump, pulleys, and drive belts at suggested intervals
- Lubricate suspension and steering components
- Check wheel bearings for play and noise
- Inspect tie rod ends, ball joints, and wheel bearings for wear
- Replace worn components before complete failure
Keeping up with these basic front end services will minimize the odds of noise developing. Address any new squeaks, growls, or whines promptly before damage worsens.
Why Is The Front Of My Car Squeaking When I Hit A Bump?
The most common reason for the front end squeaking over bumps is worn-out suspension bushings. Bushings provide cushioning between metal suspension parts. When they get old, the rubber breaks down, and they lose the ability to dampen noise. This allows metal parts like control arms and struts to knock together, creating a squeak or clunk when going over bumps.
Replacing cracked and degraded bushings with new ones will typically stop the noise. Ball joints, sway bar links, and tie rods are other front end parts that can also cause squeaking if they are dry and worn.
What Causes Squeaking Noise From the Front Wheel When Driving Slow?
A squeaking noise that seems to come from the front wheel area while driving slowly can often be traced back to worn wheel bearings. Wheel bearings allow the wheel hub and rotor to spin freely. Over time, with wear, the bearings develop play and can start to grind and squeak, especially at low speeds when making turns.
Damaged wheel bearings will need to be replaced in pairs on the affected wheel to restore quiet operation. Bad brake pads with worn out friction material can also chirp and squeak from the wheel area, so inspect the brake components as well.
How Do I Stop My Front Suspension From Squeaking?
To stop suspension squeaks, first inspect components like control arms, struts, sway bar links, and tie rods for any degraded rubber bushings and replace them as needed. Ball joints should also be checked for wear and re-greased. Another critical step is to lubricate all the suspension joints and bushings, as dirt and lack of grease are often the root causes of noise.
Spray down joints and bushings with a silicone lubricant. The inner tie rod ends are particularly prone to squeaking when dry. Opening up stuck grease fittings and pumping in new grease can help silence noises.
Why Is My Front End Making A Squeaking Noise?
There are a few likely reasons a general squeaking is coming from the front end when going over bumps or turning. The most common causes are worn ball joints, lack of lubrication in the suspension components, and degraded, hardened rubber on suspension bushings.
Start by checking for any cracked bushings and missing grease boot covers on the ball joints, tie rods, and sway bar links. Replace any damaged parts. Then, thoroughly lubricate all the joints and bushings on the control arms, struts, links, and steering components. Add grease via zerk fittings if possible. This should quiet most front end squeaking.
