What are the causes of abnormal noises in Haval Big Dog?

[SanThomas]

Haval Big Dog may produce abnormal noises due to the following reasons: 1. Lack of lubricating oil in the screws inside the steering wheel, which requires removing the steering wheel cover and adding lubricating oil. 2. The steering gear may have malfunctioned. Normally, if the steering wheel is turned too fully during steering, it puts a greater load on the steering gear, leading to severe wear and resulting in abnormal noises. It is recommended to inspect and replace the relevant components. 3. The coupler oil has not been replaced for a long time, which can easily cause imbalance or shaking. It is advisable to check whether replacement is necessary. 4. Insufficient tire pressure or uneven tire pressure in the left front or right front tires can cause the front of the car to deviate, leading to unbalanced wheel bearings, misaligned steering gear, and resulting in abnormal noises and deviation.

The Haval Big Dog makes strange noises when driving. I'm quite experienced, and common causes might be suspension system issues, such as damaged shock absorbers or loose suspension arm screws, which cause squeaking on bumpy roads. Loose interior parts are also common, like door panels or trunk lids not being tightly secured, causing friction noises at high speeds. The brake discs should be checked; over time, they may rust or warp, leading to noise when turning. Lack of lubrication in the steering system can cause steering noises, so timely greasing is necessary. Interior noise issues are simple to handle—you can check for gaps and pad them with foam strips to reduce noise. For suspension or mechanical problems, it's best to visit a professional shop to avoid further damage. Driving safety comes first; if you encounter strange noises, slow down and inspect the issue—don't push through.

When driving my Haval Big Dog, I've encountered rattling noises, mostly from the chassis area—issues like aging shock absorbers or suspension components that clatter on rough roads. Interior rattles are also common, such as loose seat buckles or door handles that might stop when pressed. Problems with tires or rims can cause noise, so check tire pressure and balance. A loose belt in the engine bay may squeak, and an abnormal fan rotation can generate noise. To address rattles, start with simple checks for loose parts and replace components if necessary. Don't ignore minor issues to avoid safety hazards—always listen for unusual sounds before driving.

As a car mechanic, when inspecting the Haval Big Dog for abnormal noises, the most common issues are loose suspension screws, which cause squeaking on bumpy roads. Interior clips may come loose or materials may rub together, resulting in constant squeaking. Warped brake discs or lack of lubrication can cause a humming sound during braking. Faults in the steering pump or shock absorbers may produce noises when turning. Loose underbody panels can also be noisy. Regular checks on fasteners and timely replacement of worn parts can prevent these issues. For safety, pull over and inspect immediately if any abnormal noise occurs.

The rattling noise in my Haval Big Dog mostly comes from the interior, with loose door or seat components causing squeaky friction, which is quite annoying while driving. There are signs of looseness in the suspension system, making noise over speed bumps. Issues with tires or brake pads can also generate noise. For initial handling, clean the interior gaps and test the effect by securing them with tape. For mechanical problems, seek professional assistance to ensure driving comfort.
