The Audi Q5 was brought in for inspection and makes a clicking sound when turning

When an Audi Q5 enters the store, the owner describes a problem where the chassis makes a very noticeable clicking sound when turning while driving, but it rarely occurs when driving in a straight line, only during noticeable acceleration and deceleration.

For such a problem, the master must conduct a test drive to determine. First, let's take a look at the dashboard. The total mileage has exceeded 140000 kilometers, and the car was produced in 2016 with four-wheel drive.

After the test drive, the master can basically determine that the problem is with the right front half shaft, which is likely to be the problem with the outer ball cage of the right front half shaft, but further inspection is needed.

Then the master lifted the car up and we took a look at the condition of this Audi Q5 after 9 years and 140000 kilometers of driving. Let's look from the back to the front, as shown in the figure below. The rear suspension is a trapezoidal linkage independent suspension.

The sturdy rear suspension is made of steel material, while the rest of the components are mostly made of aluminum alloy material. After inspection by the technician, it was confirmed that there are no problems with the rear suspension components, and they are mostly original car parts.

Looking at the rear differential shown in the picture, there is a separate iron block at the rear that buffers resonance and is fixed to the rear subframe. There is a plastic small protective plate at the bottom of the subframe to prevent the sound of stones splashing.

Let's take a look at the front suspension, which belongs to the five link independent suspension. The lower two connecting rods are made of aluminum alloy material, and the steering knuckle and upper fork arm are both made of aluminum alloy material.

We noticed a problem with the right front suspension, where the aluminum alloy steering knuckle was covered in a layer of black grease. The outer ball cage cover was loose and loose, and the technician inquired and learned that the ball cage cover was replaced later. The old ball cage cover has been leaking oil.

Compared to the suspension on the left, there is no oil pollution at all. The outer ball cage cover of the half axle here is normal and still the original car ball cage cover.

Subsequently, the master checked the outer ball cage of the left half axle and asked another master to get on the car and start the vehicle, causing the wheels to turn. He checked the outer ball cage of the right half axle again and confirmed that the abnormal noise was coming from the position of the outer ball cage. The problem was confirmed. The master said that the repair method is to replace the damaged half shaft outer ball cage, usually by replacing this half shaft.
