If the Transmission Fluid is Low

We know that the low transmission fluid is one of the causes behind the clunking sound of your Chevy Silverado. If you are also facing this problem then you may follow the following steps to fix it now.

Step 1: Check the Transmission Fluid

At the beginning of the solution, you have to check the fluid level of your transmission gearbox. There is a traditional method of checking the fluid level. You may follow that method. That is the best way to measure how much fluid you have on this part of your vehicle.

Step 2: Check Fluid Thickness

Besides checking the fluid level, you also have to test the thickness of the fluid. As we know after a certain period of time, the fluid becomes thick and color changes. That means the fluid is outdated. It’s time to change it as soon as possible.

Step 3: Refill The Fluid

After checking the fluid level and thickness you will find the level is lower than expectations. In that case, you have to drain all the transmission fluids. You also have to remove the transmission fluid filter. Then you have to enter new fluid in the tank. Keep the recommended fluid level. This will help the transmission system work smoothly and there will be no clunking sound when you are accelerating your truck.

If Front Axle Bearing Has Problem

Another possible cause of clunking sound when accelerating is the front axle bearing problem. Most of the time the front wheel axle creates such sound. Let’s see how to fix this.

Step 1: Identify Source of Sound

First of all, you have to identify from which bearing the sound is coming. If it is from the left wheel then we have to work on that. But if it is on the right wheel then we will have to work on the right one. So identifying the source of sound is very important.

Step 2: Remove the Wheel and Bearing

When the sound source identification is done, we have to remove the wheel from the axle. If the wheel is removed, the bearing will appear in front of you. You have to use a puller and then bring out the bearing from the inside part of the axle.

Step 3: Replace the Old Bearing

When the bearing removal process is done, you have to bring a new bearing and replace the old one. This is the main part of this process.

Step 4: Re-Setup Everything

When all the steps are done, you have to fix the wheel in its position. Always try to tighten the ring bolt as much as possible. The loose wheel may also create such a sound.
