All All-Wheel-Drive Problems, Operation & Description
This article majorly covers AWD systems on the whole, so its application can accommodate that comprehensive set of models and years. AWD is an evolutionary step forward from 4WD, though they are often mistaken for a similar system. Have you ever wondered how your all-wheel drive or 4-wheel drive vehicle can shift weight so that your luxury tyres can gain traction? Here is the breakdown:
4WD Systems: These the systems that date back for over 70 years and were developed to improve traction in slippery conditions. Engine power is directly delivered to all four wheels via a mechanical component called a transfer case. The case is behind the transmission and delivers constant power to both mechanical via axles action.
AWD Systems: Operate in the same fashion, and while there are various AWD types, they all function similarly. Power is sent at a constant rate to the rear (RWD) or frond (FWD) axles. When the all-wheel-drive system determines that improved traction is needed, the other axle is completely engaged. The active axle permits the wheel to be released and freed when the circumstances are right. The major advantage for modern drivers is the fuel saving that comes from all-wheel-drive systems.
Always keep in mind that both systems are them to improve your ability to make forward progress on the wheel when conditions are at their worst. But how do you understand how the system is working? In the next section, we are going to discuss some common signs that indicate your system is operating as designed. And in some conditions, not!
All-Wheel-Drive Problems: Dirty & Down
Traction is achieved through AWD, 4WD, and other systems like hill start assist, driver skill, drive-more selection, traction control, and simply put tires. You can have the most impressive AWD system in the world, but if you are in mud and your tyre bald, you are going to be there for a while.
Moreover, there is more to achieve in the battle for traction than having 4WD or AWD. Let’s take a look at some symptoms, questions and solutions commonly associated with All-Wheel-Drive Problems.
What Are the Bad Transfer Case Problems?
The transfer case is an impressive piece of equipment that operates a complex matrix of chains, gears, actuators, and shafts. If you have got All-Wheel-Drive Problems, this is likely the place to look for. If you think you have got a wrong transfer case (or “t-box” or “t-case” in the mechanic speak), you will know. Here are some common signs that may arise when you have a bad transfer case:
- You have a transfer case over temperature warning on the dash.
- You may hear a grinding when traveling at highway speeds.
- You might experience blinking lights in the vehicle drive selector area
- You might hear a bang bang bang sensation under hard acceleration.
- Last but not least, you are getting whenever you know you shouldn’t.
How Can I Determine Whether My Gearbox or Transfer Case Problems?
Excellent query! Despite having distinct purposes, these parts cooperate to keep your car traveling smoothly from point A to point B. Using a factory scan tool is the most precise method of problem diagnosis. Modern Volvo cars have onboard computers that track everything, so we can identify any problems with them without having to make assumptions.
To help you narrow things down, you can attempt the following do-it-yourself tests:
- Put your foot on the brake, start your automobile, and choose between drive and reverse. Did the vehicle feel engaged? If not, you probably have a gearbox issue.
- Look for a clear road if your car is capable of moving. Try rapidly slowing down and then picking up speed. Do you have a sense of being trapped in quicksand? That might point to a significant gearbox problem.
- Try doing a complete circuit at low speeds, turning left and then right, if the car seems to be driving smoothly. Is there an odd grinding sound you can hear? That is a clear sign of a problem with the transfer case.
- When driving down a highway, keep an ear out for a high-pitched wail. Another indication that your transfer case might be the problem is if the pitch changes as you release the gas.

What can I do if my All-Wheel Drive is not working properly?
There are numerous instances where a minimal repair might get you going again and again. Actuators, sensors, and solenoids can be replaced. If that is the case, your warranty coverage may cover all the repairs. If it is not one of these simple solutions, then you are likely looking to replace and rebuild your transfer case.
What are the disadvantages of All-Wheel Drive?
4WD enthusiasts will tell you that All-Wheel-Drive is the less trusted of the two systems. That argument rests on the fact that true 4WD is usually mechanical and permanent- that’s why more reliable. AWD tyres create fuel economy by relieving engine load from one of the live axles. All-Wheel-Drive is a large support component to do this.
