Drive shaft: Everything you need to know

The drive shaft is one of the most important components in the transmission system. In this article we will cover everything you need to know, from possible indicators of problems, what maintenance care to adopt for better operation and, finally, an estimate of how much the repair costs. Stay there!


What is the transmission axel?

The drive shaft is a part that transforms the engine’s rotation into force. This element, being the link between the engine and the wheels (passing through the differential), causes the vehicle to move or stop .

In the transmission system, the main factor that ensures proper operation is the force transmission produced by the engine to the wheels. Of all the components through which this process goes, the transmission axle is without a doubt, the most important.

There are other types of vehicles, such as motorcycles and tractors that use drive shafts. In these cases, the axles  are slightly different, since the amount of force transmitted is different from that one present in normal cars



Transmission axel symptoms

1. Can’t change the gear

Whether it’s a vehicle with an automatic gearbox or a vehicle with a manual gearbox, if you can’t make the switch, it can indicate axle problems.

2. Burning smell

If you smell any burnt odor, it could be a sign of an oil leak in the transmission system. In this situation, you should go to a  mechanic as soon as possible.

3. Noises when you are in neutral

When you’re in neutral and you hear some metallic noise, it could mean that the drive shaft is in shock with the differential. This problem can lead to damage to other parts and should be checked as soon as possible.

4. Check Engine Light

It is recommended to go for an inspection when the check light on the engine lights up on the panel.

5. Not responsive

When you accelerate with a gear engaged  and the vehicle does not move, it is likely that the problem is on the axle.



Care and maintenance

In order to avoid future problems on the transmission shaft, KROFtools advises you to carry out the appropriate checkups programmed by the manufacturer .

There are other recommendations that should be considered ::

  • Change the transmission oil within the right time :As a rule, the oil should be changed every 50,000 km or 60,000 km;
  • Tires: being the component that connected to  the transmission system, the poor condition of the tires will lead to a greater effort of this system and therefore it is essential to ensure its good condition;
  • Excessive loads: the effort of the entire vehicle will be reflected in these components . By avoiding excessive loads your shaft will certainly have less wear.


How much does it cost to repair?

A transmission shaft repair can starts at 40 euros and can reach higher values, depending on the severity of the damage to the shaft.

The price of this complete component itself starts at 130 euros, but can reach thousands.

Repairing or replacing the transmission shaft is a process that could be done at home, but it is advisable to be carried out by a professional. Being a component that is at the bottom of the vehicle is easy to access and when the car is in the lift is easier to proceed to its replacement.

  1. It was helpful when you said that you could have an oil leak if you notice a burning smell. My husband was talking about how he has been noticing a burning smell in his car for the past couple of days. I’ll pass this information along to him so that he can look into taking his car to auto services for repairs.
