The problem started when we had to replace the front axle bearings on both front wheels. When we tested the car on the road, I noticed that the speedometer reading does not indicate the exact running speed. It seems it cannot go over a 40kph reading even if my running speed is over 60kph. The tachometer seems to be working fine. Is there a problem with the speed sensor or was there a problem when we returned the speed sensor to its slot in the wheel axle?

This could be a speed sensor issue so we need to run through the testing below.

Here are a couple guides that will provide additional testing on this issue:

What I would suggest is we run through the testing but we also need to confirm the speed sensors that you installed are the correct parts.

Do you have the part numbers for the sensors you installed?

Please see the process below from the manual on how to replace the sensors and let us know what you find with this and we can go from there.

Thanks
