Causes of Driving Cars Howling When Accelerating

In the process of using a car, when accelerating, the undercarriage may vibrate and emit an annoying howl. The cause of this problem may be that the connection between parts in the shaft mechanism is worn, damaged, or loosely connected. This problem is usually caused by the following reasons:

• The transmission shaft of the Rzepp post joint is bent or loose.
• Joints are worn out.
• The transmission gear or bearings have been damaged or have excessive wear.
• The drive gear and the passive gear of the main transmission are too open.
• Abrasion of planetary gears, semi-axle gears of differentials.

How to identify the problem:

• In the process of driving, the car is shaken, the faster you go, the clearer the shaking and rattling and howling sounds.

How to Fix Running Cars Howling When Accelerating

Depending on the cause, there is a reasonable examination and diagnosis of "disease".

Check and adjust the main drive and differential

When the vehicle is often overloaded or has an accident, the main transmission and the differential are easy to wear, broken gear teeth, and damaged bearings. In normal working conditions, this phenomenon is very unlikely to happen.

• Check the clearance of the planetary gears

The planetary gears are structured and back-aligned against the differential box through the pads. The required distance is 0.1 – 0.3mm. If the gap is too wide, it is necessary to replace the mattress to reduce the gap gap, this is the cause of loose joints, fast running causes a sound.

• Check and adjust the bearing of the drive gear

If the bearing is too tight, the torque will be greater than the rated value. At this time, the gasket 5 must be removed to separate the two inner rings of the bearing.

If the torque is less than rated, reduce the gasket 5, tighten the nut.

• Check drive gear and drive gear looseness

The threaded nut or the cushion structure can be adjusted.

• Check the clearance of the ring gear bearings

Bearings of ring gears require no play or very small play. Therefore, when the car shakes or makes noise, you need to check its rotation on the drive. If it spins at a fast and strong pace without making any noise, it's fine. If there is a squealing sound, add additional buffer evenly and tighten the nut until it meets the requirements.

• Check and adjust two gear contact traces

The drive gear and the ring gear must be adjusted to the correct amount to have a good engagement. If the contact between these two gears is moved to the correct center of the shaft, the transmission is smooth and does not cause wear.

Check the joints of the Rzeppa posts for wear

• If it is found that the joints of the Rzeppa posts are not worn but loose, remove the inspection parts and reassemble.
• If it is found that the spherical cavity, core, positioning ring or ball has been worn or cracked, replace it with a new one. At the same time, check the connection between the joints and the rubber dust shield to limit dirt, tear, and puncture.
