What Causes Excessive Body Sway When Driving on Slightly Uneven Roads?

[SanMadeline]

Here are detailed explanations for the causes of excessive body sway when driving on slightly uneven roads: 1. Drive shaft issues: When the vehicle is stationary, carefully observe whether the drive shaft exhibits excessive swinging. Significant swinging indicates a problem with the drive shaft. 2. Tire inspection: Thoroughly examine both front and rear tires to check for uniform tire pressure or any signs of bubbling. If such issues are found, replace the tires and perform a four-wheel alignment. Below is additional information about car tire pressure: 1. Inspection frequency: Check tire pressure at least once a month, and adjust it with each seasonal change. 2. High temperature conditions: Do not intentionally reduce tire pressure. If the tires aren't underinflated, there's no need for monthly adjustments.
