What Causes the Heavy Steering Wheel in Buick Excelle?
1 Answers
Here are the reasons for the heavy steering wheel in Buick Excelle: 1. Insufficient power steering fluid/oil: Power steering fluid needs regular replacement. Check for leaks as insufficient fluid causes heavy steering. 2. Low tire pressure: Underinflated tires increase contact area with road surface, raising friction and making steering harder. 3. Toe angle: Incorrect wheel toe alignment affects steering self-centering capability and straight-line stability. 4. Steering gear or power steering pump failure: Malfunctions in these critical components lead to steering difficulty. 5. Overly tight bearing fit: Excessive tightness in steering system's rolling/sliding bearings causes poor lubrication and sticking.
