How to Deal with Rear Axle Noise in Wuling Zhiguang?
2 Answers
The meshing clearance between the half-shaft gear keyway and the half-shaft spline teeth is too large. Adjust the clearance or replace the relevant components; Insufficient or poor lubrication can also cause similar phenomena. Replace the engine oil or adjust the clearance; When the half-shaft or half-shaft sleeve is bent and they rub against each other, noise will occur while driving. It is necessary to replace the relevant components or go to a repair shop for maintenance.
As a veteran driver with over a decade of experience behind the wheel of a Wuling Sunshine, I've encountered rear axle noise issues multiple times. The main causes usually involve worn differential gears or damaged bearings, with the noise becoming particularly noticeable on bumpy roads. Here's my diagnostic approach: if the noise diminishes during acceleration, it's likely a differential problem; if it gets louder when decelerating, the bearings are probably shot; constant squeaking often indicates insufficient lubrication causing friction. Don't delay - get it to a repair shop immediately. Avoid DIY disassembly as you might damage the drive shaft. After replacing gears or bearings, the noise significantly reduces. Never neglect maintenance - check rear axle lubricant levels every 20,000 km or so, topping up when low to prevent premature wear. If noise occurs while driving, reduce speed and pull over immediately to avoid loss of control risks.
