Why does the CRV shake at 40 mph?
2 Answers
When the lock-up clutch in Honda's torque converter slips during operation, it can cause shaking or continuous vibration, leading to torque converter lock-up shudder. The specific reasons for Honda CRV shaking at 40 mph are as follows: 1. Worn friction plates: The lock-up friction plates inside the original torque converter have limited lifespan and poor wear resistance. 2. Improper transmission fluid maintenance: The correct transmission fluid change interval is every 2 years or 50,000 kilometers using genuine transmission fluid. 3. Using incorrect fluid: When changing transmission fluid, if inferior or counterfeit transmission fluid is used instead of genuine fluid, it can cause this issue.
I also experienced body shaking at around 40 mph when driving my CR-V, feeling like the wheels were slipping on uneven roads, which really affected the driving experience. Later, I figured out several common causes: improper tire dynamic balancing is the most common issue, as uneven tire wear or running over debris can cause wobbling; additionally, warped brake rotors or caliper problems can also cause shaking at specific speed ranges; aging suspension components like worn shock absorbers are also worth checking. If you encounter this issue, don’t rush to drive long distances—pull over and check tire pressure and tread consistency. If the problem persists, take it to a professional shop immediately. During regular maintenance, have the technician test wheel hub balance to prevent minor issues from turning into costly repairs, which can be both expensive and frustrating.
