How many kilometers should the Corolla engine mounts be replaced?

The Corolla engine mounts should generally be replaced every 150,000 kilometers, or once after the vehicle has been driven for six years. Of course, they can be replaced earlier if there are other circumstances. Full name of engine mounts: Car engine mounts are the mounts of the car engine, with various full names such as engine mount rubber, engine buffer rubber, engine fixing rubber, etc. Function of engine mounts: When the engine is working, it generates certain vibrations. The engine mount rubber contains rubber components that can eliminate the resonance produced during engine operation. Some engine mount rubbers also have hydraulic oil pressure relief functions, all with the same main purpose. If the engine mount rubber is damaged, the vibrations from the engine will cause the entire body to be in a state of vibration. There are usually three engine mount rubbers, fixed on the vehicle frame. If one is damaged and not replaced in time, it disrupts the balance and can cause the other two to deteriorate faster.
My Corolla started to shake a bit when it reached nearly 100,000 kilometers. Later, an inspection revealed that the engine mounts were severely worn out. The mechanic said these parts typically need replacement every 100,000 to 150,000 kilometers, especially if you frequently drive on bumpy roads or accelerate aggressively, as they wear out faster. From my own experience, paying attention to engine vibrations and unusual noises while driving can help detect issues early—don’t push it until it fails, as this could damage the transmission or chassis, leading to extra costs. Having the technician check them during regular maintenance makes things much easier. For a Corolla, this isn’t too troublesome, and using genuine parts can extend their lifespan.
As an average car owner, I think the replacement interval for Corolla's engine mounts depends on individual driving habits. My car was driven on city roads until 130,000 kilometers before needing replacement, and the mechanic said the average recommendation is every 100,000 to 150,000 kilometers. The key is to monitor the vehicle's condition closely. For example, noticeable engine vibrations at idle or a rattling sound upon startup should raise red flags. Don't rely solely on mileage, as poor road conditions or frequent heavy loads may cause premature failure. I recommend getting a professional diagnosis at a 4S shop to avoid misjudging the issue and wasting money.
