Recently I have driven my parents 2014 Crv 2.4l 4wd for almost one month and realized it occasionally feels vibrates/shaky when I slowly accelerate and it happens between 40 to 60km and 1500 to 2000rpm. When you accelerate hard, it doesn't have any vibration. Already changed all engine oil, transmission oil, rear differential oil and spark plug but still remain the same. I have sent to workshop and they couldn't figure the problem. I sent Honda SC and they just checked thru the device and no problem shown (they didn't jack up the car to check details).
Any owners have faced the similar problem? And hope to get some feedback. Thanks.

Could it be? It happens quite constant when slow accelerate as mentioned speed. After 60km/h, there is no more vibration.

My mechanic suspect is the LSD problem. This weekend i will ask him to take a look on engine mounting. It is kinda annoying when it only occurs on certain speed. Are yours also occurred same as my mentioned speed? It only happens when i accelerate slowly. When it vibrates and i release my foot off, it stops vibrating. I'm kinda worry if it is gearbox problem.

Mounting issue will cause shaky/vibration at certain speed? Like mine occurs during 40 to 50km / 1500 to 2000rpm when accelerate slowly. After 50km, it has no more vibration.

Already checked tyres and done balancing, but still happens.

My mechanic said both sides drive shaft is ok. Just found out the middle long shaft is worn out, the movement is very stiff no longer smooth. Will source and change the long shaft then continue to observe. I only hope that is not gearbox problem.

I think he refers to propeller shaft which he said middle shaft which connects front and rear. He said the rotation is no longer smooth.

Here is the photo. It should be propeller shaft.
My mechanic suspects this is the problem.
He sourced a used shaft rm2.5k and condition also not that good so he rejected it.
Not sure what is the market price for this shaft.
