My car is L300 FB model '97. I am experiencing body vibration or kumakadyot ng bahagya ang body ng sasakyan habang tinatapakan ang gas pedal, the speed is approx. around 50kph. The two propeller crossjoints were replaced. The two transmission mounts were replaced because they are already worn out. But the problem is still there. Kindly give me some advice. Thanks.
You might want to replace the carrier of the prop shaft too. And how the cross joints were installed. Slighlty off and the prop shaft will be rotating out of round. This will be likely the cause particularly if the vibration goes away after you go beyond a certain speed. This is just one probable cause. Can't really tell without actaully checking on the vehicle.
