If you are experiencing any kind of shuddering problems with your FJ while accelerating get your differential fluid changed BUT make sure you also ask for a Transmission Flush so that the differential fluid in your torque converters also gets cleaned. We had the differential fluid changed a couple of times and within two weeks the shuddering was back. On the third change I asked for the fluid in the torque converters to be changed as well and was told I would need a Transmission Flush done to achieve that. We have not experienced any more shuddering with our FJ at any speed and it has been well over three months now.
