What is the torque specification for the Prado driveshaft bolts?
2 Answers
The torque specification for Prado driveshaft bolts is 110Nm. Relevant parameters for the Prado are: Tightening torque is 114Nm, and the nut is a 21mm hexagon. Usage method for Prado driveshaft bolts: When in use, attach the socket corresponding to the tire nut specification to the square drive of the wrench. The other end of the socket should fit over the nut to be installed or removed. Place the reaction foot of the torque multiplier on an adjacent nut, with the direction of the reaction foot opposite to the turning direction for nut installation/removal. It should be used with standard 1-inch impact sockets. Users can select different socket specifications according to nut sizes, such as 22, 27, 30, 32, 33, 35, 38, or 41mm.
When I replaced the driveshaft bolts on my Prado myself, I used a torque wrench set to around 60-80 Nm. However, this depends on the specific model—for example, my older LC120 had the driveshaft flange bolts marked at 70 Nm. If you're doing it yourself, don’t overtighten or undertighten them carelessly. If the bolts strip, the driveshaft will wobble, causing creaking noises while driving, and could even detach, leading to an accident. It’s best to check the owner’s manual or confirm with a dealership, as torque specs may vary by model year or after modifications. I learned this the hard way when I skipped checking the manual once—my driveshaft nearly failed at highway speeds, and I had to take it to a professional shop for a proper fix. Much safer and hassle-free. Also, remember to periodically check bolt tightness after installation as part of routine maintenance.
