[Zembonez]

These specs are for 2008 4WD but many of the specs carry over to other years. If nothing else, you'll get a good idea how tight that bolt or nut should be.

Another good source for torque specs if what you are torqueing is not listed,

For Standard thread: http://www.engineershandbook.com/Tables/torque.htm

For Metric thread: http://www.engineershandbook.com/Tables/torque1.htm

There's alot of other useful info on their site too that is worth printing out and throwing in the tool box.
