I've got a 2005 4Runner with the V6 engine...looking through the Maintenance Guide book, I see at 15,000 miles it requires a "Re-torque propeller shaft bolt", and at the 30,000 mile maintenance it requires the "Re-torque propeller shaft bolt" again, and also a spark plug change for the 1GR-FE engine, which I think is the V6 which I have.
Just want to enquire what the propeller shaft is? Think it has to do with the drive shaft, would that be correct? Also why such a 'fast' change of the spark plugs...I thought most plugs now last longer than 30,000 miles.
Thanks for any replies,
...Allen
