The flange is the part the drive shaft bolts to. I have attached a couple of pic. The one pic side view....as you see, when the transmission starts to turn all the torque is right there at the connection point where the bolts connect the propeller shaft. The same on the rear part of the shaft where it connects. Anywhere it bolts, that is the torque point that is taking most of the initial twist.
The bolts/nuts can loosen over time.
Another example. Put your two hands together flat. Now twist one and keep on still.......one is the transmission (the one you are moving) and the other is the propeller shaft (the one not moving). Now put a pencil between your fingers simulating a bolt. Now twist again and don't move the other hand. The pencil twists. Same thing on your shaft......the bolts are taking that initial twist and transferring it to the stationary hand or shaft.......thus over time could loosen.
I have attached the torque value
General info on how to torque
a. Temporarily tighten the propeller shaft bolts and 2 universal joint washers.
If reusing the bolts, apply engine oil to the bolt before use.
b. Using a screwdriver or an equivalent, hold the transfer companion flange.
c. Using a socket hexagon wrench, fully tighten the propeller shaft bolts
Hope that helps.

Where in the picture is the driveshaft; is the propeller shaft the same as the driveshaft? How many bolts need to be re-torqued; is it the 6 bolts in the front of the propeller shaft and 6 in the back? Can these bolts be reached with jack stands and a floor jack?
Thank you very much for your answers.

Thanks for getting back with me.
Yes you are correct, the driveshaft is the propeller shaft.
You are correct again on the bolts. All of them front and back.
Jack stands and floor jack. If you can safely get all four tires up off the ground at a really good height, then yes, it can be done. You will want the car in neutral so you can rotate the drive shaft as you move from bolt to bolt, or nut to nut.
Make sure you are putting the torque on the nut, not the bolt.
It will be awkward under there but it can be done. Just be safe and slow. The preferred method is of course on a lift. But it can be done.
Hope that helps

Hey - while I have ya...........
Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
Although all recalls are important.........please get these checked since it deals with your Air bag and seat belts.........
