propeller shaft bolt

In the scheduled maintenance log it says to re-torque propeller shaft bolt. I have a 2009 reg cab tacoma 4 cyl 2 wheel drive manual, and @ the dealer and a mechanic said I didnt need to worry about this, but why is it listed? When stopping, after a momentary delay, I feel a slight push like if I had a load it just shifted forward. The mechanic said this was also normal, just the springs rocking. But with no load I wonder if this propeller shaft bolt has something to do with it. Any ideas if this really is normal?

 

sounds like axle wrap...a aal will help

 

I tried to torque those with a crowfoot adapter on my torque wrench. Started to round off the nut...gave up. I'm going to need a box-end adapter.

 

Just get a couple 14mm box wrenchs and get them good-n-tight. Unless you're a teensy tiny human being, you'll torque past the 65# torque spec of the driveshaft bolts getting them to "tight as I can get 'em".

Just make sure they're good and snug and relax.

 

Great idea! Don't forget adding an extention to the torque wrench changes the torque. Here's a link to help out...

How many propeller shaft bolts on the 4WD...8?

 

X2 ?. I would like to be sure I have done them all when I'll do it.

 

If you ever need a crows foot for tightening anything, use a Snap On Flank Drive. It will shear off the bolt before the tip spreads. I have tried this with craftsman and matco wrenches.

14mm crows-foot, if you are really serious about using the torque wrench:

Yes, its 8. Just did this a few weeks ago...

 

If your truck is two wheel drive, you won't have a propeller shaft bolt. There's probably a note on your schedule somewhere. My truck has the same bump or thump. Nothing to worry about.

 

Just for reference a crow foot and will effect the torque reading as it adds to the length of the wrench:

The complication with a crowsfoot on a torque wrench is that the scale is calibrated to its center of rotation (where you would normally put a socket), but the lever arm (the perpendicular distance from the center of the bolt to the hand grip on the wrench) will be longer or shorter than that depending on how you apply the crowsfoot. To make it just a bit more complicated, the more force you put on a torque wrench, the more it twists--this doesn't effect the length of the lever arm in normal application where a socket is centered on the rotation point, but when using a crowsfoot, the length of the lever arm could actually increase or decrease as the wrench starts twisting. In the example shown below, if the wrench reads 100 foot-pounds torque, the actual torque with the crows foot is 100 x 20/18 = 111 foot-pounds.

 

My 2wd has prop shaft bolts. I can't really imagine how it would be held on otherwise, unless it had slip joints at both ends.

 

Yes we all have bolts. No that's not your issue. You probably don't even need to tighten.
