Shop Finished Building My New 4" Aluminum Driveshaft This Morning

NO, it's a new takeoff with 1138 miles on it, why you need one?

^It does matter actually. There's more axle wrap (the pinion pitching up on acceleration) with such tall blocks vs. leaf packs, because the blocks act like a lever. That then causes vibrations on takeoff.

There are a few traction bars offered for our trucks that'll eliminate axle wrap completely, but the good ones require welding: https://www.tacomaworld.com/threads/traction-bars-for-2012-prerunner.264750/

 

It doesn't matter when it comes to the Tacoma lurch when you come to a stop.

Even with the Alcans, GoPro video shows the axel wrap, but it unloads with the solid driveshaft. It doesn't with the 2 piece. There is A LOT of data on all of this already especially in the 2nd gen section.

I'll draw some diagrams for the short bus riders

 

No issues with vibrations. But you are comparing apples to oranges. A steel Tom Woods vs a custom made, all thick walled 4" aluminum. I have 4.56 gears, so once I hit about 85-90 it shifts down to 5th gear. at about 100 it drops down to 4th and gear and the RPMs start to get up there.

 

You shouldn't be driving a 6" lifted truck at 100mph and need to get a new phone.

 

Driveshaft speed is always a constant multiple of wheel speed. It doesn't change with transmission gearing or rpms.

Steel Tom Woods driveshaft is also thick walled. However, yours being larger diameter probably helps.
