What is the correct way to meaure and align rear axle after leaf install?

I have not found the correct grouping of words during a search for this.

How do you measure so as to adjust the rear axle to the drive shaft after installing either a new leaf pack or adding additional leaf springs. I see 3 degree shims being mentioned, but how do you know if 3 degrees is too much or not enough?

Are other degree shims typically available?

Is there a "Rotating head Level" you can use to duplicate the factory angle?

This would be for a regular cab, so no carrier bearing to adjust.

 

You need to measure the angles.

Here is a link to a page that shows the magnetic degree tool in use.

There was a post on here within the last month talking about using it on our tacoma's.

Each vehicle is different and needs to be measured and then shimmed as needed. Guessing is only guessing.

The angle finder is cheap. I think I still have one from a adjustable race torque arm I adjusted on my Camaro.

lj973gm,

This was exactly the information I was seeking, thanks. I was using the wrong terms I am sure in doing my search and was only finding steering axle alignment.

I invisioned the tool in my mind, but had no idea what it would be called.
