(pinion angle) How to change my trans angle?
#22
The way i used it for years pinion angle 5 degrees facing up, trans shaft facing 6 degrees down
Or now with the shims wish are secured with the bolt trough the middle hole and the u joints holding it on the sides so it cant move with the pinion angle 2.5 facing down and trans shaft 6 degrees facing down?

The amount of pinion angle you put in will be more in line with what your doing. Track vehicles with leaf springs want more pinion angle than a truck you ride around on the street. Keep that in mind.

So in your opinion wish setup is better:

My pinion angle is -2 but you definitely want it to be negative not positive. For track purposes, you have to assume that under power the pinion is going to rotate upwards. This can negatively impact your pinion angle if not accounted for. The goal should be to have an angle close to zero but not zero under max power to keep the ujoint happy and to transmit max power to the rear end.

You haven't actually given me your pinion angle. What is the angle of your driveshaft?

-Im taking both picture from the passenger side
-the left side of the driveshaft (the side that connects to the rear end) is pointing down to the floor 2 degrees

My jeep trans is pointed down but my rear angle is up....the driveline angle is the key to no vibration
In racing you have to take into account axle wrap and thats where ppl refer to having pinion neg

This is becoming a mess.
As George has said. Get the transmission mount to as close to the stock angle as possible.
Since you have a lowered truck, as you have experienced the rear angle will be the one that will be off.
If both are off, all you can do is be patient and get the transmission mount to where it can be functional and then go the rear and work there.
Like was already said about using your angle finder, pick a way and do the best you can and ask questions if your confused to that provider of instruction. Dont ask anyone else, your just making a mess if you do.
Good luck to you.
