Shimming rear axle?

[stallion85]

Right now I have a 2 1/2" lift with springs on all four corners. I had the transfer case dropped but I would rather get an angled shim for the rear. I have two questions:

1. The springs already came with a shim in them ( Don't know what degree) can I put another one on with the existing one?

2. How do I found out which degree of shim I need?

Just want to get rid of the vibes without having the xfer case dropped

Any help would be appreciated, I am all

i dont see how adding another shim could hurt. use and angle finder(theyre cheap) to find the angles and the angle you need. the pinion adn transfer case output should within 2 degrees of each other to eliminate vibes iirc

Have you tried to run it without dropping the t-case to see if you even get vibrations??
The angle at the output of the t-case should be parallel with the input at the axle.

I have had the transfer case dropped and I did not get vibes. I prefer it to not be dropped due to the fact I need all the ground clearance I can get with only 35's and a 2 1/2" lift. Do you think a driveline shop would charge me to help me find the correct shim angle??

What I am saying is have you tried to drive it without dropping the t-case??
Finding the angles is really easy if you need some help feel free to PM me

Oh yea, I am driving it right now without it dropped. I raised it after I banged the hell out of it a few times. That's when I started getting vibes

angle finders are cheap and easy to use. the output of the tcase and pinion need to be at the same angle. with some VERY basic math(adding subtracting) you could figure out what degree shim you need

so you are getting vibes without it dropped correct??
Then you need to go get you a angle finder, they can be found at home depot or lowes for about $5-$10.

Then check and see how far off your angles are from being parallel to each other

Cool, Thanks Yes that is correct and yes I will get an angle finder
