Oh man thats rough! My poly torque axis mount lasted a trip to the store. The car actually felt better with no mount in the front than it did with the poly mount. It was bad.

 

The mounts are different between 2wd and 4wd on GMT800 trucks. 2wd had one stud and 4wd has two.

 

i just lowered my truck and its to low i like the height of your truck and wanted to know can you tell me the distance from the center hub to fender front and rear on yours?

 

15.0" all four corners

 

awesome thanks for quick response!

 

Here are my driveline angles on the truck. I'm trying to determine the operating angles of the u joints. Am I correct that I add both angles together to get the operating angles in the drawing below?



So I would have 4.60° rear operating angle and 8.35° front?

Rear Diff:


Rear U-Joint


Front U-Joint


Tranny

 

Oh No.... Angles......
Get ready for every possible answer in the world......

Based on the direction the gauge says it is reading for each angle, you are correct.

An easy way to take the human error out of it is to put it on the diff, press the zero button (it will now read 0°), now put it on the driveshaft and it will find the difference (operating angle) between the two.

 

Man, that's brilliant, I can't believe I didn't think of that. I just zeroed it out on a level to make sure it was reading accurately and that never crossed my mind...

For now I'm going to shim the trans mount and then remeasure until I get them equal or within 1°

 

i think up to 3* difference is acceptable, last truck i had a drive line vibration had to shim the diff and trans to get rid of it and i want to say i got it to 2* difference and got rid of it
