Lots of Vibration during heavy braking
Hey All,
So my cherokee had a 3.5 inch RE lift on it when I bought it but the rear was sagging bad so I just added some Rough Country 2 inch lift shackles to even it now.
The problem is now when I brake heavily I get some crazy vibrations and grinding sounds from the rear of the vehicle. I am thinking I could have an issue with the driveshaft and angles now but I am not sure. For reference the attached picture is what my angles look like if that helps at all. Pinion is above horizonal, driveshaft is even more above horizontal and TC output is even with horizontal. Any ideas out there to fix this would be much appreciated.
Thanks,
John

I didn't and that is what I am thinking the issue is. Should I add more angle to the pinion or should I try and bring it back parallel to the ground like the t-case output?

Well, I got some 1x1 and whipped up a quick tcase drop and that solved the problem. When I have the time I will get some axle shims and get rid of the tcase drop.
