Just got done with the 3.5" re lift, used 3* shims. Getting some good vibes up to 30-35mph. And when I decel from about 35-10mph feels almost like a grinding sound/feeling, not harsh but lightly. I'll be throwing the 31's on and doing my alighnment tomorrow.
Do I still have a driveline angle issue or maybe a u joint issue?
As far as the grinding sound, I guess it could be from the fact that my tires are slightly toed inward at the moment, will see if problem persists after alighnment. Just wanted input on these issues.
Also I searched, but the search feature really is a pain to find anything.
thanks guys

 

You probably need a sye or a transfer case drop. I say this because mine did this until i did a transfer case drop. I have since removed the drop and installed a hack and tap sye and the problem has not returned.
