I just put a CST 7" lift with total chaos upper uniball arms, radflow coilovers with external resi, deaver pack with 1.5" block to level it and rancho shocks to finish the rear on my 07 2wd titan. I have 2 issues. Number 1, I am getting a loud thud when, what feels like, the suspension rebounds. Any idea what that is and how to fix it? And second, I have a pretty big vibration from about 5mph to 45-50mph. Any ideas there? Any help is great!
