Hey everyone, as you can see I'm new to the forum and will most likely have many stupid newbie questions and my name is Hybrid like my company Hybrid Industries... not the Prius anyways, my Cherokee has always been stock until recently. I installed my first lift kit a Rancho 3.5" kit I bought from Craigslist. The kit consisted of Springs, Add a Leaf, Shocks, and Trac Bars. After installing the kit everything felt great. Felt stiff again (my old stock shocks were completely wore out) then a few days after I was driving on the freeway doing 70 when it felt like my front end was coming off. We're talking massive shaking...felt like my wheels were coming off. Shook for a few harsh seconds then went away. First thing I did was get the jeep home and double check my work. Everything looked good, nothing loose from the lift I installed. However through checking everything over I seen I am in need of a balljoint and a U joint on the front drivers side. First thought was there is the source of the shaking... but I have to wonder why did this shaking occur only after installing the new lift, not before? Maybe a stupid question... please let me know any suggestions you have.
