Hi
I have a 1.75" spacer lift on my 2003 Rubicon and am experiencing slight vibrations at highway speeds and under hard acceleration. I have owned the jeep for 2 years and have always had them and just thought it was a jeep thing but have started to think otherwise. It is most noticeable on the highway doing abut 65 - 70mph. Its a slight pulsing vibration I can feel in the seat and center console. It seems to have gotten slightly worse since I replaced my worn out shocks with new Quadratec nitro 8.0s that ride awful BTW and will be replaced with Ranchos. I am skeptical it is drive line related however because I have read that even a 2" lift on a Rubicon should not cause any vibrations. I have checked the u joints and output yokes for play and everything's solid. I did however notice that on the transfer case side yoke there are rub marks that I believe is due to over flexing and binding while off roading. One other thing id like to note is whenever I've droped the transfer case skid I have had to spread the frame apart one way or another to get the bolt holes to lineup. I plan on doing a DPG OME 2" kit with adjustable control arms and a CV driveshaft in the future but would like to keep the spacer lift on for now. I do a lot of miles in the jeep and dont want to blow out a u joint let alone damage the rear axle/transfer case.
Any help would be appreciated
Thanks
