So I recently got my Jeep the 3.5" Rubicon lift,


I know the tires look out of place, but that will come in time. Well I noticed that my driveline around 30 mph shakes, but it goes away. I talked to the shop that did the work and it does occasionally happen. They suggested I do a slip yoke eliminator and a new drive line which would fix this, or lower my transfer case (I would rather not having things lower to the ground IMO). I guess my question is will this fix my issue, 2 is it okay to still drive it (dont have the cash atm to just fix it). Am I still going to have the flex and everything that should be correct? I guess I dont fully understand what the slip yoke eliminator is suppose to do. I know it gives your driveline a proper angle, just it seem's to cost around 600 buck's or so for the parts to get it done(including new driveline). Any help would be apperciated.
