Part-5 of the installation of the Rubicon Express 2.5" Standard Suspension System.
I ended up installing the transfer case lowering kit after driving the Jeep for a couple weeks. I was getting some minor driveshaft vibrations at speeds over 65mph and when letting off the throttle/decelerating. I will be installing my other transfer case with SYE installed and running a shortened Jeep Cherokee XJ front driveshaft in the rear of the YJ after my axle swap. At that time I will be removing the transfer case lower kit.
Vehicle: 1991 Jeep Wrangler YJ 4.0L/AX15 Lift: Rubicon Express 2.5" standard suspension #RE5505 Wheels: Factory Jeep TJ Rubicon 16x8 Tires: 265/75/R16 D Load Range BF-Goodrich All-Terrain T/A K/O
Update: Due to the t-case lowering kit making shifting into 2nd, 4th, & Reverse very difficult I have removed it and reinstalled my other transfer case that already has a SYE installed. I am now running a shortened XJ front driveshaft in the rear of the YJ. No vibrations with the new set up either and gained more ground clearance by putting the skid plate back up where it belongs. It couldn't wait until the axle swap and I will show it in an upcoming review video.
