Dave Call

Many of you know Dave Call as Doc, but after this article, you may know his Yellow Unlimited better than you’ll ever know him…

Doc’s 06’ Jeep Rubicon Unlimited utilizes a 6-speed manual transmission and flexes through incredible obstacles with a TeraFlex 6” MAX-LCG 4-link Long Arm Suspension Kit incorporating the TeraFlex High Steer Conversion and TeraFlex Quick Disconnect System.

Doc runs 37” Toyo MT’s on Champion Bead Locks. For rescuing his friends, he bolted on a Warn HS-9500 Winch, and for rescuing himself… he has a RockHard bolt in roll cage and Poison Spyder Rocker Knockers. Not forgetting his undercarriage, Doc has the full TeraFlex brand skid plate line protecting the engine, transmission and gas tank.

Doc has a built drive train with a Dana 44 in the front with Alloy USA Chromoly axle shafts, a Dynatrac diff cover and 4.88 gears. As far as the rear axle, this was Doc’s only weak spot. After breaking his Rubicon 44 rear axle multiple times he brought it in to TeraFlex PLUS to be replaced with a TeraFlex CRD60R - unbreakable even by the toughest of rock crawlers. The beefy CRD60R bolts right on and with extended brakelines, Doc was ready just in time for last weeks trail run to Five Mile Pass.

On the trail run Doc was asked if he felt any difference with the new Tera CRD60R. He said his confidence was”through the roof!” No more walking on eggshells; it’s game on for the Unlimited. Doc has always been a ‘no fear’ guy, but now his drive train will hold up to his conquer-all driving style.

Along with the new CRD60R, Doc had a new Tattons driveline installed. The higher pinion on the 60 helped with his pinion angle problems. Now even with his 6″ lift, he has no driveline vibration. He also had a 1350 u-joint put in on the differential side and changed the yoke on the front to 1310 in order to run u-bolts instead of straps offering more security to the yoke.

With a Rubicon 4 to 1 transfer case, Doc is now ready to hit the trails with even more confidence.
