Jeep Wrangler JK 5 Tire Rotation
Having a Jeep with 5 full size tires means that tire rotation should include the spare. While some Jeep owners choose to leave out the spare in rotation for varying reasons like different size/type tire or thinking it will save the spare from wear. We believe that if your Jeep has a matching spare you should run it through the rotation. Read more

Driveline Angles – Part 2
With all of the angles recorded, complete a drawing as shown below. There are no u-joint operating angles in your drawing at this time, jut the slope of the components and their direction. To determine u-joint operating angles, simply find the difference in the slopes of the components.
When the slopes are in the Same direction on two connected components, Subtract the smaller number from the larger to find the u-joint operating angle. When the slopes are in the Opposite direction on two connected components, Add the measurements to find the u-joint operating angle. Read more
CJ Transmission Swap 5 to 4 Speed
QUESTION: I have a 1983 CJ-7 with a 258 six. It has a T-5 five speed transmission with (I believe) a Dana 300 transfer case. The transmission blew apart and I need to change it out. Do I have to change the transfer case too or will the Dana 300 bolt up to a Jeep 4 speed? The front axle pumpkin is on the passenger side as you look at it from the front.
ANSWER: Your Jeep should have a Dana 300 transfer case and since you mentioned that it has a 5 speed it’s about 99.9% sure that it’s a Dana 300. Yes a Jeep 4 speed from similar years will bolt to both the engine and transmission without any special adapter. The problem will be is that most of the Jeep 4 speed transmissions are shorter in length which will cause the rear and front driveshaft to not fit without modification. There may be other differences like where the shifter and transfercase shifter comes through the floor. Funny how a minor change can open a big can of worms.
See the Jeep Transmission Tech section for specifics on transmissions.
Teraflex Wrangler JK Leveling Kit Post Installation
The Teraflex Leveling Kit installation took about 3 hours at a casual pace. Our experience working with the JK helped us to get by the little tricky parts and keep moving. After the installation we double checked all the bolts we had contact with during the install including re-torquing the lug nuts after 50 miles.
Teraflex Wrangler JK Leveling Kit Installation – Part 3
Part 3: Rear Installation
Installation of this kit is pretty simple and only requires basic tools, a good jack, and good jack stands. Safety is top priority, make sure the Jeep is secured before working underneath.
Raise the rear of the Jeep and support the Jeep with jack stands placed under the frame rails just in front of the rear lower control arm mounts. Remove the rear wheels and allow the axle to partially pull away from the frame. Several items need to be loosened/removed to allow the axle to pull away fully. Unhook the parking brake cables from the bottom of the body and unbolt the upper sway bar links. Remove the bolt from the rear brake line brackets on both sides, pop off the axle breather tube, pop off the locker wiring retainer clip (Rubicon only), and pop off the wiring retainer clip for the axle sensor wiring. Unbolt the bottom shock mounts. Failure to remove these things may cause them to pull tight under the weight of the axle and get damaged. Read more

Wrangler JK Handling Problems after Lift
QUESTION: I recently purchased a 2008 4dr JK Wrangler from an out-of-state dealer. It has a 4″ lift with 35″ tires and KMC bead locker wheels. I have noticed that on long sweeping left turns the Jeep very often feels like you’ve gone over a patch of ice and it is unable to hold a line. It is very scary. Also very often the ABS brakes kick in for no apparent reason. The dealer is clueless. Does anyone know what this might be? Please advise. Chris P.
ANSWER: Often after lift a Wrangler JK the owner or installer overlooks the absolute need to correct the steering wheel alignment. The Jeep’s computer uses steering wheel position to determine the direction of the vehicle. If it’s off more than a few degrees the Jeep thinks it is in a slide and uses the traction control system to attempt to correct the problem. Adjusting the steering wheel position is simple. There is a threaded collar in the drag link. Rotating the collar will turn the wheel one way or the other. It’s usually easiest to have 2 people. One in the Jeep to observe the wheel the other turning the collar. See below. Read more
