JK Front Driveshaft Install Instructions.
The following are the tools and products you will need to install the driveshaft.
Tools: These are the tools we use for the install. We listed a couple of different tools that can be used to loosen or tighten the same bolts just in case you do not have some of them. Example [ You could use the metric 15 wrench to tighten the front bolts on the flange, or the metric 15 impact socket]
1/2″ Drive Impact, 3/8″ Drive Impact, Medium size Ball Pein Hammer, Medium Size Rubber Malet, 5/16 12 point end wrench, Metric 15 End Wrench, 1 1/4″ Impact Socket, 3/8″ Metric 15 Impact socket, 1/2″ Drive Extentions, and 3/8″ Drive Extensions.
Products: Locktight, Black Silicone, WD-40, and Brake Cleaner.
You will be installing the parts you see in the picture below. Adams Driveshaft’s Rock Crawler 1310 CV Driveshaft, 1310 T-case yoke, and four 5/16″ 12 Point Head Grade 10 CV Bolts.
Note: The Silicone and Locktight does not come with the driveshaft. It is only pictured to show you the importance of using these so you will not have a leak, or a bolt come loose.
Thanks to Becki Ortiz for letting us use her 4 Door JK for the install.
First you will need to take out the old OEM Driveshaft by using your metric 15 end wrench or using an impact with a metric 15 socket on it. You may need to spray some WD-40 on the bolts to help you remove them if they are rusted.
Using your rubber mallet or a medium ball pein hammer, tap the OEM flange on the side like the picture shows to remove the flange off of the front pinion yoke.
Next you will need to take out the other side of the OEM driveshaft by using your 5/16″ 12 point end wrench or an impact with a 5/16″ 12 point socket on it.
With the 1/2″ impact and the 1 1/4″ socket, take off the nut in the center of the transfer case.
With your medium ball pein hammer, tap off the front T-case yoke. There is a thick o-ring in the center of the yoke that you will need to re-use.
Take the o-ring out of the old yoke and insert it into the new T-case yoke that came with the driveshaft like the picture below shows.
Install the new front T-case yoke on the splines and then tap it on with a medium ball pein hammer, or Rubber Mallet until there are enough threads to start the nut.
Put black silicone on the washer of the nut like shown below and put some red Locktight on the threads of the nut.
With the impact and the 1 1/4″ socket, tighten the nut down until it stops. With a torque wrench, tighten the nut to 160 ft lbs of torque. If the nut is not tight enough you could have some vibration. We called the sealer and they said the nut should be torqued down between 120 to 200 ft lbs. We have found that at 160 ft lbs there is no movement.
Put some red Locktight on the four 5 /16″ head bolts that came with the driveshaft package.
Insert the CV side of the driveshaft into the yoke and screw the bolts in the back side of the yoke like the picture below shows you. Tighten the bolts using your 5/16″ 12 point end wrench. There is no torque spec for these bolts so make sure to use plenty of Locktight.
Next put Locktight on the four factory metric 15 head bolts.
With your impact and metric 15 socket, tighten down the four bolts until tight. Using a torque wrench, tighten these bolts down between 35 to 45 ft lbs of torque. We torque these down when the Jeep is on the ground. The picture below just shows you how.
You now have installed a new Adams Driveshaft Rock Crawler 1310 CV Driveshaft. This is one of the strongest driveshafts and is made with the best components possible by Spicer and Neapco.
