JK Front Driveshaft (Adams)
After lifting my ‘13 Rubi 3”, I knew the stock DS was on its last days. I ordered the Adams Front Driveshaft with grease fittings. Start to finish took 2 hours. Removal of the stocker is straight forward. You’ll need Red Locktight, Black RTV and an 8mm socket to remove the Transfer Case flange a 15mm to remove the diff end bolts and lastly a 32mm for the xfer case flange nut and a Tq wrench.
I jacked up the right front wheel so I can spin the shaft using the transfer case to lock into position.
I used a non-impact 32mm socket (impact sockets are too thick to fit the hole) I used the impact to remove the nut off the xfer case flange (the Adams comes with its own flange), tap the flange off and save the big black o-ring for later. Take the new Flange, clean any metal shavings or oil off with brake cleaner, place the big o-ring in the open space in the front, stuff it down as far as possible to make getting the nut on easier and put some RTV in the xfer case nut flange (this keeps the fluid on the correct side!) and some red RTV on the nut threads. Place the new flange and nut on the xfer case shaft, tighten a few threads by hand and run down with the impact. Torque to 160ft pounds.
Slide the new driveshaft up to the new xfer case flange, put red lock tight on the 4 small 12 point bolts. Put in all you can, starting as many threads as possible. One may be hard to get to. Make certain the u-joint sits in the flange correctly, there are tabs so you really can’t do it wrong. I used an 8mm ratcheting wrench to run the 3 down I could get to. There’s no torque, just get them Tight. You may have to put the xfer case in low to keep it from turning as you tighten. Then take it out of Gear, spin the front wheel till you can get to the last bolt. Once they’re all in go to the diff end. Cleans and put red lock tight on the bolts you removed and have them handy. Place the front flange on the diff, I use the same pattern as the old one for placement, it really doesn’t matter, put the bolts in a few threads then run them down with the 15mm socket on the impact. Torque to 80ft pounds. Go around and ensure all the bolts are tight!
Clean the area where you want to put the sticker on and slap it on. You have completed the install!
I have a Dana on the wife’s ‘16 JKU front and an Adams on the rear, wish I gone Adams F/R. I’ll be adding an Adams to the rear of mine soon.
