Afternoon Everyone,

I've got a recently lifted 2012 JK Unlimited. It has a 4" TeraFlex with front-lower and rear-upper arms. I'm a bit stumped as to what to do next. As far as I see it, I have two options:

1). Purchase the remaining four control arms (front-uppers and rear-lowers) from TeraFlex. Get suspension completely dialed in.

2). Purchase new front/rear driveshafts and eliminate that from the "worry" list.

I know it would be ideal to do both at the same time. I'm afraid I just don't have the funds at the moment. In my mind, it all comes down to whether or not front-lower and rear upper control arms are sufficient for installing new front/rear driveshafts.

Do I need all 8 control arms before I can even start thinking about properly running new driveshafts?

Any advice/suggestions? I thoroughly appreciate it.

 

Go with a driveshaft first. That 4" lift will almost certainly force you to do an aftermarket (=smaller diameter) front driveshaft. I am assuming you have not been offroad with your JK yet? If you have, you would almost certainly have heard your front driveshaft making contact with a crossmember. The rear driveshaft, you can run that one until it eventually goes bad at some point, all the while saving for its replacement.

 

Agreed, drive shafts then lift.

 

Appreciate the responses. No, I haven't been offroad post-lift install. I am aware of all the DS issues caused by the lift, and thus haven't disco'd at all. Shafts are checked regularly, and I know they will fail even on-the-road due to prolonged use in a "pinched state."


What it all comes down to is this: Can I properly install an aftermarket front driveshaft without front-upper control arms? ?

 

You sure can, because the new driveshaft will be measured to fit based on the amount of lift you have. You are definitely going about it the correct way, research and then purchase. At some point, definitely close the gap on getting those adjustable control arms to address the pinion/caster angles. Good luck brother
