So I found myself questioning where i should be jacking up my jku safely when installing my ball joints, tie rod and drag link.
Im looking to install a lift kit myself in the next week or two so I decided id try and get some advice as to where I should be jacking from to get the best clearances and to do it safely without damage.

 

Put some stands under the axle.

 

Axle works for your front end work, but you'll need to put the stands under the frame for lift install.

 

Under the frame, right by the control arm mounts for your lift. Under the axle tubes is acceptable for your axle work (as described in the FSM)
