I agree with what SidecarFlip and Mark posted. I have ARBs on the front and rear of our 1998 Jeep. I’ve never had a problem with either end. ARBs are a very well engineered product.
One thing I will add. If you have never driven a vehicle with an ARB in the front axle, you will definitely know its there when it is engaged. Your rig will want to go in a straight line, so turning requires more steering wheel input and still your rig will only turn about ½ as sharply with the front locker engaged. It will also put more stress on your steering components when you are turning sharply with some traction. If you are on something slick like wet muddy limestone, the steering doesn't bind up.
I don’t engage either ARB unless I need to get over something. If I can’t get over it open, I will usually try it with just the rear locked. With both locked, steering is an issue. You kind of need to be pointed in the direction you want to go.
We also have the factor e-lockers on our 2015 Jeep Rubicon. It drives similarly to the 98 with ARBs. The main difference is I don’t have to wait on the ARB compressor to pump up and I don’t have to worry about blue hose issues.
