I would get them as aligned as soon as possible. If one rear wheel leads the other it could pull to one side or the other depending on which wheel leads. In our modified race car, we purposely set one wheel leading to make the car turn left easier, depending on the track banking, but this is with locked rear axles. Your Jeep will dog-track as well.
Where did you measure from?
