I installed the N3 steering stabilizer on my 2018 JL instead of going in for the V41 recall. It did firm up the steering, but it was pulling to the left when braking. I switched to the RC dual steering stabilizer and the steering is firm and does not pull when braking.
My wife just had this happen to her on Friday morning and again this morning. Both times temperature was in the low 30's. She was going around 60mph turning left and both times the steering locked up. Pretty scary. Jeep is a 18 sport unlimited.
