ive got ruff stuff control arm mounts on my 90. I was out at creekside romping through some water and there was a deep pothole, the passenger tire went in and the whole jeep stopped, back tires came off the ground and i bout went through the windshield lol. went out and looked and the whole mount had ripped off the axle. Had a 4x4 shop in houston install for 80 bucks.
