The rear knuckles have a casting defect that does not allow the lower most forward control arm bolt to be tightened fully. This causes the bolt to be 1/8” from being fully tightened. After removing the casting defect you are able to tighten the bolt fully. The bolt broke off in the knuckle causing the tire to point away from the body at a 45 degree angle. If my wife was on the interstate doing 60 when this happened it could have been life threatening but she was only doing about 10 when it snapped.
