Backing into a parking spot I heard a clunk. After looking around I see the tierod hanging down. I was just traveling 70 mph not 1/2 mile before this happened. Not in a good mood. I can not afford this type of brake down right now, my OCD won't let me just replace the broken one, I'll have to do them all.

How n why this broke I haven't a clue. It's a totally stock truck no oversized tires no real off road driving maybe a few miles on a gravel road a few times a year.

The reason for failure on this style is quite simple actually, for those who don't know here is the cliffs notes.

 

The TRE on the drivers side is not your traditional 360° of movement/rotation TRE, but rather it only move in a line fairly perpendicular to the wheels. The pass side is a standard TRE.

 

When the 08.5+ steering is installed it is very important to keep the TRE's aligned and in the center of their travel. If they are properly aligned there is no binding as steering occurs. When they are misaligned the drivers side TRE gets stress put on the stud in a direction it wasn't designed to move, they then fatigue and fail.

 

The latest fix is a pin/grove setup between the TRE's so that they can only be installed with proper alignment, which should eliminate the failures.

Even thou the issue was known, and how not to have it occur, I have held off on upgrading my steering components. Now I feel like it wont be a big deal to upgrade when the time comes. So far 101K and still rocking the OE TRE's.
