track bar issues

[losee5]

I have an 05 unlimited with a 6in fabtech long arm lift running 35s with a dual steering stabilizer. The upper drivers side bolt on my track bar snapped while backing up into a tight area and turning the wheel all the way to the left....i replaced the bolt, but I dont why after over a year the bolt snapped. I just replaced all my shocks with bilsteins 2 weeks ago and this is the only suspension mod ive made in a year. Anyone have ideas why this bolt may have snapped?:?|

Track bar too steep maybe?
