Evening, sorry you experienced this.
Honestly, I can’t make any assessment on your bushing given the grease that still is in the bushing.(just can’t see the actual bushing)
I to am a firm believer in wet bolts and regular greasing, so I sincerely hope I don’t have this to look forward to down the line. I only have about 2200 miles on mine at this point.
In the what it’s worth department, are you sure you are using an EP(extreme pressure) grease that is appropriate for suspension applications. Different types of grease are specific to a purpose, not implying you used something incompatible, just making a comment for educational purposes.
So, can I ask how did you address this?
Why was your axle replaced, how was your bushing wear addressed?
