All done, finished up last weekend. Quick paint job, remount and grease and we were back in the dirt last friday, the 27th. Everything held up great so far. I will post some pictures asap. Overall not a terrible repair and it sure beat paying $1400 for new loader arms.
I think the damage may have been done by too much back dragging with the bucket. I noticed the lower lip was tapered and worn. Guess a bucket lip and maybe some teeth next...
