Same happened to me with the stock a-arm. My question is how hard is it to swap them out?
its only like 5 bolts or something... unbolt from bulkhead, shock, swaybar, spindle. might be tight getting the old bent one out... put the new one in, bolt up and go. pretty straight forward
and to build on my other comment before... that is how a failed a-arm should look. buckled in the rear and still attached in the front.
