Maybe your hinge pin is bent causing the breakage?
Tower hobbies part number:TDRC8309 Team Durango upper suspension hanger & insert set.What you have to do to make it work:The Durango hanger doesn't work like the arrma version.It uses inserts and is captive from the other end which wont't work on the stock setup.Easy mod,requires two plastic spacers and two 4mm locknuts that fit your stock pivot bolt.For spacers i used quad blade adapters,i believe are 10mm od x4mm id.I used my vise to press in on one side and the nut just sets in the other end( the red bracket keeps the nut from falling out till you start the bolt).In the above photo you can see i also use the blade adapters to take up the extra slack.This system took out alot of front suspension slop/twist and with the shocks disconected i can tighten the suspension bolt now threaded into a metal locknut and its stays set!
