Hello guys. I have a losi 5t with a rcmax 40gt engine. I just recently upgraded my carb to a wj-71. I KEEP snapping dog bones. Some people say to keep my locker. That its not the locker. Than some people say it is. I have to buy new diffs. Whats the best diff ml of silicone oil to use if i was to keep the locker. Whats the best to use in oil wise if i was to take the locker out? I run a 28 pinion and a 56 spur for gearing. I do not bash or jumps of any kind. I run on flat grassy fields. Can i get some opinions please thanks guys for the help
