with help from a second person i isolated the noise and it's definitely coming from the rear diff'. just to remind - the noises only comes when i put into reverse from D
so how do i determine if the noises I'm hearing are normal? i mean - when i installed the locker the backlash was perfect, can a backlash change over time?

 

we just had a problem like this at work, i think the tech said something about the pin in the carrier can cause it to make noise only in one direction, ill have to ask him what exactly it was

 

that will be great, i don't mind the noise as long as it normal for a Detroit locker, but if it's not then I'll open the diff'.
so I'm waiting for your updates, thanks.

 

well found out it was caused by the govbomb not the pin, sry could help ya out
