After much trial and error of trying to get my cetner diff lock to work so i can actually lock my front and rear diffs i have decided i will take it to a shop to check it out. I'm not 100% sure if its the acuator for the CDL but i'm betting it is. Does anyone have any idea of how much it may cost to fix this. of course if ioverlooked a connection it may cost nothing but if it is going to involve rebuilding part of CDL system i'm just curious as to how much it may cost. If anyone has a ball park figure that would be great. i'm not looking for any exact just rough like under 500, over 500, over 1000. Thanks
