unless you have done the grey wire mod the rear locker wont be engaged at 80mph, since it only will engage when you are in 4lo. If you locked it when in 4lo and then shifted into 2wd ( i assume since you are doing 80mph) the light will blink.seth_js said:Does the stock rear locker automatically turn off once you hit a certain speed? I forget about it all the time and don't notice the blinking red light until I'm doing 80mph on the highway.

I don't know of anyone who has actually broken one like that, but it is extra stress on the axle, which can't be a good thing and I couldn't tell you how much it might reduce the life of the axle (more stress = less fatigue life).seth_js said:Yeah, I'll engage it when in 4lo, and then forget about it and go back up to 4hi, and then eventually 2wd when back on the highway. So that won't do any damage to it? What is the grey wire mod?
