[QUOTE="zombiekiller, post: 1428977, member: 25186"] if it fails locked, the only thing 4A would do is send power to the front if the rear started slipping. If the solenoid or check valve fails, then both iwes will be locked and thus will spin the front axles. if you leave the truck in 2wd, you don't run the risk of power being transferred via the tcase to the front of the truck. It will behave the same way that a truck with iwe eliminators behaves. Thank solenoid impacts a lot of other systems if it fails, including the brakes. I found that out the hard way when mine fell off my truck around Guerrero *****, and I had to pump the brakes 4 times before they would start to grab. In a pinch, you can fold all of the vac lines over themselves and zip tie them shut to seal them and the brakes will be at about 80%, but the computer won't be able to vary the precharge until you replace the solenoid.
