The right front hub won't engage in Auto. The truck is making 14 inches Hg. I used my vacuum pump to apply up to 25 inches HG hub still wont engage. I can put it into lock manually just fine. The hub holds vacuum. I recently did the ball joints on this truck, and subsequently had to replace all the seals in the steering knuckle. Could I have put the hub on wrong? I'm really lost. Not sure where to look next.
