I've got 3 bad lugnut studs on my front axle...the lugnuts won't tighten up. I changed the rear ones before using the old "knock em' out with a hammer and pull the new ones in using washers and tightening the lugnut" method. How hard is it to do the fronts? Do I have to just pull the hub and rotor assembly off the spindle? Or do I have to split the both of them? Or is there a way to punch em' out still on the truck? Thanx for any help, and HAPPY MUDDIN'
