Need help pressing on new drums!

NEVER use an impact wrench to "tighten the h#ll" out of your wheel studs! You will overstretch them and cause very tiny cracks in them. Then one day while you are toodling merrily down the street, your front wheel is going to go a lot farther than the rest of the truck will.

I would recommend taking the drum (after you have separated it from the hub) and a new wheel stud to a machine shop and have them slightly enlarge the holes so that the studs will fit through the holes without having to force them, but not be sloppy loose.
Do this for both drums.
Or if you have a decent sized drill press, buy a step drill and do the same thing at home.

The front drums need to be "pressed and sweged" to the hub. I used to do this in an auto machine shop years ago. Chevrolets and old Jeeps are the only ones with front drums that slide on and off the hubs. On everything else the hub and drum assemblys were held together by the studs being pressed through and then the shoulders by the knurl mashed out to hold them tight. From the factory you'd see four notches on the stud shoulders were this had been done. We even had a special cutter to remove this when replacing the studs. You knew you had it right when you tapped the drum with something it would ring like a bell. When they were done wrong you would get a clank sound from the hub not being tight. Back in the day I even saw some that weren't done correctly come apart. Find an old-timer shop to do this, they should still have the tools and the know-how. I don't know why everyone nowadays trys to put 'em together like Chevy's. Hope this helps.

Because once the wheel is on, it works just fine...
