Front calipers banging around

[Flyscooby2]

Hey Fellas:

 

I can't figure out why the two front calipers keep bouncing around causing grinding and loud thunk sound on my 86 GL wagon. As I speed up the sound disappears. The driver front is new rebuilt from parts store. The other side did not seem to have a sticky piston. The mounting pins seem to be ok (lubricated them with the correct greese) The only possibilites that I have though of thus far are:

1:) I did not set the pistons correctly

2:)Did not set emergency brake correctly

3:) To much torque on main axel nut (it seem to not do it as much when the axle nut dose not have much torque)

4:) The uncarriage has to much rust and its loosing its geometry.

5:) Motor mounts bad throwing axle out of alignment

 

Do I need my soob die before I do?

check to see if the metal clips on each end of the front pads are on right.I've never had a problem with torquing the hell out of the axle nut except for when I have to change a shaft out on the trail.

Are you talking about the lower bolt (not the pin) holding the caliper on. If that is the case it is there tight. What dose "BTDT on the REAR!!" mean? Could this be strut problem?

They have a loud thunking sound...with no clip could this make this loud thunking sound? THE CLIPS ARE ON CORRECTLY It appears to drag as well.
