Selec-Trac doesn't have a viscous coupler, just an inter-axle differential.
Chain sounds likely too, but I'm still betting on exhaust hitting the body.

Re: Repetitive clunking in 4 wheel drive
My bet is on a u-joint gone bad.
If the exhaust 'is' hitting, then check the engine mounts out
carefully. If the driver's side one goes on a 4.0, the exhaust will hit
the front driveshaft when under torque.
