2004 Sport Trac, Clunking noise in front end when in 4wd

[04 ST 2]

There is a loud clunking noise coming from the front end when in 4WD in my 04 Sport Trac XLS. The clunking noise happens when the truck is in slippery mud / snow / off road conditions. The clunking continues if I try to accelerate. Clunk - Clunk - Clunk. It almost sounds as if the front is "slipping"??? Please help! Thanks!

UPDATE: I noticed a broken / cracked bushing on the long bracket that goes from the front differential and mounts to the frame towards the rear. Could a bad bushings cause the clunking / binding sound? It only happens in 4wd, so I am not sure? I also re-created the noise by turning slightly on pavement at low speed in 4wd. The front wheels seem to still turn and the cv / u joints and axles / driveshaft (drivetrain) all look good. The bracket looks difficult to remove. Can I just replace the bushing while the mount is still attached to the truck. Do you guys have a part number or a link to the bushing? Any other busings / mounts I should look out for? Thanks!





Here is a pic I found on the internet of the bushing in question:
