Driving in the snow today I had my jeep in 4WD on the highway. At anything above 40 mph I'm getting a grinding/clunking sound any time I go from off the gas to on, and vice versa. When there is torque, I hear the noise. When I let off to coast, I hear the noise. Anyone else had a similar problem? Shall I replace my front u-joints? Thanks in advance. Evan

Check your U-bolts too. I bet your axle pinon is changing under load because your u-bolts aren't securing your axle to the leafs. Either way, I'd recommend gettng a buddy to hold down on the brake and goose the gas while you watch the drivelines. Pay close attention to where the rear driveshaft meets the rear axle pinon.

Check your Sway bar links in the front,,you may have a broke one
