    Ok, I went out mudding tonight. I just got a new front drive shaft so it was my first time in 4 wheel. after a couple of runs though some mud, i noticed a sound coming from my front end, its an intermitent noise that sounds like something rubbing. The faster i go, the faster it goes. When I unlock the hubs, it goes away. any ideas? Ill try to get more info on it tomorrow, get a good visual inspection. /forums/images/graemlins/1zhelp.gif

    When I have that noise its ussually a u-joint pooping out on me. It could be many things like axle shaft bearings or something. Maybe take the driveline out and lock in the huble and see if there is still a noise or not.

    Could have a clump of mud rubbing on the brake caliper as well.

    Yeah, but then the noise would be the same whether the hubs were locked or not...I'd check U-joints and junk too.
