I have an '03 Hemi QC an I am getting crackling or squeak coming from the front of the truck when the suspension gets compressed and when I turn sharp. For example, if I am going about 5 mph and I yank the wheel I get a little crackling sound. I can also go over a road hump (large smooth speed bump) and the suspension kind of creeks. Does anyone know if there is any grease fitting under the truck that I need to tend to? All ideas are appreciated. Thanks.
