Hellwig sway bar 7596 has heavy duty 4140 chrome poly steel construction that is powder coated. The sway bars end tabs are forged into the sway bar instead of welded. Hellwig sway bars have stronger construction, solid hot rolled steel, and a longer life then stock. Please call us at 1-800-358-4751 about your front axle. We are not sure what the problem is. Thank you.
