So I Replaced My Rotor, My Brake Caliper Mounting Bracket And Pads And The Noise Went Away And 2 Days Later I Got Another Noise Sounded Like It Was My Differential Checked My Drive Line For Play And Slop Nothing Everything Was Tight Just By The Sound I Had To Pull The Drive Line And Sure Enough My U-joint Was Seized Up And The Dif Side What Is The Point Of Ford Not Putting Any Grease Zerks On The U-joints

 

Its the same reason why they don't put them on the ball joints. So they can charge you to replace them.

 

Saves money on the Assy line. Don't have to have a machine to put the zirk in dont have to have another to grease it after its in. Less product, IE grease and zirk fittings.
