Ok, as many of you know,I had the rear diff fixed about 2200 miles ago. Now between 65-70 it is howling a bit. . not real bad. . YET... . took it in for another issue and had them check it again. . they heard the noise and said " Normal" and that " I had lots of warranty left" ... I explained how on here TDR members were having the rear axles replaced... they refused to do it at this time as the noise did not warrant it. On the ticket it says " Could not replicate customer concern at this time" How can I force them to replace it?? Call D/C????? THanks!!!
