We took our Ranger in on 11/28/01 because there was a squealing noise, service derpart. Could not hear it. Took it back on 01/07/02 because noise got worse. They found that there was no grease in the inner bearing on both side of the front wheels "see other complaint odi 734299 from someone else" it has feathering and cupping on the tires also they cant seem to fix. . They also found on 01/07/02 that the seal on the assembly transmission extension was leaking. It had a flange seal put on the differential at 2945 mile, the other side of the drive line. See my other complaint odi 754342. Transmission went out at 2945 miles. We feel this Ranger is unsafe to drive.
