Complaint Summary
POWER TRAIN
Owner Narrative
Rear Axle is grinding. Took vehicle into dealer and it is the well documented rear axle issue but this vehicle is not included in a recall. The differential fluid was replaced and figure 8s were done but there is still grinding. The rear axle also drags at times when in auto 4wd. The dealer said the next step would be to replace the axle. This is the issue: Differential Noise/Failure: Reports indicate a rubbing noise while turning, often attributed to the rear differential. In some cases, the entire rear differential has required replacement.
