NHTSA Complaint #11571331 — 2016 TOYOTA SIENNA

After 80,000 miles have a loud whirling sound coming from rear, after inspection and online investigation found many many others with same issue, the dust cover and or o-ring doesn’t properly protect the rear bearing in the coupler. So while the fix is to remove the rear differential coupler, and replace the bearing with an improved version, seems Toyota has stopped supporting this, and no longer offers the improved bearing as a replacement part, but only supports replacing the entire rear differential coupling at $2000 for the part plus labor. While many have replaced the bearing without issues despite toyota not allowing it as a fix. So first it should be a recall as this is an obvious defect effecting thousands, but then to gouge owners for thousands when the fix doesn’t require a complete replacement of the rear differential coupling assembly.
