NHTSA Complaint #10667419 — 2001 TOYOTA 4RUNNER

ON THE REAR END DIFFERENTIAL HOUSING, THE BACK COVER AREA (NON REPLACEABLE) HAS BECOME SO POROUS BECAUSE OF HEAVY RUST SCALING AND FLAKING THAT DIFFERENTIAL FLUID SEEPS FROM IT. THE REST OF THE DIFFERENTIAL HOUSING IS MADE OF THICKER, HEAVIER GAUGE METAL AND SEEMS OK. THIS ISSUE WILL CAUSE THE GEAR OIL TO DROP BELOW THE REQUIRED LEVEL CAUSING DIFFERENTIAL FAILURE OR LOCK UP AND AT HIGHWAY SPEEDS COULD BE DISASTROUS. WHEN I REALIZED I HAD THIS PROBLEM, I SEARCHED THE TOYOTA FORUMS ONLINE AND IT APPEARS TO BE A VERY COMMON ISSUE WITH THESE VEHICLES AND TOYOTA IS AWARE BUT WILL DO NOTHING ABOUT IT. THEY WILL REPLACE ENTIRE RUSTED OUT FRAMES ON TRUCKS UNDER RECALL, BUT REFUSE TO ADDRESS THIS ISSUE? TO ADD INSULT TO INJURY THEY WANT $3000 TO REPLACE A KNOWN INFERIOR/DEFECTIVE PART. I HAVE HAD TO RESORT TO MAKESHIFT REPAIRS USING BRUSH ON BED LINER TO STEM THE LEAKING AND CHECK THE FLUID TO KEEP IT FULL. BUT WHAT ABOUT PEOPLE WHO ARE NOT MECHANICALLY INCLINED OR WHO ARE COMPLETELY UNAWARE?
