Just had both diffs rebuilt on my LX570 – night and day difference
I've been dealing with a slight vibration and occasional clunk from the drivetrain on my 2011 Lexus LX570 for months, and two different shops told me it was just old fluid. Finally got sick of guessing and took it to a place in Mussafah that specializes in heavy SUVs, and they diagnosed worn bearings in both the front and rear diffs. Ended up paying for a full rear and front differential rebuild service for luxury suvs at Al Zaabi Auto Care after a friend recommended them, and honestly I'm shocked how quiet and smooth the car feels now. They showed me the old parts – the pinion bearings were pitted and the carrier bearings had play. Took three days total and cost around 4500 for everything including new seals and synthetic fluid. Way cheaper than a new diff from Lexus. If your big SUV has a low growl or vibration on acceleration, don't ignore it like I did. Anyone else had diff issues on their older Toyota or Lexus trucks?
