Frizzy Posted June 11, 2023 Share Posted June 11, 2023 Hi everyone, I've noticed a slight juddering but only in 3rd at around 80mph it's not wheel wobble coz it doesn't happen at 80 in any other gear and it's not engine related as it doesn't happen at any other rev range, I'm thinking gearbox related but wanted to here other thoughts first before delve into that Quote Link to comment Share on other sites More sharing options...
evinX Posted June 11, 2023 Share Posted June 11, 2023 Possibly the gearbox mount? As it has a thick chunk of rubber on it. They do wear. Worth getting it on a ramp and checked properly Quote Link to comment Share on other sites More sharing options...
Scooter Posted June 11, 2023 Share Posted June 11, 2023 some potential info here? Clutch down at 80mph does it go away? https://www.clublexus.com/forums/performance-and-maintenance/441880-w58-whirring-noise-all-gears-but-4th.html Quote Link to comment Share on other sites More sharing options...

Worth getting it on a ramp and checked properly I would've thought it would be in all gears at the same rev range if it was the mount but I'll give it a check anyway cheers Quote Link to comment Share on other sites More sharing options...
