LX 570 Vibration at Highway Speed (4 Viewers)

Also FYI, if you've got pulsing in the brakes, it's not always a warped rotor (or rotor in need of re-surfacing). More often it's deposits of pad material from somebody abusing the brakes (riding the brakes down a mountain pass and then coming to a stop with their foot on the pedal while the brakes are super hot). Before you resurface or replace your rotors, take it out on a country road and do a handful of HARD 60-5mph brake stomps (do not come to a complete stop). Might fix your problem for free!

Thanks, look forward to hearing your update. I also ended up buying a full fresh set of OEM tires at a very aggressive discount (guessing they don't sell a lot of those Dunlops) to see if it makes the difference, awaiting delivery. The dealership is fully attributing the vibration to the tire age differential / wear (2 are six years old (life of the vehicle), 1 is 3 years old, and 1 is the new one I got). I am going to replace all the tires and move the newest of the current set to the spare position.

I'm more

If that doesn't work, I'm kind of at a loss, will have to check with another mechanic or two and consider giving 17-18" wheels and a fatter tire a shot prior to giving up altogether. That would be sad though, all in all love the lx, but the vibration is notably worse than my Rav4 and really kills its benefit as a road trip cruiser.

Thanks for this clarification on bedding. Unfortunately didn’t fully understand at first, so I think replacement is already in progress. Moving to a place with a garage soon, so hopefully can start picking up on basic maintenance myself in the next few months to avoid the wild costs.

As an update new rotors fixed the braking issue.

For the road vibration I had all tires switched to fresh and the spare wheel swapped for one that was likely slightly warped. Everything was road force balanced. The body still vibrates and linearly increases with speed. Looking at the passenger seat or resting my head back demonstrates a small high frequency vibration that is notably worse than my rav4.

I’m starting to wonder if this is just to be expected on the stock 21” wheels. I’m going to test drive a similar one to find out, but if it’s unique to mine not really sure where to go from here.

Yeah just drove a similar 2018 model. Very similar but higher mileage and better tires on the same size wheels (defenders). It did seem to ride a bit better…
