New member here. Been looking around and reading posts for a bit now. Lots of good info here.

Not a Lexus owner yet but I知 currently in the market for a GX470.

 

Welcome , time to scratch that itch!

 

I would perhaps say, seek out an older 460. 470's are getting into an area of full-on maintenance if the existing owner has not already done so.
But, this all depends on your ability to do work, or have $$ for a shop to do the work, etc.
By now, lots of 470 engines have lots of miles on them, so keep in mind engine mileage. I heading to 300kmi (at 250kmi now). Not 100% sure it will get to 300, but it's not being abused, so maybe. I have an odd issue in the driveline system, not sure yet if it's the trans or something other, some odd roll-on (moving and then you coast a bit) and then when I get back on the gas you can feel the slight bump as the power takes up the slack and hits in the system.

 

Great vehicles and I would not hesitate to buy a well cared for PPI GX. Bullet proof engine and transmission.

My GX that I bought new and now has over 200k miles on the clock and it is so reliable I had no reservations about giving it to my 17 yr old to drive.

 

That bump/slack feeling you are describing might be the well known clunk issue. When was the last time your driveshaft was properly lubed? There is also a replacement drive shaft that should eliminate the clunk if you wanted to do that.

 

Grease joints get grease 1-2x yearly. I replace diff oils on the order of 40kmi.

This "bump" has been a gradual thing. I never had the bump issue. So it seems the bump is developing.

I did try and locate a slack issue in driveshafts and the diffs, but can't really find anything.

At 250kmi the driveshafts are probably due for replacing.

 

If there is a technology expert at your dealership, request that they be available when you take possession of the car. They can go over all the technical features of the car and set up the car on your app. The technology expert at our dealership was extremely helpful and knowledgeable. Also, if you are sharing the car with your partner, it is really helpful for them to join you with the Lexus app installed on their phone as well. Having the technology expert show you how to move between the two user accounts is also very helpful. May you love your new 350h NX as much as I do!
