Thanks for everyone's patience with my questions and responding. So to lock the center differential: Step 1 - remove the front drive shaft. Step 2 - Start the car Step 3 - shift transmission to neutral Step 4 - wait for blinking cluster light to become solid Step 5 - Shift to drive and then to...

Based on the google search, it is saying "Never use the center lock on high-traction surfaces like dry asphalt or concrete to prevent severe damage to the drivetrain. Use for low traction: Turn it on only when driving on loose or slippery dirt, mud, sand, deep snow, or rock crawling." Does it...

Can you provide the instructions on how to lock the center differential? I left the car with them until they figure out a way to test the front shaft.

He said they removed the drive shaft and the GX would not move at all. I'm sure there is a way to do that but maybe they don't know how to...

I must have missed that. I just asked him to run that check now.

Quick not so good update... Dropped the car couple of time at an independent mechanic who is really really good and has experience with lifted trucks. He performed all sort of tests on the lift to isolate where the vibration was occurring. He put on the OEM tire/wheel set on my car put it on...

Good point, and I will look into that. I got the suspension/wheel related stuff checked by a mechanic and I do recall asking specifically for wheel bearing and they said no issues. Wondering if your mechanic found any play in it or if they seemed very worn off? Do you have the part number for...

Those are both good suggestions. I was actually thinking about swapping the wheels/tires with another set if it is locally available to borrow from somewhere. That way the this issue will be isolated for sure. Will report back when there is an update.

Some bad news - replaced the driveshaft with a new OEM and it did not reduce the vibrations at all at high speed. It made a slight difference where the car seems smoother/quieter when driving below 40-50mph, but as soon as it goes above 60 it starts vibrating on the floor/seat. and especially...

One thing someone said online is i can test to see if driveshaft is the issue by putting the gear in neutral at high speed like 70mph and see if it affects the vibration, and then put it back in "D". I just wan to make sure if it is safe and not going to break anything?

Really appreciate your advice. Since money is tight, let me just get done with the RFB on the rears which isn't costing me anything extra at this point and then go straight to driveshaft after that.

Good point. And this is what I'm really leaning towards as well because I'm running out of options at this point. The only thing left is road force balance in the rear but after not experiencing any improvements with the fronts (which the tech said needed it) I'm not sure if doing the rears...

No changes to the wheels, tires or lugs for a while when this started happening. Everything has been very well maintained and I've had the same suspension with Method wheels for 5+ years without any vibration issues until now. The tires were replaced a year ago with same Wildepeak AT 285/70.

I have a lifted 2009 GX470 with 270k miles that was driving smooth forever until April, this year and this problem is not going away. The vibrations are primarily on the floor and then also felt with the seats. The steering does not shake most of the time. I've gotten the tires balanced 3...

I installed the original TRD style grill when it came out few years ago along with the 3 raptor lights that came as a package. Now, one of my raptor light is flickering and it is time to replace. I need a plug and play that fits in the existing harness which is already wired. Does anyone know...
