Rear Axle Whine
Has anyone experienced a rear axle whine above 70mph? I've noticed a whine while just slightly on the gas above 70mph (maintaining speed). Does the GX have a regular ring and pinion set up or is it a more complicated affair?

Yep, whine here too. Only when lightly on the gas, take foot off gas and whine goes away. Mine can be heard at all speeds though. Especially in the mornings
I also notice the tranny doesn't like really cold weather either. In the mornings or afternoons (if it has sat all day) the transmission lags and then jerks into 1st gear from reverse. It also does not shift real smooth either when cold. By cold I mean OAT of 40 degrees and below. I think this tranny would benefit from synthetic fluids.
All the demons in my GX comes out in cold weather or are more pronounced. It really sucks especially since I take it to the mountains almost weekly where it's normally 20 degrees or colder in the mornings.
Lexus did a shotty job at best on the GX.

This sounds like the vehicle drivelive vibration everyone has been talking about. Curious that you think, or describe it as rear axle whine. What makes you think so? I don't disagree or anything but wondered why you feel that way.
As cessna says, you must be on the gas to hear it. But maintaining vehicle speed on a flat road surface sets up about 10% throttle and the perfect conditions for this whining on and off noise. I notice it at around 55-80, mostly around 75-78mph.

The Tranny does not like cold especially the temps you mention, if you slept outside in 40 below could you wake up and run a mile, letting it warm up will alleviate the problems, not shifting, slow shifts when cold is a common problem among all vehicles, the fluid has to warm up to flow, put a quart of trans fluid in the freezer over night and then compare it to a quart your left on the table, it's like molasses
If you want Synthetic Trans Fluid, Amsoil meets all of Toyotas requirements
don't use Mobil 1 or anything else it will just shift harder

I doubt it's the rear axle, is it under you and more like a hum, then thats probably normal mine did it a little when new then stopped, both my Pathfinders hummed when in 4wd.
With the radio on I could not hear it

Again something I find myself repeating too often for a 50K Lexus.... This thing was released a year too early and without the proper R&D.
And again just my .02 or is it more like my 50K.

Dear edge,
I can understand a Pathfinder having rear axle whine but not a lexus. (actually the pathfinder shouldnt have it either!!). This is not a hum or a vibration and has nothing to do with the transmisssion, greasng up the yokes or adding lube anywhere. Im amazed at the limited amount of automotive knowledge on this board (sorry guys - not looking to flame anyone). This rear axle whine is from the rear axle and sounds most like a set of ring and pinion gears set up incorrectly. As I said before - I dont know what type of rear the GX has and that's what I wanted to know. Is the torsen a ring and pinion set up?

Thank you 177 the dear was sincere Im gonna say it's not your rear it is the front, almost at the same time this thread was started a 4Runner owner started a thread on yotatech.com about the same problem, he had the whine at above 80mph, at 1st the dealer refused to test drive his vehicle at that speed but he drove it with a tech who noticed/heard the problem and they have not fixed it.
His solution was/is to vandalize the dealership that sold him the truck.
Has your dealer recognized the problem or refused to test it at that speed, which you would have to drive then with a tech, I did take my truck up to 85 and held it their with no radio and windows closed had no noise.
You can always take it to another dealer

I tried my dealer. No luck. I also noted the vibration and the kick in the back when letting off the brake. Their response was (no problem could be found)...I dont know if another dealer would be any better though...

The "kick in the back when letting off the brake" is an easy fix. Mine was fixed a few month ago. Also read other members got this problem fixed. You should try other dealers.
About the vibration, I noticed vibration from the floor when I turned the wheel about 180 degree (0.5 turn) and applied gas. Have you guys experienced this?

The noise doesn't seem to be abnormal as it is fairly quiet and I just chalked it up to being a 4 wheel drive truck. It's not going to be as quiet as GS or ES. Plus, I do have a set of AT tires on it, which do groan as I'm rolling, but I am 100% sure that the whining sound is something in the drivetrain. Just need to know if others experience this and if its normal or not.
Any help would be great. Thanks all! -Will
