4Lo gear whine? Does 4Lo and 4High use the same gear oil/case? (Silly Question?)

[SnoViking]

Ok. So before the flames and pitchforks come out let me explain the question;

Recently picked up a 2008 LX with about 130k miles. Based on the known fact that a little old Korean grandmother drove it before me, I’m fairy certain that the 4Lo has never been used before me.

(The first time I engaged the 4Lo is took a solid 30-40 seconds to engage. Now it takes a few seconds after engaging it a few times.)

I was out playing on the beach and decided to try the 4Lo just to make sure it works. Once engaged the truck drives as expected but there’s a good amount of “whine”. I was compare it to straight cut gear noise. It’s very audible. On my GX, and 4Runner, 4Lo was no louder than 4High.

I do have the transfer case/gear oils sitting at home ready to change but wanted to know how everyone else’s 4Lo sounds... I’m curious if it’s just lack of use and it will go away or if is damage something.

Advice?

4-Lo on the LC has a noticeable level of gear whine. I'd imagine what you're hearing is normal but that's hard say for sure without an audio clip.

I asked the same question a few months ago. The response was that yeah the whine is normal and it is because the low gears are in fact straight cut.

My 4 low whines a bit, its not a concern.

Flames and pitch forks! This isn't the 80-series forum...

So many whiners in this forum! Hehe
(Yes, you’ll hear gear whine in 4Lo)

Yup, 4-lo whines.

Wondered about that myself when I used 4Lo--normal whine
