Transfer case

[Metalcheese100]

Howdy!

I just purchased a 00' LX 470 last weekend. Rust free, great maintenence records and no accidents. With that said, I drove it home and to my mechanic to have them inspect it and he mentioned a possible transfer case issue.

When shifting the gears a small noise is made. He recommended I take it to a transmission shop to let them look over it and get a better idea. He said no 4x4 fun until then. I don't see a lot of transfer case issues here so I wanted to get an idea of what to ask about. I found quite a few online from $350-600 should the need arise. The only other concern of mine personally is the AHC. The records showed it was topped off but never flushed and replaced. The prior owner (it is a 1 owner vehicle) never used it and didn't know what I was talking about.

I can attach a video in a bit if that would help with the clicking/shifting noise.

Appreciate any guidance.

Take the video. There can sometimes be a slight grinding noise that will come from the t-case while the gears are meshing properly during shifting, but there shouldn’t be any prolonged noises

I did it a few times so you could hear it. This is from R to D. The noise does not stay. It just makes it when the gear is changed and then stops.

Usually this is worn CV axles/drive flanges (on the front axle).

Agree. Sounds like a combination of front diff bushing and worn CV/drive flange.

Should easy to check both.

If this is a noise when moving the transmission shifter from Drive to Reverse (or vice versa) then I would suspect drive-line issues, as already mentioned by others.

If you think the noise is related to moving the transfer shifter, then skimming the experiences at the following thread may help:

On AHC, the following are good starting points -- provided by @LndXrsr and @suprarx7nut:

When you get to bleeding the AHC system, the process often goes smoothly. However, it is good to be aware that there have been many experiences reported in IH8MUD threads when air in the AHC/TEMS systems has been reluctant to leave, and the ride quality afterwards was very disappointing -- most often resolved eventually by multilple cycles of all of the bleeding steps to purge trapped air.

as long as the transfer case has oil in it, they are fairly bullet proof.

as stated above, look elsewhere

HI, my 96 fzj80 does the exactly same noise from R to D and vice versa

Did you fix yours yet?

Not yet. Haven't found a shop I want to use. Im planning on doing it next month.
