What does this mean? Or what could it elude to? It sounds like a smaller beehive is in my gearbox while in 4LO lol.

Lol well I assume this is not normal? Or is there always such a degree of noise that emanates from the shifter area?Only way to find the queen is open up the hive. Aka - transfer case needs to be opened up and inspected
Ill give that a shot tonight! Thanks OSS 👍If you lightly press on the transfer shift lever when it’s making that noise while driving and the noise goes away, then maybe it’s just the shifter linkage rattling. There’s a rubber bushing or two in the linkage. Maybe it dissolved.
The LC is noisy. It is what it is. It's not a luxury vehicle. It's a land cruiser.
lolIt was considered luxury at the time. Even advertised as a step up in luxury.
Ok so I tried what you suggested, but nothing changed. However, the "Buzzing" sound completely goes away when I take my foot off the gas. If I lightly apply the gas, the "buzzing" is lighter. So basically the more/less pressure I take off of the gas makes the buzzing louder/quieter to non-existent if I take my foot off entirely.If you lightly press on the transfer shift lever when it’s making that noise while driving and the noise goes away, then maybe it’s just the shifter linkage rattling.

Probably a combo of everything wearing out.I bet the Outputshaft bearings are toast. Around 150k they start to get loose.
My 60 was at 300k and way overdue.
No, I didnt record any audio, so you didnt miss anything.Is there an actual audio I missed?
It doesnt sound like a rubbing sound, at least to me. I guess you could describe it the "buzzing" sound, potentially, as a "vibrating" sound, sure. The sound changes depending on whether or not I am pressing on the accelerator. If I relase my foot from the gas peddle entirely, the sound completely goes away. If I apply pressure the sound can resume, and then build up more and more, depending on how much pressure I am applying.Can you relate the noise back to something mechanical? does it sound like rubbing or vibration (ringing). Does the sound change (in pitch or timing) based on engine rpm and/or overall speed?
do you know you are really in 4wd? Is this the sound of the gears touching but not meshing? What is your evidence you are actually engaged in 4wd?
Have you tried how different scenarios effect the noise (wheel hubs locked, wheel hubs unlocked, transmission in neutral or not, transfer case in neutral (you need to be stopped when you switch between transfer case 4H, N and 4L)? For example, locking the wheel hubs but transfer in 2wd will have the front wheels spin the front differential and drive shaft. When I do this, I can definitely hear the front differential hum.
The sound is present in 2h as well, just to a lesser degree. And again the "buzzing" completely goes away when I take my foot entirely off of the gas peddle.Lots of possibilities here but since the sound is present in 4hi and low but not in 2hi assume 4wd related: front driveshaft joints, front diff, or t/c front output bearing. Definitely check fluid but you’d probably hear it in 2wd as well if dry.
