This little fix was a lot easier than I expected and well worth it. If anyone is interested, I have a new article up on the site about it:
http://www.brian894x4.com/Shifter.html
The noise I was complaining about a few months ago in 5th gear seems to have gone away a good bit, probably because of this shifter fix, but I still have a very faint noise that's sort of a buzzing in 1st, 2nd, 3rd and 5th gears. It's prevalent under hard load, least prevalent or non-existent under no load. Sounds sort of like when you stick a card in a bicycle wheel. Not real loud, although my exhaust and tires probably drown out most of it. I'm pretty positive it's related to the tranny or T-case. Noise actually gets louder when you increase the engine load in the same gear, but not the vehicle speed. In other words, when you're on a hill and you mash down on the pedal, and you're not really increasing speed, the noise is slightly louder.
Bearing I guess? Maybe input shaft bearing? I thought they made noise all the time, when they were going bad. Any suggestions? I hate to have to pull the tranny, but I want to find the noise before any long trips next year.

Nice article- clarifying.
Didn't know about Marlin's redesigned seat either, good to know.
The only nit is, 'vein' should be 'vain'.
RE: the bearings, with well over 200K you very well could be experiencing slop. It's probably evenly distributed between the input, center, countershaft, etc. bearings. Certainly if you are going in there, you should replace all the bearings.
Marlin told me the jury is out on whether to replace synchros at the same time. If they measure well within service limits, he wouldn't - lots of customers complain about the poor shifting with new synchros until they break in. Personally, if I'm going in there, everything gets replaced (except maybe the gear needle bearings that rarely wear out).
I think a tranny ovh is well within your capabilities.

Noise is probably the counter shaft bearings, if you don't hear it in 4th gear.

So do the G series transmissions use a bushing/seat doohickey like that too? I always got the impression it wasn't replaceable, but now that I look at his website there is a "All other Toyota 4WD transmissions" option. Mostly I'm just curious because the Parts Program never seemed to show one for the G52.

Thanks guys.
The frustrating part about my tranny is that I just had it mostly rebuilt a couple of years ago after the 5th gear bearing was making a ton of noise. They supposedly replaced all the bearings and syncros and I had a new clutch put in. I do remember that with the new syncros, shifting was a bit harder than before. Sort of like breaking in a new pair of shoes.
I wish I had more clarity on exactly which bearing they did and didn't replace. Even a cheap junker bearing shouldn't be going out after only a few years and something like 20K miles.

There might be some freeplay in a bearing. Haven't had my trans apart yet, will do a tear down this Spring.
By the way, great site, lots of info in there, This will help me with my 1989 4X4.

A friend of mine had his W56 rebuilt by a very reputable major tranny shop with a good reputation who shall remain nameless. Supposedly, all bearings were replaced, etc. 50K miles later, he started having bearing noise, sloppy shifting, etc. He found out that this shop measured clearances and only replaced parts that were out of spec - if bearings seemed good, they were not replaced. He was pretty upset since he had forked over the full boat fee.
The lesson to me was,
DIY
Then I know who to blame!  
I do know that Marlin told me the center bearing retainer is an often overlooked source of shaft endplay. That's why he makes his milled version for less than $40 to replace the stamped steel one. It's detailed in the tranny ovh article I wrote in the tech section of the Wire.
