What we would do on our trucks that went water hopping would literally tear it down, steam the entire axle housing and then spray it out with carb cleaner.
It had to do with us lunching bearing and wanting to get rid of the particles in the housing as anything.
After all was said and done, in 1997 we spent close to $1 million getting all the axles / hubs either fixed / replaced.

i know on the 3rd gen manual tranny, there are 2 breathers under the boots for the shift levers. if you have ever had to replace your shifter seat, you would see them. right there, plain as day, two breathers.
i am not sure where one would run those though. alright pretty high up considerring, and there would be a dip in the hose if you were to run them anywhere but where they are now.

what is the thread on the breathers. does anyone know?
im thinking 1/8npt by looking, but not sure.
edit:
i just went out and took out the rear breather and compared the threads to a 1/8npt nipple i have. the threads are very close, but the breather threads are rounded, which is characteristic of BSPT threads.
also when put together to see if they are the same thread, it seems they are the slightest bit different.
npt and bspt threads differ by 1 thread NPT being 27, and BSPT being 28. TPI.
anyone confirm this?

Never bothered to figure out what the threads were, I made 1/8" NPT fit. In all but one of my axles the 1/8" NPT fitting just screwed right in, in one other one I had to run a 1/8" NPT tap in a few turns. I selected 1/8" NPT because my hardware store's selection of BSP or M10x1.0 was a bit light that day (in fact I have never seen either off-the-shelf).
You can always order the Nissan or Toyota EFI hose barb fittings if you want the "correct" threads.

it is extended but not high enough. i just looked at my 96 tacoma, and it only comes up past the frame rail. easy fix though, no fittings involved, just more hose...
roger although it works, you did mess up the thread and they have the possibility of getting really messed up on you one day. it probably wont happen, but if in fact they are BSPT like i think, then you did mess them up. also they couldnt be 10mm threads because those are straight threads, and these are tapered.
british and npt threads are NOT interchangeable to everyone else, and i would suggest that someone figure out exactly what it is, or get that toyota part to get it exactly right.

VERY noob question, but here goes:
How does one check if the diff fluid looks "milkshaky"? Can you see through the open fill plug? Stick your finger in? Park on a hill?
I REALLY need to check mine...

Yep, all the above will work. General idea is to park on the level, remove plug, insert finger and feel for the proper level (just below plug level). Then check the fluid, might be able to see inside with a light or pull out some in a clear tube or syringe or whatever and look at it.
