The usual symptoms for the mode switch are hard shifting and the gear indicator lights on the dash doing crazy stuff. Doesn't sound like his problems...but you never know.

grinds worse in 4lo - used to be just in 4lo that it would grind but now its getting worse in tod mode than it ever has been - shifts fine and fluids have been drained and replaced in both diffs (rear with lsd additive) - have not drained the tcase but the fluid was never low (since ive owned it) and looks bright red - im thinking it might have something to do with the "hard drop after letting off brakes" issue that i have read about on a few archived posts but noone ever said whether or not it was fixed and what caused it to begin with
its almost a metal binding or grinding sound with the occasional pop thrown in - loud enough that i can hear it over the new muffler - maybe the cv going to the tcase? i dont know where to start...
I just skimmed through all of the posts in this thread, so forgive me if I go over something that has already been discussed.
I see in one of the posts that you got under the VX and checked the play in the front half shafts, but you didn't say (that I could see) if the CV boots were intact or not. Are/were they? How long have you had the VX and do you know if the CV boots were replaced, or not, before you bought it? The original boots are black, and would probably be a little dried out due to the age of the VX.
Do the popping and grinding sounds "feel" (sound) like they are coming from right under the front seats? Can you actually feel a grinding/vibration in the floor board under your feet?
I ask all of that because those were the same sensations that I was getting when my driver side inner CV outer race was going out. I know that's a confusing statement, but what I am ultimately talking about is what everyone calls the "green cup" on the front axle. If you get under the VX and look at the axle housing, the part that doesn't move and is bolted to the frame, you will see what looks like a big green cylinder sticking out of the axle housing. The inner CV boot should be wrapped around the end of this. That cylinder is actually the outer race for the inner CV joint. My inner CV boot split and I didn't catch it for a while until I started getting some strange grinding noises and vibrations that seemed to be coming from right under my seat when I was driving. It ended up that the green cup had gotten some junk in it and the CV joint was going bad. I think the fact that the axle is hard bolted to the frame the grinding sounds and feelings were traveling through the frame and I felt/heard them under my seat.
That's all I have for now, and I really hope that it isn't your green cup because it's a bit of an involved process to either replace it or rebuild it because it is actually the end of the drive axle that is inside the axle housing.
the cvs look good i have not changed them but they feel solid and there are no rips in the boots (they are black prob original) - the green cup seems fine too and i have no play in either axles - the only vibration comes from the steering wheel but i know it is not power steering issues because i have no leaks and when i sit still i can turn the steering wheel and there is no vibration and no sound -when you are driving it sounds like its coming from the front but if you are outside the vx is sounds like its coming from the middle or rear - maybe something wrong with the u joints or the cv that goes to the tcase? ive greased the 3 points on the driveshaft that i could - ive never had differential problems before what would those sound like?
its almost like i have two different problems going on here but they seem related - the on/off grinding and the binding of something causing the car to drop when i let off the brake after i brake hard enough (not unusually hard) it looks like the rear end has to come off to get to the rear diff to service it and the transfer case doesnt look any easier but i still dont know which one would be better to start with or if i should start with either
Have you checked the links on the rear suspension? If they have become worn out ( the joints that connect to the rear axle housing and the joints on the frame end) it could allow your axle housing to rotate (it doesn't take much) which could cause the ujoints to bind. Just thinking out loud here.
think away!!! i need all the suggestions i can get here :yesy:Quote:

anyone ever figure out what causes this? never heard of it on any other vehicleQuote:

ok is the shaft going from the front diff to the transfer case supposed to be slightly loose? i was underneath messing around the other night and i when i grab it and shake (dont laugh) it has play in it - i can move it back and forth about a quarter inch or so - i thought at first that the bolts might be loose that hold the two pieces together closesest to the tcase, but it wasnt the bolts its the entire shaft moving inside there
It has a slight fore and aft play but should have no up and down movement.
i can move it around in a circleQuote:

can anyone offer me any type of advice on working on the tcase? it seems to be one of the least talked about parts of the vx...

Would it be worth removing the front driveshaft and take it for a spin to see if it actually is the transfer case? I have the same front end noise at low speed turning( into my driveway or a parking space). Other than that I never hear it. I have not tried to tackle the issue yet. Still waiting on the rear wheel bearings to get pressed on. One issue at a time.
i drained and changed the fluid in the tcase and after about 50 miles it hasnt made the noise - i still get a clunk when i come up to a stop sometimes but the pencil shaving/ power-steering-going-out type of noise seems to be gone when i turn at low speeds - i feel stupid because i could have swore that i changed the fluid in the tcase when i did all the other fluids a month ago but i guess i just checked it - it was full and when i dipped my finger in and the fluid seemed of good color, but when i actually drained it the red was more brown than i realized - probably too soon to see if this was an actual fix, but im thinking positive - and taking out the front driveshaft is what one of the driveline specialty places said they would probably do if i brought it to them so yes i think that would narrow it down pretty good
im gettting a tick tick tick sound when i slow down to a stop and when i turn hard it grinds and almost stops the vx ..the tires churp like its in 4wd when turning... bad sounds ..i took it in to my alignment guy they replaced a rear wheel berring last month..it was leaking on the inside of the tire....sounds like mine is doing like yours
