A few odd 4WD questions.

Is it normal for the gears and transmission to feel stiff after being in 4WD for a while. Stiff is the only word I can use to describe it. Everything seems to work fine. As soon as I drop out of 4WD it is all back to normal.

While I'm no expert on the subject, I would think you're increasing the pressure and resistance on the entire drivetrain every time you engage the front axle, especially if you're on hard-packed earth that doesn't allow a huge amount of slippage. All that extra torque and friction is bound to be effecting the way the gears and such work together--that's why it's so important to never keep the 4WD engaged on dry pavement, as the binding can increase to the point of breakage.

according to Toyota you can drive in 4Hi on dry pavement as much as you want.

You mean it doesn't shift as easy?
 
I wish this forum had ******* tokens or credits. That way if you ever want to destroy someone in one post without being censored or warned/temp banned/banned, you can just use a credit.

I don't think I would have a stockpile of credits though...

Wrong. So very horribly drastically catastrophically wrong. Part time 4wd rigs should never use 4wd on a high traction surface at any speed.

According to Toyota that is you who is wrong even though I personally agree with you, no point on driving on highway with 4WD engaged, unless it`s wet icy or snowy, there is only one problem there... it migh be too late to engage 4WD on slippery surface.

What year do you own? The later models with the center diff are fine, as they differentiate between the axles. The older ones with the fixed 50/50 split are typically not recommended for dry pavement use.

In his sig line it says he has a 91, which would be a part-time system.
And we all know a part-time system shouldn't be driven on a hard surface in 4WD, especially in Low range. The drive line will bind up, causing several symptoms. 'Stiffness' could be a description of it, but until the OP responds w/more info, it's all guessing.
 
Nope, took it out of 4wd the moment I got off the tough trails. I never run 4wd on pavement as there is no need.

Let me try and explain it differently. Normally you can give it a little a gas and move off that gas for o moment. In my case I give it a little gas and it feels like the brake is slightly pressed and I am driving through that. This is only after being in 4wd for a while.

I was making that comment to Victor Inox, friend--there is no sig line for him/her. I know Bill drives a 2nd Gen with the part-time system, but I don't know what model Victor is speaking of.

Which is the point I'm making--the later models like yours have a center diff which can vary the power between the front and rear axles, something the older part-time (50/50 split all the time) transfer cases can't do. You're comparing apples to oranges, friend.

That makes sense if you're turning. If it feels this way going straight, too, it must be a little lingering bind in the T-case. Is there ever a problem shifting back to 2WD? If not, and you're doing all your wheeling off pavement, I wouldn't worry about it.
 
Anyone know what year or trim they started using a center diff?

I know all 96+ t4r's have a center diff, but what about 90-95's?I still have all vowels and 1 cons

While I've never researched it, I've had a 94 and two 95's, and none of them had a center diff. If you know the 96's had them, then that's probably when they started.
