What does it take to convert All wheel drive to regular 2x4, 4x4

[Blackbox19]

Got a 1997 V8 All wheel drive. I hate the vibrations coming from on road 4x4 all the time. What does it take to convert over? The truck has been in family since new and only has 41k miles on it so not getting rid of it. Has every option that could be put on one too.
I read a bunch of 3 or so year old post about this. But want to know if any resent info out there. Thanks.

do a search on 4406 swap. thats about the only way you can do it.

I inherited the truck from my great aunt so Dont want to sell it. But dont want just a 2x4 either. I wanted it to have ability to be a 4x4 also. I live down deep south so no snow here. I thought the awd case was same lenght as the 4x4 version. that way I could just drop this one and install the other. I can figure out the mechizum to get it to shift into 4x4. just dont know what case bolts to the V8 trans.

 

[Blackbox19]

What auto trans do I have? Is it same as the V6 model?

Not the same, you probably have a 4R70W.

Did they ever make a part time case behind my engine and trans combo?

You don't have vibrations because of the AWD. AWD is NOT just a 4x4, it is a different animal (AWD=central differential with limited slip via viscous coupler VS 4x4= rigid coupling of the axles via friction packs), there is no comparation. I have an AWD and there are no vibrations on highway.

Balance your tires first.

Its not the tires. When I take curves or get on it hard it vibrates. And there is a pretty loud roar from what I can tell is in the driveline.
I can get on it a little and let coast and dont have any noise or vibrations.

 

[Blackbox19]

The roar is really aggravating to me. I assumed thats how the AWD works. Cause I never had one and this one has so low of miles on it. I did not think any thing could be going bad. All fluids have been checked and are good.

The vibration is not happening at WOT. Its when I take off. Like the rear drive shaft is out of phase.

 

[Blackbox19]

I tried to take a picture of the front drive shaft. Its not a double carden type. Its a CV type, with what looks like oil coming from it. Could that be my problem?
Here is some pics. Not the best as its hard to get under there.

 

[SoNic67]

Did you check the fluid levels on the TC and front diff? They have access holes for that.

 

[Blackbox19]

Yes, I posted that earlier. All fluids are perfect,.
That CV joint leaking has me thinking that may be my stick in the mud issue.
Only 129 bucks to replace. But dont want to just throw parts at it.

 

[Blackbox19]

Just went out and really got under there and looked. Nothing is leaking that I can tell but that CV joint. The fluid in it is thick and reddish. Dont have a pronounced smell.
There is no movement in the joint so how do I tell it it needs replacement? The boot looks fine on it. Looks like the fluid is coming out around the circumference of the outer shell of the CV.

I'm no expert but:
1. Have you checked the front and rear tires have the same diameter? I mean measure it because different diameter would force them to slip as they turn at different speeds.
2. If you have strong grinding sounds, check the wheel bearings. They could also cause vibrations
