transfer case problem?

Ok my 79 cj7 I got about 4 months ago. Finally driving it around after getting some new swamper shoes for it.
Not going far from home yet. Still fixing little things...

Yesterday I thought I would try out the 4 wheel drive.. Got out locked the hubs.
Then put in 4 low... Sounds like something is broke after I steped on the gas. It worked before. Its works in 2wd fine.. and it sounds like broken gears or some thing. Drive shaft is turning.

I then unlocked the hubs and left in 4wd still sounds horible. Put it in 2wd and all is good.

This jeep had a 304 from factory. It had a 6 put in somewere along its life along with the 5 speed and transfer from the 6 cylinder swap.. It now has the 304 in front of the 5 speed.
So I know the transfer case is a big iron unit, I believe a 200 hundred.

So my question is were to go from here. Maybe take the front dif cover off and take a look first? Just to make shure its not the front end. I will do this tonight.
Can I rebuild that Transfercase myself? Is there any good sugestions for this T case... Also if im going in there Can I lower the gears?

Take the diff cover off, and check it out. It probably needs new oil anyways. If the gears look good, also check for a broken axleshaft before blaming the Tcase. The 300 is nearly indestructible, but the Dana 30 is not.

In another week or so, I'm going to have an extra set of Dana 300 internal's. So if you need any Dana 300 stock gears, let me know.

I am putting in LowMax gears from JB Conversions. But my case was cracked so I had to buy another t-case to have a case to work with. I have stock gears for D300's coming out my ears now.
