I have a 92 I'm looking to do a basic rebuild on my transfer case just seals and gaskets (if not form a gasket) also I have Driveline clunk that goes away when my Center diff lock is engaged is this the vicious coupler that's bad if it is where can I get parts for that thanks

Normal wear on what U-joints front axle Drive Shaft or all of it I have an extra transfer case with only a hundred thousand miles on it I want to reseal it and put it in and see if that takes it away
It is the accumulated wear on all parts of the driveline that turn: Drive flange splines, CV joints, side gears, ring and pinion, U joints, drive shaft splines, transfer case gears and the same stuff on the rear.
When you lock the transfer case, then it is only the slop in one axle that has the least amount of slop, which is probably the rear.

Thanks for the info I didn't know I did not have a coupler no I don't have any other problems no leaks nothing at all just a clunk when I hit the gas goes away with Center diff lock on I know it's a 92 and famous for the Driveline clunk most say it's normal, mine seems to be worse in the extreme heat here in Phoenix after driving for awhile I'm thinking because the transfer case oil gets a little thinner and hot, anyway this weekend I'm going to pull off my front drive shaft and put the vehicle on jack stands I'll try to narrow it down some more

Have you filled your driveline yoke spines with moly grease? This and checking the transmission kickdown cable for being too tight have done the most for the ones I have worked on.

Yes I greased all my fittings at every oil change 3000 miles I adjusted my kickdown cable per Toyota manual it did help with downshift clunk but that was a few years ago I'll have to recheck it maybe I'll loosen it a couple millimeter and see if that helps, by the way I use Valvoline Synthetic Grease 0n everything, I know its a 92 but it seems like my clunk is more than normal just trying to narrow it down I'm going to rebuild my front axle in the fall I'll check my birfields then, I have no clicking from my birFields but they are original at 230, 000 miles

I would look at drive flanges first.

Yeah I'm going to do that this weekend what's the best way jack up the front end and look for rotational movement?
Don't have to jack it up unless you're fat like me and can't slide under it.
Chock the wheels, transmission in neutral, t case in high, engine off.
Grab front DS and rotate. Check to see where rotation stops. Could be in t case, flanges, or pinions.
I believe front and rear are locked together no matter what. If you lift the front tires off the ground, you will be able to turn them independently as long as the CDL is off.
