Help me diagnose this

[Black92LX]

This only happens when I am starting from a complete stop.
If I accelerate at normal driving speeds I have no problems.
Though if I give it a lot of gas and try to accelerate quickly or slam the throttle from a stop. I feel my back end start to buck quite severely.
Or if I give it moderate gas and I am on a heavy incline.

It does not do it if you are already moving and slam the gas it is just fine.

Feels kind of like the Auto 4x4 is kicking in, but I don't think I should be feeling it in the fashion that it is.

I have been meaning to do the brown wire mod and see if the problem is still there when in 2wd mode.

Any thoughts??????

Should I really be feeling it that much??
My tires have less than 2,000 miles on them.
Should I put new fluids in (i have 76,000 miles bought it with 74,500) and don't know when they were last changed.

Brown wire mod is looking very very good.

Check the pressure in all 4 tires. Adjust them to match what's recommended on the driver's door tag. See if that helps.
