Good afternoon everyone. Just added steering component and I just wanted to know your opinion on the angles. I have 4” lift with 33s on. I have added adjustable track bar with drop bracket. Steering box and shafts. I do have stock pitman arm.(do I need drop pitman arm if I have dropped track bar bracket). I have sloppy steering and I can’t figure out what it is.

You do have a dropped trackbar mount. The best solution would be to swap for an OEM style trackbar, or an aftermarket trackbar that mounts like OEM (Currie, JKS, etc.). You could use a dropped pitman of the same height as the trackbar drop, but that’s more work than it’s worth.

That usually results in bumpsteer as opposed to sloppy steering. I suspect there’s something else in the system causing the slop.
 
Hard to say for sure... but it appears the trac bar bushing on the frame end doesn't appear to be centered. Check to see if the bushing is worn and the bolt is tight.
 
Get rid of the drop track bar bracket and keep the stock pitman arm.
 
I have been thinking of going back to Currie track bar. I haven’t done ball joints.

I have 4" of lift and 33's as well, I recently went through the front end & replaced all the steering components to solve my wandering / bumpsteer. The biggest takeaway from the advice on this board was to ditch the dropped pitman arm since I have a stock trackbar mount, and that dropped arms & trackbars don't serve much of a purpose with my lift / tire combo.

I had my wife turn the steering wheel back & forth ever so slightly on the ground while I felt around for any free play, and I eventually ended up installing the ZJ steering kit, replacing the dropped pitman arm with a stock unit, & replacing the ball joints. My steering is about 1000% better now.
 
So stock trackbars are good for a 4"lift? No bracket needed? I'm getting ready to install a 4" on my 99
