Guys,
I thought I found that the sway bar bushings were causing my front end passenger clunk and popping but guess what, they weren't.
Before I drop the bomb and show what I learned through scouring the internet, I have replaced the following:
Lower Ball Joints
Passenger Upper Ball Joint
Sway Bar End Links (Had to be replaced Anyways)
Sway Bar Bushings
Front and Rear Shocks
Total bill: ~US$600
After all of that, it wasn't even the problem. There is a service bulletin that talk about this in this upcoming video.
Want to know what the clunk is? Here you go!
Remove this 7mm screw holding the small outer cowl inserts over the hinges. Close the hood.
Remove the covers carefully and don't break the clips.
The hingles will be attached and they are a 13mm nut and bolt.
That's right, a $2 dollar part fixes this problem that has pissed so many Blazer owners off.
This is the service bulletin that came out in 2001 I believe. Covers all S10 and Blazers.

Hood hinge clunk fix
TSB 01-08-63-001A
GM part # 12383460
This bulletin is being revised to add model years. Please discard Corporate
Bulletin Number 01-08-63-001A (Section 08 -- Body and Accessories).
Condition:
Some customers may comment on a rattle coming from either or both front
corners of the instrument panel near the hood hinge areas. This noise may
often be mistaken for a loose shock absorber. The rattle may be heard when
driving over rough roads and is most noticeable when the road surface
creates a side-to-side vehicle motion.
Cause:
Excessive clearance at the hood hinge attaching bolt may cause this
condition. The excessive clearance allows the hood hinge to make metal
contact with the hood hinge bracket, which produces a rattling noise.
Correction:
Important: For additional information, see the Body Front End subsection of
the Body and Accessories Section of the appropriate Service Manual.
1.. Remove the hood hinge attaching bolt (1).
2.. Install a spring washer (2) on the bolt as shown in above
illustration.
3.. Install the bolt.
Tighten
Tighten the bolt to 25 N·m (18 lb ft).

There you have it, I temporarily laid a couple bunched up shop towels under the flat part in the video and went for a drive on the roughest washboard road within 50 miles and never heard a thing.
Hope you don't go through what I went through.
