When I am driving my 99' S-10 Blazer LS there is a "poping" noise comming from the front end when I deaccelerate and turn at slow speeds (especially when I back out of my driveway and am turning). I have changed half-shafts on both sides and have had the lower bushings replaced (mechanic said the uppers were fine for another year). The hub on the passenger side was changed a year ago and the driver side is still good. This is starting to get expensive with all of the other upkeep on my 3 other vehicals. Any ideas?

 

my guess would be ball joints.

 

i would agree with ball joints, and maybe a sub frame shift, tighten everything down and see what happens. Also check to see if you spring is seated well it the shock assembly. My cobra used to pop when i braked or accelerated hard, and it was the spring not sitting straight in its pocket. Good luck.

 

Loose caliper bolts?
Worn ball joints?
Broken link pin on the swaybar?
Worn c/v joint?

 

My vote would be for balljoints as well. As a temporary check, try greasing the front end and see if the noise goes away. If it does, then you've got a problem in one of the joints that you greased. If you really wanted to narrow it down, grease one thing at a time and go for a drive.
