Front suspension noises and ride height

[Snakes709]

Hey all, awhile back I removed the lift kit off my at4 and lowered it originally 2” and then later another 2” using bilstein 5100 on all 4 corners, belltech lowering shackles in the rear and belltech drop spindles in the front. All was fine for quite awhile until after i did a time attack event at the track 

 

 

I then started hearing light clunking noises on the right front and now im hearing alot more on the left front when going over bumps. I also noticed my right front sits about 1/2 to almost an 1” lower then the left front. I searched high and low for issues, took the wheels off, jacked up the suspension so it would be at normal height and i cant see anything visually or hear anything when i try and shake things. I am guessing one or both of the bilstein struts are blown. Wanna get your guys thoughts on the matter before i take it in and get it diagnosed. I wanna replace things myself but before i throw money at parts, i wanna know what parts i need. Either way i was thinking about going to belltech adjustable coilovers.

CV axle fitment issues?  You bought a lifted truck from the factory that has different axles, then lowered it without swapping to the axles that come on non-AT4/Trail Boss trucks.
