Rear Thudding noise on rear right

Hi everyone, I just bought some Cusco Lateral Links/Trailing arms and had them installed. I also did an alignment as well because I was having major positive camber. Now everytime I go over a bump I hear loud thudding on the rear passenger side. I am not sure if its the lateral links/trailing arms acting up or is this a different problem like maybe a strut? The car is not lowered, there are only a few suspension mods which are listed below:

Stock rims with 225/50/16 tires
Cobb Rear sway bar on second setting.
Whiteline rear endlinks
Cusco lateral links/trailing arms

Car is a 2004 Subaru Impreza WRX and is not lowered. I was thinking about tearing out the rear seats to figure out if a bolt or something was loose or the strut bolts themselves were loose.

Front Left: Front Right
Actual: Before: Actual: Before:
-0.4 -0.9 Camber -0.4 -0.5
3.3 2.7 Caster 2.9 3.0
0.01 -1.09 Toe 0.00 0.86
14.3 14.8 SAI 14.6 14.8
13.9 13.9 Included Angle 14.2 14.2

Rear Left:
Actual: Before: Actual: Before:
-1.0 -0.3 Camber -1.0 -0.4
0.01 2.45 Toe 0.00 -0.03

Please help if possible, thanks.

Get under the back of the car. Pound on the rear sway bar with your fist. If it replicates the same noise, it's probably your sway bar bushings that attach to the mounts. They just need replaced, or if they were new, a tighter set.
