07 Uplander chassis clunking
 

Good Evening...I own a 07 Chevy Uplander.I just replaced sway bar links and sway bar bushings on my vehicle and the front end is tighter than it has been in a long time lol. I originally thought it was my shocks and struts but they seem to be fine.The noise seems to be originating from underneath or just behind the driver and front passenger seats or closer tobthe rear not sure, but you can really feel it on the floor while driving.My van has roughly 195,000 km on it. Not sure what could be causing it any suggestions out there? Thank you in advance for anu responses...cheers!
