Need help quick

Good evening my cars up for sale and since things are as usual not working right.
Basically I changed my wheel bearing and everything went back in the right place abs and auto handbrake don't work.
I thought I'd change my abs sensor on that wheel incase it got damaged during the change and since then this morning it's making a horrible clunking noise once turned on and first used after that it goes away

Car is currently up for sale new vehicle comes sat I need this fixed asap. Anybody near me can scan or help diagnose please do thank you very much
