Anyone change door inner lock before ?

Ive change :-
Door check
Door inner and outer moulding
Glass channel run rubber
Door rubber

Contemplating of changing the inner door lock too but its kind of pricey (Around Rm500), Wanted to make the door close like when its new.
After change the above can feel the road and external noise is reduce by quite a lot, closing door is more solid but still lacking the thud sound.
