Republicans don't want to remove the filibuster because they want to keep it as a tool when they're in the minority and use it to blame Dems for not doing things while in the majority. Fundamentally, Republicans just want tax breaks and judicial appointments, and the filibuster already doesn't block those. So it hasn't really been a problem for them. Since Dems in theory want the government to work, they can keep things working well enough to let the Dems deal with their time bombs like expiring ACA subsidies and middle class tax breaks.
