The Rehnquist court made rulings that allowed burning the US flag, that made abortion even easier to get than under Roe, that upheld affirmative action, that struck down sodomy laws, and that ruled that political speech was not protected by the First Amendment.
The main conservative rulings it made were minor restrictions on the commerce clause.
Conservatism in the judicial branch began with the confirmation of Ed Meese as US Attorney General during Reagan's second term.

On the other hand, movement conservatism is anathema as well. Free trade is out, state's rights abandoned, except maybe as the exception that proves the rule, governmental power concentrated in Trump personally, rather than small, local government, representative democracy, lower taxes, less regulation, rule of law. Freedom of speech reduced to conservative speech getting special treatment. All also gone. Weird.
