Moog or TRW , I wouldn't use anything else.
Are they worth it ? , yup , they last waaaayyyy longer than the cheapo parts.
Same thing with unit bearings , SKF only
I used to be a fleet mechanic / manager , the trucks we owned and serviced were driven hard in adverse conditions , some of them chained up for months at a time . Moogs ball joints only on those trucks , nothing else would last.
