Passenger side CV joint had been clicking for awhile so I decided to replace it. Found the part at O'Reilly's got my old one out and... wrong part from O'Reilly's. Texted with Cole (CaveVan owner) on this forum and he recommended a re-builder out of Denver, CVJ Axle (303-297-2448). They did fantastic work, sent me a rebuilt unit that installed perfectly. Thanks Cole and CVJ!
