1993 7.3 IDI turbo. When I replaced the vacuum pump because of low brakes, squeaking started. So far I've installed two different new vacuum pumps, cleaned/regreased both idler pulleys, installed two new idler pulleys, greased the idler pully spring arm. Still this dang noise. By the way, brake issue fixed with new vacuum booster. How do I attach a video? What's the video size limit?
