Girl with wrenches
My 97 2wd s10 has had a vibration and loud humming comming from the driveline or rear end somewhere and it's quickly getting worse. When it's jacked up and put into drive I can't hear anything. Tried to search the forums and mostly just found u joint issues. Just pulled out the driveshaft out to check the u joints. They seem to move smoothly and there's no play in any of them but the rear double cardan seems to move kind of choppy though. Really not sure how to check double cardan joints. How do I check them? The carrier bearing seems fine too, moves smoothly. Other then that anything else I should look into that could cause the vibration and sounds?
