super subbie Posted July 8, 2022 Share Posted July 8, 2022 I have a mysterious vibration problem; hoping the gurus can help. This is a 95 outback, with a 90 EJ22 in it. The tranny locked up in reverse, so I replaced it with a 93. (That might be the problem right there, but this is a FrankenSubbie for the teenagers to drive to school). The new tranny ran fine for about 20 miles. Suddenly the whole drive train seems to vibrate. Driving straight on pavement. I pull over to the shoulder, wait a while, and it's fine. This has happened repeatedly, forcing me to drive home at 5mph. I park the car overnight, and then it runs fine. The vibrations are severe. Very alarming at high speed. It feels like the whole drive train is binding or fighting against itself. And I noticed if I go over a speed bump, or otherwise unweight one of the wheels, I can hear it make a little screetch or skidding sound. I assume it's a bad center diff, but this happens when driving in a straight line. This is undoubtedly a severe mechanical interference problem, but it goes away if I park the car over night. That's the part that perplexes me. Any advise is appreciated. Quote Link to comment Share on other sites More sharing options...
