john in KY Posted February 26, 2018 Share Posted February 26, 2018 (edited) May need a rear driveshaft for a 1990 Legacy. Will one from a newer year interchange? Seems I read somewhere once that there is a difference in the very early Legacys and newer models. Something about the rear U-joint being different. TIA.

3Pin Posted February 27, 2018 Share Posted February 27, 2018 I see you have answer, but in the future, you can use car-part for parts compatability. They are pretty good. Quote Link to comment Share on other sites More sharing options...
john in KY Posted February 28, 2018 Author Share Posted February 28, 2018 Actually did check that site. Just didn't want to believe 90 and 91s only. Why won't a newer one work and then I recalled reading something about the rear yoke being changed or something. So decide to just ask the experts. In the process of buying a 1990 legacy with a bad driveshaft. Looks like if the deal goes through will have to take it to a machine shop for a new joint. And on my 95 several years ago I tried to remove its joint and it was a failure. Even a sledge hammer couldn't move it. Quote Link to comment Share on other sites More sharing options...

Use a brake cylinder hone to clear out the remnants of the u-joint stakes. Install new U-joint with internal retainer clips. Quote Link to comment Share on other sites More sharing options...
