I recently bought an XT6 from my older brother and took it to a mechanic because I have no place to work on it. He claims it has a broken drive shaft but it has been 2 months since I heard anything about parts. Does anyone know where I might be able to find one or what other models would match?

The driveshaft from the transmission to the rear diff is the same for all '85-89 4wd cars with a two piece driveshaft (and Loyales from '90-'94). The higher end turbo cars and the XT6 had a rubber dampener built into the front portion of the driveshaft but the ones without don't seem to have an issue from what I recall.

 

Now if you're referring to the axle shaft, also known as a half shaft for an axle, then those are XT6 specific for the fronts. The rears are interchangeable with all 4wd Subarus from '85-89 and Loyales from '90-'94.

 

Hope this helps.

If it's the front, here's an option: http://www.ultimatesubaru.org/forum/topic/142870-1-new-xt6-front-axle-35/
