How much disassembly is required

Recommended Posts

Thank you nipper for your intelligent and thought provoking insight on the inner workings of a Dual Range 4x4 transmission.I clicked on the thread to see if someone had answered my question,unfortunately no it seems.

 

Does the rear tailhousing unbolt to expose the diff? or is it more of a case of splitting the transmission case and just about doing a rebuild?I'm asking right now because I don't have a subaru right now to look at.

You have to split the transaxle case - just like all other Subaru transaxles. It is not simple and the 4 speed's require a special socket as mentioned above to remove the extension housing drive gear. I don't reccomend you attempt the job unless you have an FSM and the ability to fab custom tools and equipment as most of the special tools are no longer availible and the procedures for setting the front R&P are obscure and complex besides being difficult without the special tools. The assembly procedures are a small book unto themselves in the FSM.
