It seems that my 96 Legacy OB is suffering from torque binding whn going around tight turns. It only does this after 15-20 minutes of driving. After everything cools down again it won't do it anymore.

 

Is there a way to check the fluid level in the viscous coupler? If so where are the drain and fill plugs? Finally, what is the recommeded fluid to be used in the viscous coupler?

 

Thanks for the help!!

Ptrbilt -- The VCU is sealed and cannot be refilled (it contains a special silicone fluid); it must be replaced if it fails. There's an article at http://www.autospeed.com/cms/article.html?&A=0920 that says pre-'99's have a cartridge that can be replaced, rather than the whole unit; you'd probably need to find a dealer service/parts dept. that's willing to share information to find out if that's available. 1stsubaru.com is pretty good. -- George
