Look up Dexta on eBay. They have a rebuild kit @ $81. I bought mine at a dealer out in Missiouri. Includes a top shaft and race/bearings and side seals. Replace and rebuild top, and remove left arm, then the housing. Replace side seals. Removal of shims tightens and takes out play. Figure that out and put it back together. My issue came that when you replace the left housing it needs a gasket or RTV to seal.
This one is perfect now. Like new. No play, no leaks, can't lift the steering wheel and feel play. Did I mention clearly, ...no leaks.'
