I just purchased a case of Schaeffer's #238 moly grease. After using it to lubricate the suspension of my vehicle I found a article on compatibility of greases. It stated that aluminum complex type greases are borderline at best in compatibility with lithium complex based moly greases which is what I had previously used to lube this vehicle. I don't want to over service the ball joints to flush out the old grease in fear of blowing out the boots. What do I do now?
