'91 model...I'm checking into a noise in the front hub and discovered a snap ring undone. To reinstall snap ring the manual suggests special tools, eg. J-36835-2. where do I find these tools? Thanks

I'm sure St. Charles can get you special Isuzu tools http://isuzu.stcharlesauto.com/Department-Parts.aspx.

However, if it is a regular snap ring you can use snap ring pliers or two picks.
