Having problems with your 2002 Toyota 4Runner ?
Transfer Case gear oil change
\015 Is any transfer case gear oil good enough? I used a high quality Belray 80W gear oil which seems to doing better than 75W manufacturer's recommendations. How often should it be changed?\015
If you use the vehicle for towing or drive in very cold conditions you should do it every 30K miles. Ordinarily you should change it every 60K miles. If I recall this is what Toyota recommends. I personally would recommend doing it every 30k. The Belray is good so I would stick with it .
