2008 Jeep Wrangler

Dear Doctor: I have my 2008 Jeep Wrangler serviced at the dealership. I only use the 4WD in the snow. Every year, or 12,000 miles, the service advisor recommends service on the front/rear differentials. Since I don’t use the 4WD that much, why do I have to service the differentials? Same situation with the throttle body. My Wrangler now has 25,000 miles and I spent about $1,400 in two years just to have these items serviced. Is it worth it? Sam

Dear Sam: Your Jeep requires maintenance that is listed in the manual. — Junior Damato, Motor Matters
