Jimm 7/14/2012Chec k the vehicle owners and manitenance manual for the recommended service items. You may also check the website; www.manualspace.com for the manual information.
1detroit1 11/23/2012If you already haven't found out, you need to have a 100,000 mile tune up with new Iridium tip plugs, a fuel system flush, transmission flush, transfer case flush and front and rear axles flushed. Those are the most important ones. After those, then you should flush the coolant system, brake system and an engine flush. Costs will be close to a $ 1000 and you'll be good for another 100,000 miles.
Jimm 11/23/2012Keep away from the 'flushes' as a service. It's better to simply change the fluid and filter (if equipped) for each of the systems listed. There is no reason to shell out nearly $1000.00 for these services - if done properly.
