What is involved in A Service
 

My 99 ML320 is due for A Service and I want to take it to my trusted indy. What exactly is addressed in A Service? What is B Service?

The truck now has 116,000 miles on it. I don't have the owners manual with me at the moment and I will certainly look for recommended service intervals when I get home. But in addition to what the manual recommends, what other items should I have inspected / replaced.

I tried the search function of this great site, but came up empty.

Thanks in advance.

Look in the back of your service book(not sure the "correct" name) , you know that little book that has the maintainance info with miles, etc... It is in detail back there, "clean cassette head", etc:D

"A" service is basically a oil change.
