All of the repair info for ML's is on dealership computer database
that is updated by MB. The cost of repair manual sets was becoming silly at over 1500 bucks a set.
Books are becoming phased out which sucks for us since having a book in front of you is nice, and our p.c.'s are always on the fritz.

There was a 1998 new model book we all recieved way back when. It has some usefull info on the 98-99 Ml's including some
diagrams, repair, and R&R info.
the MB number is T-2678-097 and can be ordred thru your Dealer's Parts Department as literature.
The cost is somewhere around $30.00
It is 170 pages long.

Best wishes
