the answer is what not to put into the diff. In the instructions will be the oil list of oils that can be used, ,,one that is recommended by wavetrac,, is Motul,, guess who carries Motul,,= NEEDSWINGS,, in fact (Needswings) carries all the oils that wavetrac recommends ,,

one thing i was told today is not to put a petroleum base oil in your diff.

if you send your diff. to wavetrac, and want them to install the wavetrac into your diff, here is what they will do,, replace the seals (not the bearings) ((Mercedes bearings are one of the best and most do not need replacing))((( the cost of just the bearing for our diff. is around $400.00))

My personal opinion is that you,All of you, that ordered the wavetrac,,send it to Devin at Wavetrac for them to install the unit into you diff, two reasons for this they know our diff and will have done a few before yours gets there. read Mike R,, "i got a good laugh today" it is on this page three post above, if the good old boys down at the gas station does your diff . and it failed for any reason, are you covered,, wavetrac knows we are useing this diff(wavetrac) for racing, they made it for that ,but if your ring and pinion are not set up correctly,, you will say &^&*^%^&^%&^&^%^&^ ,, so be safe in the beginning and injoy you new found rear(diff.). jim
