Afternoon all. Want to drop the oil out of the box and change the rear diff oil before headed back to Germany in October. Think im set on what to get (DCCD box) i just need to know how much is needed for both? Thanks in advance

 

Tells you in the owners manual. It's 4.1l for box and 1.1l for rear diff.
If your Hawks a 05-06 it's uses a limited slip oil in the diff. If 07 it will take the the same gl5 spec oil as the gear box as it has a torsion type rear dif.

 

I've changed mine recently, car is an 07 and I used motul gear 300 ls for the rear diff. Is there that much of a difference?

Buy 4L for the gearbox and 1L for the diff.

 

Torsen type diff doesn't require a limited slip oil. But can't see any harm with it being in there.
If it was the other way round ie non ls oil in ls diff it would cause a problem.

Only difference being a limited slip diff needs friction modifiers in the oil to work properly, where as a torsen diff just needs a normal gear oil.

 

as above LSD oil will not cause any harm to a std diff so if in doubt use LSD oil...........

do not use in a synchro box however

 

Thanks guys! 👍
