2009 W204 C200 Diff fluid change.

My car hit 70,000 km's so I though I'd do a diff fluid change.

I relied on fellow Aussie Scott Elliot's video:

He recommends Fully Synthetic GL5 75w-90. After a lot of research others were saying 75w85 I settled on this:

I found this after the fact:

https://www.sparesbox.com.au/part/penri ... -progl5001

Neither seem to have (paid for) MB approval, but GL5 is GL5 ( that's my opinion, btw, buy the OEM mercedes oil if you don'r share that opinion)

The diff needs 1.1 litre. Of course it does Mr Mercedes..so two bottles with 900 ml left over.

I don't have an air compressor so I used the bottle which has about 10-15 cm pull out tube nozzle. Eventually you won;t be able to get all of the oil in that way. I poured some of it out into a small plastic bucket and sucked about 80m x 4 in syringe and added the remainder that way.

The diff oil hat came out was thick and black

The car is now quieter, and transmission shifts are smoother. I had this problem of a rear clunk when going from accelerator to brake- the transmission would change a gear and the revs would drop, the clunk followed. The transmission doesn't behave that way, it hold the gear. Clunk gone.

That’s where those little pumps from handcream/shampoo/handwash/showergel bottles + small length of pvc tube comes in really handy - just pump it in!
Use similar to remove brake fluid from reservoir when renewing brake fluid ....

Clever tip Christo! I will remember that at the next brake fluid flush.

Checking my work shop manual it is show final oil as "Hypoid gear oil sae 90 or 83W/90.

That's what I have gone for with my Mercedes. I even rang Castrol to find out what was the right oil for my engine and manual trans plus final drive.

As long as you got gear oil in your system all is good. :rockon:
