Always check the capacity of the rear axle for your car and the best method is filling up on a ground level and filling until the fluid starts dripping out of fill plug.

[@tramptruck4859]

Often neglected but very important 😊

[@BenzAddiction]

Yes, even many mechanics check the rear axle for leaks and if dry, they leave it alone.

Great video! Just a heads up, the CLK 55 AMG has a slightly different differential design but still uses 14mm hex for the drain bolts so everything here in this video will work for the AMG too. The fuel filter however, if your CLK was made on or after 2004 it's possible that you will not see your filter in the same location as in this video. That's because Mercedes switched the fuel filter/fuel pump design to sit directly inside the fuel tank via a dual pump design which is both good and bad. Those later designed fuel filter/pump systems lasted longer and were more reliable but are much more expensive to replace.

[@BenzAddiction]

Great info, it is more difficult to replace the internal filter and pump as well. The car in the video is a 2004 MY05, my 2003 CLK500 had the internal pump and filter.

Thanks mate, not to be forgotten.
All oil, fluids should be changed at regular intervals to ensure proper mechanical functionality.

[@BenzAddiction]

Very true👍

[@Leonardo555ZZZ]

Over the years , the oil level also declines due to vapour losses out the breather. This then accelerates the oil quality decline and can lead to problems if never drained and filled with new oil.
I changed mine a year ago , 2005 CLK using 1.3 litres of Castrol Syntrax Universal Plus 75w-90 Fully Synthetic. MB Spec. 235.8
I filled it until it just starts to overflow ,,
using a manual pump from a bottle.
I put a small amount of silastic gasket maker on the threads of the plugs.
Car should be level ,ie raised at the front as well as the rear if working off the floor with jacks.
Well done Max, good advice.

Thanks for great tips Leonardo 👍

Thanks mate 😀

Simply, you are one of the BEST, noooo doubt..

[@BenzAddiction]

Thanks mate for your kindness 👍

You should everytime open first the fill plug, because if its not gonna open and you already dried it, you have a big problem.
And you should put so much oil in, until something come out from the fill plug

[@BenzAddiction]

[@allanriches9381]

that is one very important piece of maintenance , also power steering fluid is another missed maintenance item.

[@BenzAddiction]

Yes, as important as transmission, it can set Benz Owners back by $3000.

Thanking you 👍💯

The same exact fluid I used for my 2003 W211 😊

[@BenzAddiction]

Yes, not many rear axle fluid available in the market.

[@73SDR]

You poured yourself a shot of old and new, but didn't say which tasted better!

[@BenzAddiction]

Old is gold

[@brianhuh6170]

I don’t think you filled enough fluid. You should fill it and wait until the fluid drops to a last drop then that is the right amount.

[@BenzAddiction]

Well, do you think if you open the fill plug, any fluid will drip out? Also there is another risks on these cars, the 3 seals should not get over excited by overfilling at this stage, or they might start leaking...

[@brianhuh6170]

@@BenzAddiction when you open the fill plug, if any fluid come out then you filled too much. Also if no dripping that’s when you filled low.
Since it don’t have a dipstick, the car must be park in ground level position. You fill the fluid and just wait until only a few drops dripping and that is a correct fluid level. But only a few or little more fluid should be okay.
After fluid changes, my car got so much quieter than before. Good fix for under $20 diy

[@jamesclark7248]

Are later spec fluids backward compatible with the older specs?

[@BenzAddiction]

Very good question, I always want to see the spec on the container otherwise l wouldn't trust this theory.

[@harnas3848]

Have you reused the old plugs ?

[@BenzAddiction]

Yes

[@benpasquale6353]

i use the penrite 80w90 because its not LSD
