Diff oil change

[DocArbathnot]

Hi I don't have a pump to refill the diff. I've an old eezibleed kit do you think I'll be okay with this?

Bit more info needed
What diff
Why are you refilling
Access to filler hole
Most just use the squeeze bottle

Merc SL 129 14mm hex key 1.25l

I've not climbed under the car yet to look @ the access. Some online notes suggested a pump, I like to have everything ready to avoid wasted time so thought of the spare eezibleed thingy to pump the new oil up.

Can't SE why that would not work

[DocArbathnot]

I think it will be okay, using just my lungs I can move the oil.
The car has always been main dealer serviced. I doubt the diff oil has ever been changed, so 19yrs and 100,000 miles I thought it may be a good idea.

No the eezibleed thing is a bottle that you pressurize from a spare tyre. I tried it with lung power just to make sure it worked. The only thing is the bottle is only about 3-400ml so will take a few refills.

Make sure you can undo the fill up bolt before you drain the diff... Also, i tend to use a funnel in some garden hose and let gravity do the work. Lastly, make sure you have a new seal ( normally a copper washer ). PS Nice car!

Just buy the 500ml pump :S

I can't speak for Mercedes but I work for Lexus and diff oil is changed every other service, so every 2 years or 20k miles.

Check the service items and take it from there would be my advice
