Hi everyone
I would say when you are doing it yourself there are a number of things to check for.
Like mentioned before, if you are doing the brakes made sure for a well branded one, also while you are back there you can adjust your handbrake and bleed your brakes with new brake fluid if it is older than 2 years.
When the wheels are off make sure at the back that links ( 5 of them )at the rear wheels are in good conditions, they tend to perish were they have rubber joints and causes misalignment.
Do your fuel filter and check the rubber house that leads from the fuel tank, it tends to go bad after a few years.
Check your drive shaft rubber doughnut at the diff. and at the end of the gearbox. They also tend to wear.
Check diff oil level, oil seal tend to leak were drive shaft comes in.
As mentioned, if needed do gearbox oil and filter.
Do oil filter and oil, if your car has high mileage get an oil that is sold for high mileage cars (shell is good).
Do air filter, (the filters are normally cheaper at the dealers but check it out first).
Pollen filter is a good idea for the air-conditioning unit.
Grease the wiper motor and the internals; they tend to need grease every now and again.
When front wheels are off check the rubber bushes of the suspension (where you set the wheel alignment)
Check the power steering oil, is clean and filled up.
Make sure the right spark plugs purchased. (Sometimes they are cheaper at dealer)
Flush the coolant if not done in the last 2 years and fill up with clean water and add Mercedes Benz antifreeze and corrosion inhibitor. MB part no 0009890925. This helps to resist corrosion-erosion.
Check the battery water and fill up with battery water if necessary.
Do Fan belt if the belt shows any aging (Creaking)
Check tire wear and if necessary do alignment (this saves money if you do it ones a year but also depends on what roads you are driving and your driving stile)
