2017 GLS550 142k Service

Stuff to remember when it's time for the next oil change:
- Should order rear brake pads
- Should replace at least passenger side exhaust cam position sensor due to oil intrusion evidence
- Consider pulling rear plastic underbelly stuff to fluid-film coat

Ordered the oil filter, cam sensors (2), and rear pads today. Still need to get oil.

Got the oil, but high speed braking shudder now has me believing I need to replace front rotors. How do I figure out whether I have the sport braking package or not?

I'm also curious what Benz OEM rotors would go for, as other parts have been at least semi-reasonable.

[rpaoness]

Looks like $205 ea for OEM rotors. For at least one model. Appears to be two listings for front left, and then a note to only replace in pairs... kinda weird. $258 for the other.

Compare to FCP Euro.

How do figure out sport or not sport brakes?

[kevm14]

I would assume you have the up level brakes because 550 but the fool proof way is for me to put your VIN into EPC and see what the p/n is then cross reference as needed.

[rpaoness]

The Benz parts website and Rockauto both showed two numbers for the 550

Compare to FCP Euro.

That thing I said.
