Should I have shop redo this alignment?
2015 e400 w212 4matic sedan. Staggered tires. My old rear tires had really bad uneven wear on the inside edge. A brand new tire was destroyed in 5k miles. I had it aligned and put new expensive continentals on it.
These are the results from my alignment. The rear toe is barely changed and the wheels are still noticeably at an angle. Should I have the shop correct this alignment or is it good the way it is?
I paid $1200 for these tires I dont want them to be destroyed in 5k miles.




My view on having an alignment done is I would only have the MB dealer do it. From reading thru the manual it looks like they are supposed to check the level of the car first, if out of tolerance then inspect/replace springs, bushings or whatever the issue is. Then they can measure the alignment of the wheels.
Appears on the rear only the toe is adjustable by turning the cam bolt. Does a local wheel shop do this? Tire shop down the street from me cant even torque wheel bolts properly.
I looked thru the alignment specs for 2015 W212. I didnt see a 4matic 485 with front/rear steel spring, found a 4matic 485 front steel and rear air spec. I dont really understand the what the numbers mean though.

We are all in that same boat with this setup.
> FRONT END :
The rubbers bushings are now too soft
The SB links make the chassis bouncy
The ball joints are loose
The dry strut bearings are no longer centering
The front wheels bearings are loose
The tie rods: not too bad!!
> REAR END:
The rear multi link setup has 5x arms to replace
> SHORTCUT :
FCP Euro sells suspension parts KITS for this purpose.

The front got new control arms and tie rods. I didnt do any work on the rear.




The rear toe is set by a combination of links... not as simple as front end tie-rods.
When rear springs sag all angles go out of range.

Front- toe, camber and caster are adjustable. I believe special bolts are needed to make adjustments.
I would inspect the entire suspension for anything worn, loose or cracked bushings. My tie rods look pretty bad so I have replacements i just need the time to install everything. It involves lowering the front of the rear subframe to remove the bolts.

There not super expensive to buy.
Do i need another alignment after replacing the rear springs? In theory it should just straighten out the rear camber without effecting toe right?
Then do a toe-in realignment
I would try that approach first

I can recognize my rear camber is starting to mess up the rear toe. I have not done much to this growing issue.
@pierrejoliat has delt with this by installing new rear springs.
@S-Prihadi Used a set of adjustable arms for more range.
You can use one or both options combined...
Much needed adjustable arms are not luxury items to align the rear end where it should be.
Any time you affect geometry with new parts: an alignment is best to adjust angles back to specs.
You can tell angles are fairly precise.




Safest with PROPER spring compressor.
But some can do it with jacks only.

Do becareful yah. The spring is 500+ kg of force.
Alignment at the REAR is only for rear toe, yes you need to do it after spring replacement, just to be sure.
==============
For my case, new springs did not cure the too much camber at RIGHT REAR.

I had to use adjustable rear camber arms, right side only to get back to proper spec

But do remember, my camber is not crazy out of whack, but is not within SUPERB spec.
I have no issue of rear tire weird wear.... I won't allow such thing to happen.
Have fun................
