Toe out causes inner wear... And if you have a decent amount of camber it's a double whammy
Odd... just changed to my winter set up and found this exact same thing on my front right inner PSS. Although did manage to get 25k miles on fronts... wear not at wear bar yet...
Cheapest and helps it but doesn’t fix it is replace control arm and thrust arm bolts with Mercedes slotted fixed adjustment bolts as mentioned above. Can do one on each side camber only but doing the caster one affects camber too.
Other options are expensive but so are tires. Kmac bushing replacement or upper control arm replacement with adjustable ones allow you to dial camber in to whatever you want. Not without debates on drama though as you will read. Some say squeaky, some say they wear out quickly.
But as a manufacturer proudly this “ ongoing development” we find is a whole lot better than merely watching, doing nothing flawlessly.
What we have achieved is filling a need providing Camber and Caster adjuster kits - Audi through to Volvo with over 800 P/N's involved. Always meeting / resolving along the way the challenges of creating fail safe long term durability (See Web Site www.k-mac.com ABOUT US).
W204 / AMG OEM full front & rear wheel alignment is only Toe (directional) adjustment !
No “ongoing” Camber or Caster facility allowing to change tire contact angles. Essential to cater for uneven tire wear, the result of high cambered roads, altered height through lowering or load carrying, fitting wide profile tires, worn bushings or simply curb knock damage and / or correctly resolving steering pull, Track Days adjustment to increase track width and reduce understeer or oversteer .
K-MAC adjusters replace the four FRONT highest wearing bushings – and are Camber and Caster adjustable, Mono ball / 2 axis design also improving brake and steering response. P/N 502616 K $480
Also replacement upper Strut mounts for coil spring models ( additional Camber & Caster for track days ).
Stage 2 (Street / Race) P/N 503016-2L $545
Stage 3 (Full Race) P/N 503016-3L $545
REAR – Camber ( and extra Toe) adjustable P/N 502226 K $480
NOTE : Both the Front & Rear unique K-MAC patented design kits allow “precise single wrench” adjustment accurately (under load) direct on alignment rack !
Also for REAR uprated bushings for the “6 multi link arms” – less rear end twitch / flex / loss of traction – especially when applying power to lane change / overtake P/N 502628 K $ 480.
