The front tires are wearing on the inside shoulder due to negative camber on the front. All other alignment specs are good. There appears to be no built in adjustment on this model. There are aftermarket cam bolts that are supposed to be used in the struts, but do not fit this model, although parts are listed to fit. Does anyone have a solution to reduce the negative camber on this vehicle?
Have you had any work done to raise or lower the vehicle? What shape are the struts in? What about accidents ? What is the camber set to now? Did you look into aftermarket camber plates?
Testimonial: "No work has been done on the vehicle. The struts are like new, only 17K on car. No accidents, no damage, camber is -1.3 degrees, so it is in spec, but spec is also down to -.1 degrees. There was wear on the rear due to -2.6 degree camber and that was fixed by putting adjustable camber arms on the rear. Dealer actually stocked that aftermarket part for the rear. The front is still wearing the tires and we (dealer and I) felt if we could get the camber set closer to the minimum spec of -.1 Degrees we could help the wear issue. We tried the "cam" bolts that are supposed to fit in the struts to aid in the adjustment for this model, however the AC Delco part number that is for this vehicle (45K18036) will not fit through the holes on the strut. So I am asking if there is a known part that will fit this vehicle or if there is another way to reduce the negative camber on the front of the 2011 C70."
SOURCE: My C70 has way more wear on the inside of the rear
2.5 degrees negative camber is not within spec. You need new control arms in the rear. These will set your camber back to the factory setting and reduce your tire wear on the inner edge. The first shop you went to is correct, the camber cannot be adjusted, components must be replaced to rectify the excessive camber. Ive done a couple of New Style C70 rear control arms for this very reason, if your vehicle is under warranty however, the dealer needs to be able to prove that the car needs it. So if you dont have wear on your tires and when the toe was set it readjusted the camber (when you adjust toe it affects camber and caster measurements) then they cant prove to Volvo that it needs the control arms. I hope this helps
