We have a 2013 ML350. A couple of years ago we had front and rear springs break around the same time. As it was during Covid, parts availability was nil from Mercedes. I decided to have installed H&R aftermarket springs just to keep the car on the road. Since having the H&R springs installed we have had premature tire wear and getting the car aligned correctly is proving difficult. Now that Mercedes springs are available we are going to go back to an original setup. When looking into this there seems to be three different options for front & rear. I have made enquiries to a couple of dealers and they are not returning my calls. Does anyone know or can advise me on what I need to purchase please. The VIN is 4JGDA5HB3DA212677, with tow pack and a US vehicle. many thanks in advance.
