I would suggest it is grease that has "liquefied" and most likely coming from around the lower pillar spring. As you had the suspension rebuilt the reservoir would have been filled with grease, driving the vehicle will have distributed the grease to all areas for the first time and this is residue. It should stop and not be an issue, but keep an eye around the lower part of the suspension and top up the grease reservoir.
