When I replaced the rear engine mount twice in the past, I also replaced the other two mounts. I remember that they weren't as deformed as the rear engine mounts.
Hello L90E, I have replaced the rear engine mount twice in the past. In each case, the position of the hole before replacement and the position of the hole of the new part were significantly different. It seems that the shape of the rubber is deformed due to the weight for a long time.
