I searched on this and found some answers, but I was hoping to get some fresh ideas.
Recently upon heavy acceleration/load, I am getting a pretty heavy vibration in the pedals and steering wheel. I had my left drive axle replaced about a month ago, but I highly doubt this is the problem. This happens in all the gears, but is more pronounced in the higher gears. My father suggested that the clutch could be on the way out, but I'm not getting any grinding of the gears or any surging at high rpms.
I'm thinking motor-mounts, but is there a way to check which one(s) are bad?
