I just got towed home and put the car up in the air to find a driveshaft bolt had backed out and was missing. I noticed all of the bolts are loose and a ton of grease and been flung out into the underbody of the car. Thought on the driveshaft? I’m leaning towards replacing it but I’d like to know what you would do in the same situation. It doesn’t seem to be in bad shape aside form the missing bolt and missing grease. What should I get if I replace it? Carbon or aluminum? DSS, QA1 or other? Also on a side note I’ve been searching for some false knock and I think this may be it.
