I have a friend with a 2007 MDX with 300K miles on it. The rear universal is sloppy and I think causing a substantial vibration at 40 MPH and up. Is there any way to change that and put a regular universal in it, or do I have to get a new driveshaft? I can't believe they want to replace an entire driveshaft at God knows how much to fix one ten dollar universal joint.
