Huge Movement
As has been mentioned, there will indeed seem like a lot of play when you twist the driveshaft. You won't know for sure if it is excessive unless you do remove the cover and check the backlash. First, check to see if your four torque arm bolts are still tight, as I suspect that is where your clunking is coming from. Mine did that when the bolts loosened up. Bob
Its not that anything came "loose"... just things are shifting alittle. Ive learned to live with it and I just recheck the bolts every so often.
And what everyone else said about the DS maknig it seem like it has too much play is accurate.
