My friend bought a 2003 viper ER with 3800 Canada miles on it. Yesterday he drove it for the first time and I wanted to try it also. I noticed a nasty drive line vibration in it. I switch the drive belt for the other one in his sled and the same vibration was there (I suppose it's possible that both belts could have a burned spot, even though none were visable). In the garage, I pulled his speedo side bearing cover to inspect the drive shaft bearing. It looked a little rusty and is suspect. The vibration is only under hard throttle. Coasting is fine and normal cruising is fine. My question is, can that bearing cause this symptom. I guess with 3800 miles it's not a bad idea to replace it anyway. There was too much snow in the skid to really get a good look at the drive cogs and the inside of the track (which is the nipple track). Any ideas? Doug
