rsicard Posted October 4, 2011 Share Posted October 4, 2011 This question is for John Coffey or Mr Mortenson, concerning the alignment of the Drive Shaft in relation to both the third member and tailshaft of the transmission, if there is other than 3 degree opposite angles on each, can a CV joint at say the differential end of the shaft solve any potential vibration problems? Would like to know first hand experiences concerning this alignment issue. Thanks. Quote Link to comment Share on other sites More sharing options...
rossman Posted October 22, 2011 Share Posted October 22, 2011 (edited) I think it's a bad idea to run only one u-joint. You will get more vibration. U-joints are always used in pairs to help cancel out vibration caused their inherent non-constant velocity. Two CV joints would definitely smooth out the drive train and allow greater angular misalignment but it comes at a weight penalty.

Mike Mileski Posted October 31, 2011 Share Posted October 31, 2011 Lots and lots of driveshafts on factory four wheel drive trucks are made with a u-joint on one end and a double carden joint on the other. I don't think they'd do that if there were vibration problems with that design. Mike Mileski Tucson, AZ Quote Link to comment Share on other sites More sharing options...
rossman Posted October 31, 2011 Share Posted October 31, 2011 I was talking about combining a true CV joint (Rzeppa or tripod) with a single cardan joint. Double cardan joint shafts typically come with three cardan joints. Quote Link to comment Share on other sites More sharing options...
