Well I have installed the new U-joints with only minimal problems but another problem has turned up. Bart pulled the 2 driveshaft halves apart without marking them. When I assembled them the phasing of the U-joints is off (see photos). Even if I rotate one of the halves 180 degrees they still don’t quite line up.
Bart did find a painted on line on one half and a center punch mark on the other half but when you slide the splines together with those marks lined up the 2 halves are 90 degrees out of phase or completely wrong in my eyes.
I looked at the driveshaft I took out of the parts car Bavaria and they are also a good 10 degrees out of phase so I don’t know what to think ? I realize these are older cars that have been worked on by numerous mechanics and things may have been changed thru the years but I’m just not understanding why I can’t get them to line up. I have successfully shortened probably 30 or 40 driveshafts (admittedly all American 1 piece) thru the years and getting the U-joint phasing perfect was important but I never expected phasing problems :confused::confused::confused: with a stock driveshaft ? ~ John Buchtenkirch
