[ROVERNET - UK] Drive shaft vibration

Greetings all. Another item you may want to check for vibration is to look 
for dints in the driveshaft, of course check the ujoints as well. The 
ujoints can cause a problem if they are seizing or have flat bearings. This 
may not show up unless you unbolt one end of the shaft. Regarding the dint-I 
had a van once that had a very small dint in the drive shaft. There was a 
terrible vibration at 70km/h (40mph). The P6 of course has 3 shafts with 
ujoints. But then Rovers are always 3x the fun.
All the best, Ron.>From: "Slatskars" <slatskars at comcast.net>
