so today I just switched out my driveshaft and ujoints and noticed that the plate on the rear diff that the ujoint flange bolts onto could be turned by hand about one centimeter or so... is this normal... I had to replace the drive shaft and all ujoints b/c the front ujoints broke off when driving... the truck drives great with the new shaft put in but i just didnt want for these ujoints to get worn out the same way if there is something wrong with that plate on the rear diff moving... thanks for the help guys!
