your support that was in the car had a lot of miles on it, let us know how the new one last, ,
maybe thak your car back where u had the work done ask if they aligned the drive shaft
when they reinstalled it on one side there is single hump or notch ,,, and on the other
\half of the drive shaft there are 2(two) humps/noches ,, align the short shaft to split the 2 notches
I will tyu to post a picture later today .. jim
