Make sure the driveshaft yoke sits the correct distance into the transmission tailshaft housing after putting those springs in! If it now sits in the right place that means the previous owner didn't lengthen the driveshaft after putting in those 22" front section leaf springs and the tailshaft bushing might be worn or damaged.
I had to take the drive line to a shop .He had to shorten My drive line about 2". I took measurements to Him after looking at it he said everything on the drive line was fine .
