I have done considerable work to my Volvo sx-a drive over the winter. I replaced the universal drive arm and the bearings and seals on the drive arm bearing carrier, the gimble bearing and seal. I also installed the updated infamous POS 12vt. external trim pump. However after patting my self on the back I think i have another issue. I walked out to a small puddle of oil under the drive and noticed that oil is leaking out of the speedo port on the leading edge of the lower drive. I did not touch anything to do with the lower drive itself other than to change the oil. Any ideas to what this could be from and possible cheep fix.
