I just purchased this truck and I am going to replace all the axle seals or at the least try to but I have hit a snag I cannot find the numbers to tell me what type of axle I have, I do know they are Spicer ( Dana ) and that is all I know. I have scraped the housings as best as is possible wrote down a bunch of numbers and none cross to Spicer. The VIN number only says it is a Glider which came without the drive axles I am open to all suggestions also I can see where something was glued to the axle. Both axles had a metal tag on them and the number went nowhere, any ideas?
