Old seal is good, no leaks or seeping. Should it be replaced when installing a new axle right side?

Should not be a problem. Some of the really cheap axles are not the exact size diameter and may leak with a used seal, but that is not normal.

Thanks guys. Left the old one in and replaced the axle. The right side is a walk in the park compared to the left or maybe I have done enough of them to make it easy.

Absolutely agree with Klauss.

If possible, try to measure the diameter of your existing axle at the transmission end and make sure that the replacement is the same or at least within a few thousandths.

I first learned that I should measure when I did an halfshaft replacement on my sister's Civic. Didn't realize how much smaller the diameter of the replacement shaft was. They looked the same to the eye and it fit up fine. She left for a 1500 mile trip right after the replacement and lost about 2/3 of her transmission oil during that trip because of the poor sealing of the new axle. Amazing that the gearbox didn't seize up - it's still going at 225K miles.

Bottom line, compare the diameters whether or not you decide to replace the seal. Me? With your original seal at 14 years, I'd probably replace it.
