This is a new very correct and high quality set of hub seals seals. This is the seal that keeps the grease on the rear or inner bearing in your hub assembly. These are correct for the front axle on the CJ2A, CJ3A, M38, M38A1, M170, CJ3B, and very early CJ5 with the 134F four cylinder. They are also correct for both the front and rear hubs on the MB and GPW. These are a must in a vintage restoration. I replace these on all my restorations as a fail safe. This sale is for a pair or two seals only. The measurements are 2 7/8″ OD and roughly 2 1/8″ ID.
