Yes it will be an issue. The original style seals were made of rawhide which wore into the steel (Chicago Rawhide was the company, think Chicago had any leftover rawhide haha; it is now CR now that they use modern neoprene and urethane)

There was a thread on this very recently about using Redi-sleeves to restore the diameter, a search should bring it up.

If this is not addressed you will leak gear oil into your brakes

oops '30 coupe beat me by 2 min

Yes, Nephew, I remember that them leather pinion seals on the early Mopars would SQUEEL! The factory MUST have installed them DRY! We'd seal the dust slinger to the pinion nub with DUM-DUM & fill it with ATF & after 1/2 hour, or so, it would soak into the leather & the noise was GONE, PERMANENTLY!
