I read a lot of axle info but didn't find what I'm looking for.

What does the following numbers and letters mean?

S838M(orH)

3 55 88 6E20

Thanks

3.55 . Should be a 2 digit code on your door jamb sticker under "Axle"

3 55 is the ratio 88 is ring gear dimension and i believe 6e20 is a plant code. Google is your friend

JScatt, the door jamb has H9 as the axle code. When I typed the digits in, I thought the 3 55 was the gear ratio but wasn't sure about the others.

Thanks
