Title: pinion seal part number
Post by: Dan Johnson on August 24, 2024, 11:26:11 PM

I have a 2002 Marquis43 foot with tag axle. The pinion seal started leaking. Where can I find  or what is the part number?
Thank You!

Dan,

You will first have to identify what axle you have, I believe it is probably a Rockwell, but you will need to verify.  Look for a stamping or a tag on the differential.  From there any heavy duty truck stop should be able to narrow down what seal you are likely to need.  A good NAPA can do this also, but there seem to be fewer of those than in the past.
