Pretty much ever since I have had this Quick Performance 9" rear axle, I have fought the passenger side axle seal (or the lack thereof) leaking rear end gear oil. QP uses a Moser Billet Torino style (big Ford) axle end and Moser axles with sealed bearings pressed on them. Their thought is the sealed bearing will stop the gear oil from leaking...it doesn't.
I finally learned that there is a step down inside the end that a National part #473229 seal fits into so I picked a couple of them up last week. Here is what the axle end looks like.
and here is what it looks like with the seal pressed into place.
ID of the seal is 1.5" which matches the axle. Sure hope it works...
I cleaned a LOT of leaked gear oil up today. And I just LOVE the smell of gear oil.
Also put a new E-brake cable on the passenger side and test drove the car.
Everything feels pretty good but it was hard to make a comparison with those old stock size tires on the car, need to get my new rims cleaned up and sealed and some new rubber on them then really take it for a shake down run.
