1937 LaSalle Pinion Seal

[LeRoy DeVol]

I own a 1947 Cadillac and had the same problem. After removing the drive shaft flange, i drove the seal forward out of the cone toward the pinion bearing, then i took a small bearing puller and reversed the puller arms so they were to the outside. i inserted the puller to the inside of the cone And was able to pull it out with no problem. I purchased a seal (3/8" thick) & installed it in the cone. Everybody is talking about installing 2 seals to replace the original seal, but i used only 1 and that was 6 years ago & 25,000 miles with no leaks. The only problem i had was the puller i used was a little to big and i had to grind down the ends to be able to pull the cone. I believe the 2 seal idea was also good as they are very cheap. The main reason for installing 2 seals is that there may be excessive wear on the drive shaft flange & with 2 seals they will seat at different locations which will seal better.

Others probably work too, but that is what the guy sold me and it working so far. Only I can't drive the car more as its overheating and now I have the heads off cleaning out the cooling passages and waiting on my headgasket.
