Folks, as soon as the temperature goes back to having 2 digits, I’m going to replace the pinion seal on my solid axle 65 Tr4a (mine is leaking). I’m assuming that the seal is made against the pinion drive flange, is that correct? If so, then should the drive flange be replaced as well? I’d hate to put it back together and find it still leaks because the flange sealing surface is worn too, or would wear be apparent?

Thanks

Jim

My suggestion is to try to polish the sealing surface of the flange. If you can't polish away the mark left by the old seal, put a Speedi-Sleeve on it.

I don't recall the size offhand, but it's easy enough to measure.

Randall, I was just on the Moss site and they have the Speedi-Sleeve for the flange.

Thanks!

When I was taking the picture of the clutch slave cylinder today, I decided to scope out the job of replacing the differential pinion oil seal. It became apparent that there is not a lot of space to move the driveshaft out of the way to get the rear drive flange out. It’s sort of boxed in by the exhaust, frame rails, and that square bracing plate where the rails angle toward the center of the car.

Can the drive flange be removed without removing the driveshaft from the car? If the driveshaft has to be pulled, can it be removed without dropping the differential? (my Tr4a has a solid axle)


Thanks

Jim
