Am working on a brake job for a Dodge Cummins 3/4t pickup with a Dana Spicer 70 axle. There is a curious thin steel cone with a lip that is installed onto the drum before it is placed on the hub. Then the wheel studs are installed (I believe this is called Inboard Brakes where one must remove the axle bearings to remove the hub and drum, and then one can work on the brakes and or separate the drum from the hub. The hub and drum are id'd as Budd. I am particularly interested in identifying the correct name of this 'cone'. And if you think this is a worthy purchase and where one can be procured, etc. The local Carquest does OK but doesnt have a lot of heavy duty experience. Have not seen this before: on our other one tons, there is no such cone. These trucks use GM corporate axles. We checked with others and they say their Ford axles in this vintage of around this era (late 80s to almost 2000) do not have this feature. This seems like a good idea to divert oil seal leakage away from the brakes, which without the cone, any leakage will ruin the shoes.
Seal drip gutter ccone This is the item (cone) with the brake drum installed. I took the hub, cone, etc to the local truck repair shop and the the truck brake and clutch repair shop .... all gave the parts a good examination but concluded with the look we call 'deer eyes'. Still wondering what it is called and where we can order others.
We have searched the internet and consulted all wise mechanics and have yet to determine this part as to the name and source of supply.
