im having problems, i have a 1969 bronco, the rear axle keeps leaking out of the brake drum, it is gear oil, its leakin from the wheel seal, i replaced the seal, i got a 3300 LB seal from autozone, and it still leaks, is anyone else having problems? it has 11" brakes so i assumed that it was the bigger seal, could i get the smaller seal and would that fix the problem? any help would be appreciated.

you might want to look at your axle where the seal rides. it might be worn down a couple thousands of an inch causing you to not get a good seal. i had to replace both of mine because of this problem.

Make sure your axle vent is not plugged up. The vent tube fitting has a small hole that can be eaisily blocked with mud or dirt, causing the rear end housing to build up pressure when heated up.

well the problem is, it hasnt run in 2 months now, its been in my garage, we took it apart, put new gears in the rear axle, and put new seals in it, and it started to leak, im gonna take it apart again and look at the axle shaft, and determin where its leaking, thanks for the help. i do have another question, im trying to make a hose to sit in the gas tank, not this car, just a camp stove i have that uses gasoline, would the hose they sell at like home depot, thats clear and has crosses through it suffice to sit in gas? what is the best way to go, i know the regular fuel line is treated on the inside, but not on the outside.

Can you put some stainless tubing in the tank and stick a flare to hose barb fitting on the end outside of the tank. then you won't have to worry about it ever. That's how I made my EB fuel lines (not in the tank, but along the frame from just outside the tank to just next to the pump, those pieces are rubber fuel hose).

Just because the brakes are 11" doesnt mean that you needed the big seals. the brakes could have been switched at some time. check bearing and axle size as well as the housing size. check the size of the seal ID you put in to the axle od. same???

well the problem is, the sticker on the door jamb, i guess is were it would be is gone, along with the vin plate, so i really dont have any way to find out what type of axle it is, even though the vin number has nothing to do with the rear axle, and the plate from the rear axle is gone to i lost that a while ago. thanks for the advice for the gas line, i will try to do that.

Not likely. 11" brakes will not bolt directly to 10" brake axle flanges. The flanges and axles would have needed to be replaced to make it work.
