Diff fluid in drum brake
I have an 85 R80 and diff fluid is getting into the drum brake. It's getting in from the pressed in sleeve where the shaft that spreads the shoes goes through the diff. I've cleaned and sealed the end of the sleeve with RTV a couple of times but it always starts leaking again and of course soaks the shoes with diff fluid.
The diagram doesn't show the diff, but p/n 21 is the shaft that goes through the sleeve that activates the shoes. I hope this helps to visualize what I'm refering to.
Any suggestions would be apreciated.
