Small pin hole in left rear axle. A half inch away from the bolt below the driveshaft. It appears to be a small flaw on the outside. I'm thinking about using J-B weld on it. Any comments would be welcome.
clean the area with solvent - carburetor cleaner, disk brake cleaner etc. and seal it with black RTV
My Hogs's head has a crack near the block and it works!
Should work ok. Have been there, done it.
Hints: Clean the area very well with lacquer thinner.
Use JB Weld "Quik" version, the original will drop away while setting, the "Quik" you let get almost tacky hard, but still soft, press it in fast, it won't droop away like regular JB Weld.
Another vote for black RTV. From oil leaks to big cracks in radiator tanks. This stuff works. I was much less impressed with JB Weld. It has it's place.
The only problem with your method of sealing that I "see"(think) would be that when you clean it up the oil inside would keep dripping. You might be able to take out the bolts and spread the housing in order to drain out all the oil. Then clean and seal.
Norm, I have let it drip until it quit. I then raised the front of the car. I will let it set for now and allow the oil on the inside to drain away from the hole. I don't want to take it apart as I have done two Ruckstel's and one other axle in the last six months. Also I need to change out high speed ring and pinion for a stock setup for my speedster. I'm hoping for a "easy fix" on this one.
cast steel, welds nicely, i would zap the spot with the wire feed
Black RTV or JB weld is the ideal fix in my opinion. It will last as long you have your T.
