12bolt rearend leaking at stress points
Permalink  
 


so unfortunately I found silicone seslant on the stress points of my 12bolt rear.

what do you guys think about that and what can I do.

I guess thats not a good sign and shows that the tubes are moving in the axle housing? 

is it a good idea to carefully weld the tubes tu the cast center? Or is there another way to strengthen that area?

thanks

It is common to weld up the tubes. I did not do it on my car, but my father did on his 67 chevelle. It may be worth trying before buying a ford 9 or something like that.

I would disassemble the rear end, install all new seals, check the axles, and ring and pinion play and have the axle tubes welded....at this same time you also have the opportunity if you wish to change your ring and pinion.

X2 on welding. Did mine before I started bracket racing and never had a problem.

It is a very common problem for the factory welds on the housing to seep a bit. I have seen in the past where people weld the tubes to the center section only to have the problem reoccur. The culprit is the poor factory welds. They can be cleaned and welded solid. The chance that your axle tubes have moved in the housing are minimal. It is best to weld the tubes to the housing for strength and fix the factory welds.

I see
I hope I can live with it for a while and just be careful with it, later there would be more work to do on the rearend but that will probably be done in winter.
If I decide to weld I´m gonna have to make a Jig?? Worried it could bent while welding...
I don´t know of any axle Shops here in Germany. Have to do it on my own :-/
