Don't remember where I read it, but I saw somewhere about using lead to lock a 9 inch rear end. It involved pluging the holes in the carrier, and pouring molten lead into the carrier. That would freeze the spiders up, and was supposed to be really reliable. Anyone done this? How'd it work out? How much lead did it take?
I know that 9 inch spools are cheap, but hey I'm 16, live on my own and have no job, so what can I say, I'm a cheap bastid.

 

Do you have access to a welder? that would be a helluva lot easier than pouring moulten lead in the carrier. In order to do that you have to have a way to get the lead to a liquid. I would think that the lead wouldnt be strong enough anyways... Pb is very malleable

 

x2.. It would probably work, but getting that much lead and melting would also be fairly toxic as well.

lincoln locker is your friend..

 

yes I have done it, yes it works, and it's soft enough that you have just a little give so as to not break stuff as much. Lead melts at a really low temp (621deg F actually) so it can be melted with a torch real easily. Find a tire shop and get them to give you some of the old wheel weights.
Ok that was the good points of it, but a mini spool is like $15, and takes half the time (or less) to install vs pouring in the lead, and can be removed if you decide that you don't want it in there for some reason like you decide to sell the vehicle.

 

Wow, see I never knew that a mini was so cheap because I never really looked. Is the stock for the bronco 28 or 31 spline?
I've heard people say that the 9" is hard to weld because of limited access in it. Is that true? On the amount of lead, I've got probably 30 or 40 pounds of lead casings off of power cables, and an oxy torch so that wouldnt be a problem. Not really saying I would want to lead it, but it was running through my head, and a little bit of pointless knowledge never hurt anyone.

 

the 9" is hard to weld but it can be done. the bronco that you have in your sig should be 31 spline axles, and even if it's not it's a good upgrade just find a set of axles for it if you get a 31 spline mini spool and find out it has 28 spline axles, and since you moved back to Iowa I have 2 or 3 full sets of of 31 spline axles that I don't use anymore since I switched to superiour axles in the ranger so I am sure we could fix you right up on that score. Heck I probably have a mini spool sitting around here too that I don't use since I went to full drag spools (actuallly I am pretty sure I do)

 

Like monsterbaby said, your 9" will have 31 splines, and mini spools are cheap, and will do the same job, but make sure you have a good strong center pin. I've seen chromoly center pin(that are suposed to be really strong)on ebay for really cheap($10 max).
