does any body know anything about this? I was talking to some jeep rock crawlers (looked like ford 9" on most) anyway they were talking about lead locking from what I understood I think they fill the spider gear with lead?????/
any body have any info

thanks

just curious they were" jeep guys "and you know if they arnt in fords right off the bat you know they are a bit twisted

 

I've never heard of such a thing, but I bet they are just talking about welding your gears into a spool, just another name for a "lincoln lock".

 

From what I understood they used the lead to allow a break point or something. so that the lead would give before something else broke. got to thinking that it might be a good idea easier to pop the cover and cleanit out and reload than buy new parts
still curious let me know if you get any more info

thanks for the reply
I am new to this whole truck obsession, my girlfriend goes to yoga to relax, I go out to my garage and start tinkering, wish the truck still fit under the door. Have to make a taller door!

 

No problem, I can relate to the obsession Yea, its tough to tell with those jeep guys. I still don't see how they would use actual lead though, its to soft for anything. Then again, I don't know much about those wussy D30s they run either

 

Maybe the idea about lead is you can heat the gears to remove it?

 

Interesting concept... I'm betting it would work - for a while (I don't really think of welding spider gears as a permanent solution either). I'm thinking it doesn't have to grip the outside of the gears and hold; you can pour it in hot and its going to fill in everything, including between the teeth of the spiders, reducing clearence to zero...

After a while of forward/backward movement the teeth would be trying to squeeze the stuff out as the lead held everything else stationary; some play would have to develop in it - I'm not sure what that would do to side loads, not to mention some is bound to work it's way loose in the case and get into the bearings and ring/pinion... not pretty. It would take a bunch of the stuff to completely fill it and the fumes from heating it up wouldn't be too good for a fella... sound like a solid theory?

I think I'd stick to Tracklocks and mini spools...

 

Thats actually a pretty good theory........I still can't see that being what they really do just for the durability/reliability issue. Like you said, they'd up with the lead breaking up and tearing everything up. My moneys still on 1) they were badly describing a lincoln lock, or 2) they were trying to see how gullible the Ford boy was and if he would tell his buddies about it so we'd f-up our pumpkins.

 

Hey guys I am pretty sure that they were serious, as far as i could tell it was to provide a weak link, you now when something has to give it is something that doesnt cost big bucks. I was wondering if it does squeeze the lead out and slip to save somthing else what do they do and where does it go? it is heavy but is the fluid not moving to fast for it to settle and if it did settle is there enough clearance for it not to be a problem with the ring a pinion???????
like I said I dont know but if that is what they did it worked that day the one guy climed a very near verticle 10 foot high rock wall that I had a hard time to climb on my hands and feet
any ideas?
thanks

 

I thought the jeep WAS the weak link? But seriously, its not like I know it all but the fact that I have never heard of this makes it very questionable. I've been wheeling for many years now and travel in some pretty hard core circles and have never heard of such a thing. If you want cheap just weld 'em. Otherwise do it right and put in a detroit.

 

thease guys seemed to be very extreem and it may be some thing they thought up and decided to try. I thick theyworked in some kind of shop, and fabricating and parts wernt hard to come buy.(must be nice) as far as the jeep being the weak link I think that the only jeep thing left was the body panels.lol... both had chevy 350's one had a ford 9"rear and I think dana 60 front and the other was some kind of surplus military axels(I could be wrong but I think he said 2 ton?maybe rockwell or something like that.
so when they say its a jeep thing, I just laugh and ask what the windshield!
thanks for the input
