hey i need to know where to weld the spider gears to make the thing have a locker, im going to be using some cheap hobart wire feed mig welder, not a arc welder,(which i dont have access to) so if anyone wants to tell me how(pictures are worth a thousand words) i would love it,
thanks

holy crap

 

check out THIS post on the Pirate Board.

You must, MUST clean the third very well, absolutely no gear oil can be left to contaminate the welds. If your gonna use a little welder, preheat the third in a gas grill or oven to at least 350 to 400 degrees prior to welding. When you've completed the welding operations, put the third back into the grill or oven, reheat it, and let it cool off slowly in the grill or oven. This will make it weld better and allow it to be stress relieved after welding. The one third in the post above used plates to further solidify the third- that's a good plan-

Do a search at Priate 4x4 and you'll find pics. Do not post this question there or you'll be flamed by thousands of responders.

 

Note the person who did that one also welded the spiders to the carrier, I do not recommend doing this. The cast metal of the carrier is quite weak in comparason to the spider gears and will break.

Also the ones pictured there are 4cyl diffs, if you happen to have a v6 diff have fun. They're not open like the 4cyl ones so they can't really be welded. A trick the drag racers would do for this is to full the cavity with molten lead.

Oh ya, and parking lot maneuvers are gonna suck with it welded. good thing it's not your DD.

 

so does the 3rd have to be out of the pumpkin? and when i weld it looks to me like you weld the spider gears so they dont have anywere to go basically right? thanks

Ideally, and yes. If you don't know how to and/or don't have the tools to check gear setup then don't take it apart. Cover up the gears as best you can to keep spatter off them and make it so the spiders can't turn.

Did you get my email about the CB?

 

havent got the email yet, i think im just gonna have my friend do mine, he did his 83, same basic prinicpal i think, so im not gonna mess with it.

They can definately be welded, it is just a little more labor intensive. Kinda like welding a 14 bolt...

Someone is selling one on eBay, current bid @ .02

 

thanks for the help rob but the diff there is out of a tacoma, i dont think it will work will it? im putting this in the pickup not the tacoma....if it worked it might be worth doing though....anyways thanks dude..

wade

 

Tacomas should have an 8.4 diff unless it came with the TRD electric locker - then it is an 8".

 

so the short answer there is no, it won't work...

 

44runner, i sent you an e-mail and a PM, if you get a chance and got either one of them could you respond?
