View Full Version : big job?

06-15-2006, 08:19 PM
when i bought my truck it came with a welded diff and im tired of my 1 wheel spin in the rear so im gonna throw it in

my question is is it a big job to swap out the old one in exchange for this welded one. ie will the teeth be easy to line up. new to this but im wanting to learn how its done and not pay to have it done. any tips?

also its probably smart to buy a new gasket correct or do u guys use liquid gasket if its not too bad?

how big of a job am i looking at?

is it just the gears or a full pumpkin? if it is just gears the pinion will need to be set. let somebody else do it, it can cause you moucho greefo

just weld the one thats in there right now

Yeah, it is totally easy if it is the full pumpkin. I had watched somebody do it once. And did my own in a couple hours, it's easy and you'll love it off road. On road?? I do, but tires wear quick.

ps, I'm just learning too, if I can do it so can you

make sure when you pull the axles you dont rest them on the seals or you will bend them and they will leak like a bitch.....i have had experience

this is what a 3rd looks like

'3rd' is the whole pumpkin. And there is no back cover on a toy axle.

Toyota uses a removable 3rd member instead of the usual carrier crap the most domestics use. Makes it a lot nice to work on as you can remove the 3rd and put it on the bench or setup the gears etc.

To pull the axles there's 4 bolts on either side that hold the axle shaft & brake assembly to the axle housing. Just undo those 4 bolt and slide it out a few inches till the shafts are clear from the 3rd. if you're lucky there will be enough slack in the brake hardlines that you won't have to undo them and bleed the brakes.

think i'l tackle her tonight or tomorrow morning
how do i know how much diff fluid to put in after?
any special kind i should use?
so liquid gasket will work? or just grey silicone
sorry for all the questions i wanna do this right the first time
also will i need to pull the gear shafts and whats the best way to do that as i think i probably need to in order to seprate the gears fomr the diff

I used blue silicone, and fill it till it starts to come out the fill hole and throw the plug in. Yes you'll need to slide the axles out a bit, so as Ern said, there are four bolts on each backing plate, undo those and slide'm out. If your hard brakes aren't that long, you will have to undo them and bleed the brakes when done.
