grr thanks to tom at drift prac night i have a doubt as to the ease of doing this now. (thanks man)

he was saying something along the lines of having to go through the backing of the diff remove the centre and remove the pinion to replace the seal. now seriously wtf.... true or not true?? can someone please either confirm or deny

yeah if its your pinion seal leaking you will have to take diff centre out of carrier and remove pinion and the only way to knock the seal out is from the opposite end (being from inside the carrier) and if the flange locking nut is taken off you need to set preload again on the pinion.

not to say you MAY be able to just remove the locking nut and flange and try to get seal out while still all assembled leaving the pinion and diff together, but you might not be able to get preload correct. (not really recomended but let me know if someone has done this)

also when you get the tailshaft flange out check to see if where the seal runs on has made a groove in the flange and if it has, to order a speedy sleeve to cover the groove along with a new seal

Not exactly my words but close enuf :P

It can probably be done the other way aswell. Never tried so don't know, only what ive been told/read

yeah kev, sadly the way the design is its best to pull the centre out and redo it properly.

i heard this story before and thought i would try cause i was rebuilding my diff any way, and i didn't feel confidentint the way it was going to go back together. the collapsable spacer is easy too collapse when doing up the pinion nut.

if you do it this way you might as well change all the bearings and shit too. you can buy new collapsible spacers for like ten bucks so make sure you get one of them too if you redo your diff.

nah. they were really reasonable. from memory they had it in stock. if you wanna go toyota, go to city toyota on aberdeen street. i use alot of dealerships for parts and they are by far the best. so far other than castle hill in nsw they are the only toyota dealership that doesn't give me the shits when ordering parts and they always get it right.

you guys done this work to a JDM or ADM rear axel? been told by Ben and Steve I can just go through the front for the pinion seal

i checked toyota on the weekend and the only one in WA is in broome so i might be chasing it from therebut i havent tried anywhere else.

My diff is a JDM but ive had to replace other parts along the way so i had to pull the whole thing out anyway.
i dont see why you couldnt change the seal from the front? but personally i would take the centre out.

yeah, like i said kev you can do it from the front but i would recommend taking it all out.
if you wanna try it from the front just make sure you mark everything exact and do it back up to the exact same point.

do it up too much and you will crush the collapsable spacer, too little and you will create float in the pinion

btw mine is jdm. i wouldn't have bothered to fix it on s series, just let the fucker leak
