Torque setting for the hub nut 86 AW11 MR2

[Chubs]

Hi,
we're changing the wheel bearings on a mate's aw11 mr2 tomorrow.
Just need to know the correct torque setting for the main nut that holds the hub in (whats this nut called?)
OR if anyone knows a good way to get it right without using a torque wrench, let me know, because i'll have to buy a wrench otherwise.
Cheers!

Front right wheel, by the way.

the main hub nut on the front is 90ft-lb / 123nm

I'm thinking it should be roughly the same procedure as on a sprinter, if the bearings are similar.

the way i did mine was (on the advice of a few people)

pack the bearings with grease, tighten it up, spin the hub, loosen it a few times,

then i did it up looseley, got a big shifter onto the nut and let it "drop" the nut tighter. then i gave it another quarter turn and put the split pin through.

The toyota manual describes how to do it with a spring balance, which would probably be a better way to do it, but mine seem ok.

hope this helps, should give you an idea at least.

aw11s run a different setup to the oldschool toyotas that most people are used to seeing. ball bearing, similar to the fwd stuff.

find the aw11 big green book online, it's got the full procedure, tho i'd pay someone to do this cos it's just a pain in the ass.

goodluck

Haven't pulled mine apart, but aren't the bearings in a case on the AW11? You remove the whole assembly and replace it, hence the nuts aren''t tensioned like normal wheel bearing nuts, as detailed below.

I THINK. Not sure.

for one thing he didn't ask how to do it

beside they aren't hard at all i have done mine, pull the hub off, remove stub axel, press bearing out, press bearing in, refit stub axel, refit hub

Where can i find this 'big green book' ???
If its different to a normal hub then i might need to read up on it. I've got the shop manual to a celica that i'm working off.

90 foot pounds is about a medium sized grunt when pulling on a good sized ratchet

Don't worry too much if you dont have a torque wrench as it is hardly a critical setting and there is a cotter pin in there to hold everything in place.

It is highly unlikely that you would be able to break one.

I recall them being a normal hub

the bearings you'll have to get pressed in though

from the bgb

[Chubs]

That looks a whole lot more complicated than is described in my celica manual!!

Can anyone give a brief run-down of how to change the bearings with an mr2, or send a scan of the appropriate pages from the manual, or even better show me where i can download the BGB?

Cheers

If you're talking about a RWD Celica then yes it is a lot more complicated. The bearings need to be pressed out rather than just popping out like an old school hub.

[Chubs]

So... what you're saying is that its a job for the mechanic? Its not possible to be done without an expensive press?

[wiso]

you can pull the hubs off your self, get the axle hub out, take it into a workshop with the bearings and get them to press the old one out and the new one in, then re assemble yourself. thats what i did and always do

[Starfire]

You can unbolt the hub from the car and then take it to a mechanic to press the old bearing out and the new one in. They shouldnt charge more than about $10 each for that.

If you are trying to get the tie rod ends off of the hub after 20 years they will be damn near impossible. You will need to get a separating tool for about $15 at your local speed shop. It is a wedge with a slot in it - stick it under the tie rod end and give it a belt with a hammer...
