when you remove the gold dust cap on the ADD hub, there is a bolt underneath. does it need to stay? does it matter if it does or does not?

 

i think thats the hub bolt .... its the really big one right ?

 

nope, it's got a 12 or 14mm head. dead center on the hub

 

it's been removed in this picture

 

ADD is vacuum.

The flange is not a hub.

No need for it, doesn't hold things any particular way.

 

okie dokie. isn't that still part of the hub?

 

I put it back in, but it doesn't really seem to hold to anything like it did in the ADD flange...

 

The .pdf has it installed....and so does a picture from the service manual...Also in this link... https://www.yotatech.com/forums/show...in+hub+rebuild

 

And the .pdf to make it easier to find....http://www.yankeetoys.org/Documents/AisinHubs.pdf

 

I just did an ADD swap and I thought it helped to retain the cv axle from pulling out or just moving around so much--I know I had everything apart and couldnt remove the axle until I remembered to remove that bolt, if it is the gold 12mm bolt your talking about. I may be way off on this, but it's just an idea

 

All I could tell it was there for was to hold the drive flange on if it came loose. I dont recall my Warn Hubs using it.

 

I just changed mine over and I replaced that bolt so it wouldn't get lost if I needed it later

 

The bolt goes in to assist in holding the AISIN hub in, just in case you lose every single cone washer & associated bolt...'

 

My warn hubs have it, dont remove it otherwise in the rare case everything comes off it will still hold on. Wanna replace some bolts or an entire hub?

 

I replaced my CV shaft on my 90 4runner 6 weeks ago and when we pulled that dust cap off, the gold washer/bolt on the end of the shaft was what was holding my shaft in place. We dug further and found that the C-clip that snaps onto the little groove in the splines was very loose and easy to take off.

So dont permanently remove that washer and bolt, besides, it's only a few grams of weight, nothing major.

 

I never re-installed mine. Seemed to work fine to me.

 

same here

 

you have to take it off to install aisin manual hubs. after installing the manual hub body, it's optional whether or not you want to put it back on.
