AISIN Manual hubs - help!

[The Lovely Boyo]

Hello,

I'm working on my mates Hilux pickup - 2.4diesel 1992 solid front axle. It has a lot of play on the front nearside wheel bearing. I've already dismantled my hubs serveral times so I know how to get those off.

These AISIN manual hubs have me stumped. I have read this article - http://toyotasurf.asn.au/techsite/hubs.htm

I have taken the front cover off - the 12mm bolt in the centre of the drive shaft is missing.

Do I need to dismantle the manual hub (circlip is a right bugg3r to get to)????

The cone washers are solid - wd40, heat, BFH - you name it - I've tried it.

Cone washers are usually, loosen nut, #### side of hub (along side the hole for the cone washer) with a big hammer and they pop right out.

Try using a punch on the end of the cone washer stud as well, this often works, but don't mess the thread up.

You don't need to take the circlip off to do the wheel bearings.

Tried that - no movement at all! They look like they have been on there for years

Will try this in the morning

Thanks Tony, started bl00dy raining now so I'll have to have a look tomorrow.

Sorry for sounding dull - I have to take the front cover off the hub, and the clutch pack inside, but then I just take the outer hub off (assuming I can get those pesky cone washers off)

give it a good soaking with WD40 now, and also wind a couple of bolts in the threaded holes when you try again, and see if helps. Don't go nuts, in effect they will clamp the cone washers on as you are pulling against them, but sometimes it helps just to stress it differently while trying.

Yup.

I've never needed heat to get them off.

No threaded holes to pull against on these hubs - WD40 is applied and soaking in right now.

Hopefully tomorrow brings a bright new dawn!

Yeah, forgot they are only on the drive plates.

A GFH normally comes though, don't be a afraid to get 'firm' with it, one hearty solid blow get better results than little girly taps, but mind the wheel studs.

OK - Cheers Tony,

VBFH will be applied with vigour on the morrow.

[The Lovely Boyo]

OK - Just an update.

Applied BFH with crazed look in my eye, no girly tap tap tapping.

All done within 30 minutes.

One cone washer flew out and landed about 20' away - took some finding!

Oh, yeah, had to take the circlip off to get the hub off.
