How to fit freewheeling hubs.

Check the Vacuum lines that operate the ADD system to the front diff

If you mean Pic 1, then you have 4 wheel drive but not free wheeling hubs

Ah OK, it can't be working anyho because any muddy feiuld turns into a donut ring even in 4 low. God knows when oils were last changed so I'll be starting there

I'm confused... My hub looks like the before pic, does that mean there is no auto or manual locking hubs fitted & therefore no 4wd?

FW front hubs

Just had freewheeling hubs fitted to my kzn130 3.0 I like the truck more as it seems to coast better, turning is lighter and maybe another 25 kilometres to a tank. There is less engine braking when dropping out of over drive , I use this a lot, but I can live with that.

Free wheel hubs

Spot on there Vince.
Ref picture 7,when I tried to refit the bolt and washer to the end of the drive shaft it wouldnt fit,the threads of the bolt did not actually make contact with the end of the shaft,spent a couple of hours over a bacon butty pondering,in the end I gave up till I could come up with a solution.
I could have just used a longer bolt,but didnt want to chance it.

Any ideas?????

Just to let people know, the freewheeling hubs Roughtrax are currently selling (these) need the cone washers to be refitted.




Incidentally, after having the 3.0 manual for a week, I've just refilled it with fuel and fitted the freewheeling hubs.There's noticeably less resistance turning the front wheels after fitting them
The 'before' was 29mpg on my run to work. I'll post the after next week when I fill it up again.

You need hubs off an IFS pickup, 97-on to fit a 2nd Gen Surf.

Hi-lux hubs

just checked and the hi-lux half shafts were bigger, so the splined collar is too big for my surf.
might be able to change the bearing/collar as its a replaceable unit in the freewheeling hub housing. i'll have to go ask at toyota.

hi-lux freewheeling hubs?

Hi.
would a set of freewheeling hubs from a hi-lux go straight on?
it looks like the same hub and axle end arrangement (as i remember).
i think i've still got a pair somewhere....
saves fuel, more beans, and looks good in the wheel centre too. all good

If you fit locking hubs, can you then do away with the ADD system?

You can do away with most of it anyway, no need for manual hubs.

Anyway, this has ben stickied, so we really shouldn't taint it.

[slobodan]

No because apart from some very early models the Surfs do not have automatic hubs as many believe. They have ADD which is Auto Disconnecting Differential. It's the diff that engages (via a sliding collar on the drivers side shaft) and disengages, not hubs.
