auto hubs shagged

[mighty trooper]

yea hi there i think i need to replace front auto hubs as when 4x4 under load get a mean bangin sometimes like its slipping or something can i get some 2nd hand manual ones off a mu or bighorn and will they just bolt on easy or is it gna be a bit of shaggin round should i get some more auto 1s or can i reapiar the old ones??

[pig75]

Yeah they just bolt on but make sure you get the bolts and circlips for the manual hubs the bolts are different and I can’t remember about the clips

[geeves]

Circlip is also different.
There is a catch to watch out for. Pre 88 bighorns have a different spline so are not interchangable.
Also wreckers get top dollar for original manual hubs. Some new aftermarket hubs are cheaper but dot touch them. The asin hub is almost unbreakable If seen a ORC brand hub explode driveing across a paddock. It was his third failure in 3 trips

I got mine off a ute being sold in pieces on trade me for $50 gave him my stuffed autos so he could still move his wreck and changed them in about 10 minutes each and that was only because I had to remove his front wheels (chrome surrounds on hubs) funny I ended up with his wheels later ;D

[geeves]

$50 each isnt unheard of for private sales Double that at a wreckers at least

so best to syick with a 2nd hand of auto hubs?? and how do they worka are the electric or vacum ne 1 got any info as wouldnt mind puttin a switch on them

[geeves]

Its all internal If the axles are driveing then the hub locks in that direction then if you select reverse they unlock and relock the other way. Auto hubs are cheaper because they do have maintenance issues and the fact that they unlock when a direction change is needed can be dangerous in some conditions ie failed hill climb. If you dont do serious 4wding auto hubs are fine.
Normally sticking hubs can be fixed with nothing more than a full clean and regrease. Be carefull dismantalling them as several parts are spring loaded and put them back together the same way with a healthy coating of grease but not too much.

I have a pair of good auto hubs from a '95 Bighorn on the North Shore if you want them.
I changed to manual ones as I didn't like the idea of the potential unlock problem described above.

well i might also go to manual hubs too then so manual an auto hubs will change easy?? and is it all pretty self explanatory or should i buy a book ??

The swap is pretty simple. You can check out the front wheel bearing replacment doc... just don't need to go as far in... www.clubisuzu.com/images/PDF/repairs/wheelbearings.zip

It's the best mod you can do to your vehicle...."Bend down on one knee, if your hubs say 'Auto' they are stuffed" - Credit to someone I forget on 4x4wire.com.
I couldn't believe where I could go with manuals, that autos wouldn't let me when I changed... they fail under load everytime.
Want some autos? you can have mine for free, they arn't worth anything

[slightlydodgy]

That was $50 the pair. I just winged it to change after reading an article on planet isuzu or was it the old 4x4wire.com tried to find it for you but that was a while ago Try these two pages for dissasembly and assembly obviuosly ignore the bit about spindle bearings

www.autozone.com/addVehicleId,2322001/initialAction,repairGuide/shopping/repairGuide.htm?pageId=0900c1528006290b www.autozone.com/addVehicleId,2322001/initialAction,repairGuide/shopping/repairGuide.htm?pageId=0900c15280062920

These auto zone pages are quite good for basic stuff

yea sweet yea think ill go to manual as past isuzus had manual and went anywhere this one got auto and not so flash so definatly go to manuals a think cheers for info will let you know how i get on with swapping them over

[mighty trooper]

also is fitting manual hubs pretty straight foward im an auto sparky so am mechanicly minded and understand how it all works but just havent done much with hubs before

[geeves]

Read the above links and all should be easy. Much easier than changing a diesel isuzu alternator

[mighty trooper]

well i aquired some manual hubs from a dude off trade me and swaped them easy as just needed those spacers machined up and on they went cheers for the advice guys

[geeves]

Spacers?
What brand are they?
Factory ones are Asin

[James W]

If you are adding spacers, be sure to get the end float right for the CV shaft seal in behind the hub to avoid water getting in and duff bearings later.

Cheers :-)

[mighty trooper]

yea there is a link on the home page just printed those measuremants off an got the engineer to machine them up an banged them together no worries perfect fit

[monty]

Hi, if converting from auto hubs to asin free-wheeling hubs do i require the spacer, just after i pulled the auto hub there was an awfully big space on axle to circlip on end of axle.
Thanks
Neil

[James W]

yep, if you don't have the spacers the CV shaft/axle will float big time... possibly even disengage off the splines.
See clubisuzu.com/images/PDF/modifications/hubconversion.zip

and be sure to add shims/washer/spacers or adjust the spacers to get the end float right so the rear seal does seal.

Put your palm where the c-clip goes and push the shaft... and push back from behind where the CV boot is... and see how much slop or end float there is when you are finsihed... you want a little, but almost none detectable.
