Hilux auto hubs

Thanks for your response.
I can see underneath the car that there is an elctronic mechanism at the back of the transfer case. So this means the front axles or diff are not turning until the transfer box is engaged by pressing the button. Rotation of the diff and axles engages the hubs automatically? Is this the small clunk you sometimes get?
I wish there was a site with diagrams to show how the front hubs work.

Hi Scooby,
What is involved with changing the hubs to manual? Where would I get the bits? Could I do it myself?
thanks

Hi Twinkles,
I used AVM hubs which I purchased from ARB. You could also get locking hubs from the wreckers, just make sure they have the same number of splines as your axles. Easy job to do, the hardest part was unlocking the cones on the hub bolts, a brass drift and a large hammer did the trick.
All this is explained in the manual. While you are there check / replace the front wheel bearings.
I also permanently locked the ADD unit on the left front axle. Do a Google search for "Disabling ADD". I found a site from America that explained what to do and included pictures.

Thanks so much Scooby. What manual are you referring to?

Sorry, should be more specific. The manual I was refering to is the Gregories for my model Hilux, it explains how to remove hubs and replace bearings etc.

I can't seem to find the site you refer to with explanation and pictures for disabling the ADD. Would I be able to do this too? Is there any help in the manual about the ADD?
My wheel bearing have just been repacked at 40,000km, so expect them to be perfect.
Thanks again. I'm going to investigate costs.

Another question! Why bother with locking the ADD into the 4x4 position. Why not leave it as is and fit manual hubs?

You can leave it and fit manual hubs. All will be reveiled in the above website.

Thanks again Scooby.
I had a 99 turbo SR5. My daughter has it now. I might put the manual hubs on hers too. It's done 217,000km and going strong. Actually goes a bit better than my 04 SR5 turbo. Probably because it is not as tight.
I'm putting a Lokka in the front and 2 3/4" Beaudesert exhaust including new dump next week. Eventually new suspension with 50mm lift. Have already cruise control, alloy bull bar, towbar, tub liner, TJM canopy, snorkel, 2nd set of wheels with BFG muddies. Thinking about dieselgas.

Hi Twinkles,
Your daughter's Hilux, I presume is fitted with an aftermarket turbo. What brand, did you fit it, have you had any problems with overheating or clutch/ gearbox?
I would love to fit a Turbo to my 99 SR5, been quoted approx $4000, it's tempting.

My daughters Hilux would have been the earliest turbo diesel from Japan to Oz. It was manufactured 12/99. It was first registered 2/2000 and I bought it late 2001.
The 1KZ TE motor. I think it has a cable from the accelerator. Looks the same as my motor.
I couldn't find an AVM hub listing for my car at 4x4STORE in Qld, so I looked at the site in Brazil where they make them and got the the part number 413 for the type of hub. I then rang ARB Dandenong and they said they had no listing for the IFS ADD models. I told them about the site in Brazil and they said they had sold some to people but never fitted them. They would have the 413 in stock.
I then rang the TJM guy that services my car. He rang ARB head office in Melbourne and they told him not to do it and it would give problems.
I read the 2 sites you gave me and think ARB don't know what they are talking about.
Is the 413 the one you fitted? Your IFS ADD vehicle would have the same chasis as mine. They didn't change it until the current model as far as I'm aware.
This is the site in Brazil:link text
I've also got onto ARB in WA as this must have been where you got your AVM hubs. Spoke to a lady. Very helpful, she got onto someone that had fitted them on same vehicle as mine and got back to me. She also said 413 was correct model.
I rang Goannawhere in SA who supplied my Lokka. The gent there said the 413 was correct. Good idea to fit but not absolutely necessary. Will reduce some wear and drag.
Not many people seem to know much about ADD or fitting locking hubs to them.
Thanks for your in depth info.
