( as it only took half an hour to rectify )
I bought some Manual hubs, One vitara set and a set of Superwinch brand ones.I only got them for spares as I do have the the Aisin one fitted already.
The Superwinch ones were not engaging and the vitara ones were stuck.
So I done what I thought was right, stripped them and re-filled them with grease."Bad move"
Then I noticed that the velocity of the grease was stopping them moving correct as it was causing friction and stopping the Lock and unlock working free and easy.
I read on the internet that on NO ACCOUNT must you use grease in hubs and only to use a light coating of oil.
So I did and now both sets work fine, they click in and out great.
I took all the grease out by stripping the hubs and cleaning the whole lot with petrol and removing bits of rusty stuff with a wire brush before re-oiling.
Not a lot can go wrong with manual hubs, they are all very basic and easy to strip and build.
The Aisin type are fool proof and made strong, The Superwinch type are similar ( Strong made and easy to work with )
The Vitara hubs are well IMHO are put together with plastic, even the bit you turn is plastic, so I would tend not to recommend the Vitara ones.
Kirkynut's advice is right !
Cheers
Yes I appreciate that but it's nothing to do with the hubs, the splined shaft is not even turning and if I operate the hub in my hand it locks and unlocks no problem (Aisin).
Just to add..you are right. If the Hub locks and unlocks in your hand then it is working.
You need to see if the shaft that sticks out through the hub turns the prop as if you had a manual hub on and it was in the locked position.
So if you are turning the splined shaft without the Hub attached and it does not turn the prop when in four wheel drive with just the one wheel lifted, it has to be either your shaft is Fecked or Your transfer box.
I will be honest the whole assembly is simple and with the transfer box been separate makes repair easy. ( unlike other 4x4 things )
Right in my undereducated words and grammar I will say what should happen.
I have done loads of these honest.But without been the repairer here and now it is a hard call to post anything worthy of me on here.
With hubs off...and half-shafts sticking out. Jack up one wheel ( NOT one side )
So now we have the FRONT wheel off the deck !
Turn the shaft with the vehicle in 4x4...you should now be able to turn the shaft and the FRONT prop will rotate ( you can see it as you are working ) on both sides.
If it does not then it is something else and we have already kind of eliminated the Manual hubs as they simply work or not but yours do.
But please do not worry as the rest of things it can be is quite easy to repair.
I have to dash out now as its work time but I will be following this tomorrow night. Like kirkynut says relax we will get to the bottom of it..
Sounds as though the shaft/cv/diff bearing is seized on one side.
Jack both front wheels up, and lock the hubs with the car in 2wd.
If I read you right one wheel will turn round by hand (and the propshaft will rotate at the same time) the other won't turn because it is seized.
The hub will have to come off on that side to pull the driveshaft out to see what is broken.
I reckon you split the steering joints, drop off the brake calliper and pipes then undo the bolts around the dust seal, remove it and pull the kingpins out and the hub will pull off then the driveshaft can slide out.
If it suddenly breaks, go back to the last thing that you did before it broke and start looking there
Can you hear the hubs lock when you turn them to lock? I'm not convinced both are locking.
It is possible for it to appear to lock when off the car and then not lock on the car as there may be too much drag for it to slide on the splined shaft or other reasons. I've had it.
Have you cleaned the hubs out? If not, open them up and spray a bit of WD40 in them to free them up and clear out some grease if they are over greased.
I'm convinced you have not snapped a shaft or anything like that. You'd know if the CV was gone as you'd hear it, and I doubt you would have enough grip in your tyres to snap a shaft.

The state of the hub is erelavent mate, the fact is that the splined drive shaft doesn't turn when the prop shaft does.

If both wheels are off the ground both wont turn (mine didn't anyway) the one with the least resistance will turn the other wont.
Sorry if i've missed this bit but is the prop turning when you rotate the drive shaft? or is the other front drive shaft turning when you rotate it. Get someone to check it out.
My head was done in when trying to figure out why mine wasn't working. I just locked the hubs and tried it on the field and it was all working so didnt worry about it after that.
Sorry I thought I had made it clear that when just the front nearside wheel is off the ground the driveshaft turns but doesn't turn the propshaft when in 4wd.
There is no connection between the shaft and the diff on that side so something must be broken.

I feel your frustration gromit!
I am in a world of hurt with my vacum hubs!!! I have orderd some manual ones from Germany. They fit direct and don't need adapter plates!
I hope this works but I fear it could be a halfshaft or the diff! Ouch
In my humble it sounds like u have done a half shaft! I darthlockie on here has done a half shaft and he says it made no noises or crunches etc!!
