Front Hubs

[rustic]

cheaper? less to go wrong? Did I mention cheaper?

Same reason they took the grease nipples off the front UJ's and slide on the front prop shaft. Save a few pence here and there.

They found that the front UJ's never failed under warrenty, however they forgot that with Auto hubs they rarely turn, so they removed the nipples.

When they replaced the auto hubs with fixed, they forgot that rotating things need more grease, but wanted to save 30 pence per vehicle, and remove one more service item...

Mine has the auto hubs, and the grease nipples on the front prop shaft, did I mention all my bits are the original bits, UJ's ball joints bearings etc.
Not bad for 17 years of ownership. :bow:bow

Most manufacturing companies have prizes for the workers and engineers, that if they suggest something that reduces the cost of production, people can win prizes.

I wonder who won the prize for the fixed hubs?
And how much did the idiot win for removing those grease nipples.

Also who suggested putting a cheaper rear diff in that also used less oil...?

Wow must have saved a total of £1.00 per vehicle on that one.

I suspect the fixed hubs was more to appease the sales teams. None of this 'reverse after you disengage' nonsense. Makes it looks much more like a simple 'on demand' 4x4 selection and therefore makes an attempt to make old technology seem much more up to date when actually it's harking back to Series Land Rovers!

Just been reading other threads on this and trying to get my head round some things still, I understand the difference between autos and manuals now etc however, on the later Terranos with manuals if the manuals are always engaged I presume they are always 4wd, if that's the case why don't the suffer the same issues as us with autos in regards to wind up in the transfer box on tarmac which I thought caused damage?

I don't mind sounding stupid so long as I find out lol, you'll never knoq if you never ask

Later hubs are "Fixed" so they are always turning the front transmission but not being driven by the engine. They don't suffer windup in normal use as they are not connected to the rear transmission until 4wd is engaged via the selector lever.

Manuals can be the same too when left in the locked position.

Both will suffer windup if 4wd is used on a hard surface just like auto's do.

Understood so how are Land Rovers different, for example why do they have a "Difflock" and what does that do?

LR's have a centre diff fitted to the G/box which lets the front & rear axles rotate at different speeds which stops trans wind up & means it can be driven on the road with out any wind up, when you select the difflock it locks the centre diff so both axles get the same amount of power just like a Terrano does as it doesn't have a centre diff:thumb2 Hope this makes sense to you. OH BTH very early LR's didn't have centre diffs & had a transmition set up very much like the Terrano's ie free wheeling hubs & 2H, 4H & 4L on road they had to be in 2H

Stored in the memory banks under 4x4 thanks for the info guys

So my 04 terrano has fixed hubs? If so is it possible to fit fwh so they free wheel rather than waste energy time and money turning the whole job lot of wiggly bits when in rear wheel drive?

Yes

 

[Blocky10]

Yes

Sweet. Thanks for that.

 

[jims-terrano]

And as I've discovered they do sap the energy. My newer truck doesn't have the same go as my old one but as soon as I lock my manual hubs there's not much difference.

Obviously I'll have to change the wheels to fit fwh's ad there's no centre hole in em. Is that right?

Yes you would have to are you on 17" alloys

 

[Fez_uk]

I don't think it's as simple as that, as stinka tried and has some issues.

Yes they are 17's.

Oh. I'll research the hell out of it before making a decision. Bought it for towing a caravan so will be spending most of its life in 2wd.

The other good thing about manual hubs is that if you're towing something heavy you can engage 4L with your manual hubs 'off' and it will give you 2wd in the low box :thumb2

One of my next jobs in fact is to convert the Trol's auto hubs to manuals - Trol hubs are auto with a manual override so if you remove the 'auto' bit from the hub they become manual only. Quite a common mod over in Oz.

Auto hubs are a direct replacement for fixed hubs ive done it and have pics:lol

That's handy. Is there a reason you used auto hubs other than not having to get out?
I was hoping to fit manual hubs because their cheaper and will not be used much.
Also, can I see the photo's?

Your prob better with manuals but you will need to change your wheels.
No hubs

Fixed hubs

Brake rings fitted for auto hubs

Note that the short studs that were used for the fixed are removed and the long skt cap screws are used for the auto hubs
Also note that the driveshaft has 2 grooves one is for the fixed hubs and the other further in holds the brake rings for the autos.
As long as you purchase the complete hubs they are completly interchangable:thumbs
