FREE WHEELING HUBS

[BajanFeroza]

My Feroza does not have any free wheeling hubs on the front wheels, is there any benifits to putting on a set, I have access to a set but dont know what the REAL purpose of the FWH is, or what they can/cannot do.

That is suprising - are you sure you don't have automatic free wheeling hubs?

[HotFourOk]

Yeah, they could be automatic ones...

You could buy manual locking front hubs which are seen to be more reliable than auto locking ones (if this is what you have), and you know when they are locked/unlocked.

Without any locking hubs, you wont be able to have 4x4 available at all.

According to the manual there are three types of hubs... Manual - you have to engage/disengage, auto - they in theory lock and unlock themselves and fixed - the front diff / drives is permanently engaged.

Fixed hubs loose a little power / economy because the front diff is always rotating whereas the unlocking type disengage the front diff when not required.

This doesn't mean you are always in 4wd, just that the front diff is rotating which costs a little.

IMO manual lock hubs are the best choice for a roza.

Ah yeh, I didnt know that Roza's came with fixed front hubs.

I think the drag would be negligible on the drivetrain... but wear over a number of years could be a factor.

For your application, permenantly engaged front hubs (or drive flanges etc) would be fine (as long as you dont go trying to use 4wd on the road). But for applications where modification has been carried out, these can induce vibrations and other strange habit in a vehicle, e.g. constand 4wd landcruiser with big lift can develop vibs from its front shaft, so fitting a part time kit would be worth the effort to retain road manners. As for you roza, i would guess you have auto engage hubs. These are pretty good, but can have faults that cause them to not lock, so if you are worried, or experienceing this problem, then manual hubs are probably the best bet. Does your transfer have 2H-4H-4L, or does it have a 4wd button and 4H - 4L on it. The earlier rockys had manual hubs, and a 2H-4H-4L transfer, while the later ones had a button for 4wd that engaged the front drive in the transfer, and a lever to shift between H and L range. Not sure if roza has this system as well, or if its front is permenantly locked in and the transfer just shifts between 2 and 4 wheel drive.

Layto....

My Feroza has 2H-4H-4L on the 4 wheel drive stick, how can i check to see if the front hubs are automatic or other ?

[ferozamaniac]

Here is a picture to see what is automatic hubs and what is manual hubs. Now if you have the manual hubs then you have 5 manual gears 2h 4l 4h. If you have the automaic you may have the 5 manual gears 2h 4l 4h or the automatic 4 gears box.
If you have the automatic gear box then you should place automatic hubs if not you could use the manual hubs where you will never have a problem if your front wheel are working.

And the fixed hubs look nothing like either of the above - they are a simple flange with a small protrusion in the centre.

I have a picture of the hub but i cant seem to get it onto this post.

That seems to me like what mine are, but someone will post my pick for me and hopefully you guys will be able to sort me out.

Well my friend as far as i see you have the ones than never stop rolling the front differencial. Here is a picture of his feroza

[chev28]

They're the fixed ones alright.

It's not critical but free wheeling hubs do save petrol and wear. Depends on the cost as to whether it is worth it for you.

There is heaps said on the topic, just google "free wheeling hubs".

[BajanFeroza]

well, thanks for all you help.

As I dont really drive this jeep on the road tomuch I guess there is not much of a need to change them.
