AVM 451 HUBS

[russdog]

Can anybody tell me if AVM 451 freewheel hubs will fit my 1996 disco 1 with steel wheels. Any info will be greatly appreciated. Thanks - Russell

They should, the 94+ defender fitment use the same hubs and axle. But why?

Agreed, why? The drive shaft, the diff and the axles will all still be turning...... You might reduce some wear, but it would be a seriously small reduction. You're not going to get any steering back, the discos have a better turning circle than most 4WDs.

I can only see it as just "spending" money. What are you trying to achieve. What is your end goal?

Won't you have to lock the centre diff if you fit free wheel hubs?

[russdog]

I'm going to rebuild the transfer case using an Ashcroft part time 4wd kit, just concerned about the drive flange thickness of the AVM 451 hubs. My Disco is 1996 build I think it has thin drive flanges ? I'm trying to get conformation of their fitment to my vehicle.

Thats my understanding otherwise there will be no drive at all.

He quotes he is using a Ashcroft partime 4x4 kit ;)

And now we get back to the actual benefits of free-wheeling hubs versus the advertised benefits of free-wheeling hubs.

Advertised benefits Lower fuel consumption - has anyone found this? I haven't.
Lighter steering. The disco already has power steering.
Disadvantages. Rover diff not designed for weight of Disco when using single diff.
stationary drive train - adverse wear on prop shaft splines in single plain.
lack of lubrication to swivel bearings.
inability to engage 4WD in an emergency.
protruding FWH risk of damage when off road.
Unable to use LR alloys on vehicle with FWH.IMHO not worth the cost, you'll never recover it.

Other disadvantages:
Have to get out to engage 4wd (this is never in nice clean conditions).
Anti-squat effect of front suspension is lost, result is nose lift acceleration.
Cornering grip is diminished.
Acceleration grip is diminished.
Traction to move heavy objects (like trailers) on hard surfaces is lost.
Tyre wear becomes very uneven.
ABS on the front axle won't work.

Fulltime 4wd is one of the best things about these landrovers. Why would you want to ruin it?

Thanks for all the advice , but still no one has answered my question. WILL THEY FIT ? DO YOU KNOW SOMEONE WHO HAS FITTED THEM ?

[Lotz-A-Landies]

Sorry unfortunately. No I don't know if they will fit or anyone that has fitted them, but I have only been driving/owning Land Rovers for 45 years and owned Range Rovers Discoveries and Defenders for 33 years. That about says it all.

My first reply gave you all the information we had.

I don't know anyone who's fitted fwh's. Just like I don't know people who've fitted chrome 20's.

[460cixy]

Try Ashcroft they may know

[russdog]

Thanks 460cixy for your non bias sensible reply. Regards Russell

According to the AVM site the 451 will fit your D1. Products AVM (http://www.avm.com.br/products4.htm)

I still think you're being unwise, but if you do it, I would advise you seriously consider fitting a Salisbury rear end off a pre-2003 defender and regularly run the front drive train, even with the front hubs disengaged just to lubricate the front end.

False brinelling of the bearings should also be considered.
