4WD no more

[Yendor]

Hi all,

I have lost drive to both front wheels. Drive to the rear wheels in both high and low range seem fine. There was/is no clunking or strange noises coming from the front end when in 4WD.

I have an auto locker fitted in the front diff and have the standard factory auto hubs that have had the manual conversion done to them.

If I turn the front wheels by hand with the hub locked in, the front tail shaft doesn't turn.

I have removed both hubs and I cannot see any physical damage with them.

I marked the end of the axle, refitted the hub and with the hub in the locked position rotated the wheel 180. I then removed the hub and the axle was still in the same position it hadn't rotated.

If I spin the front tail shaft by hand both front axles rotate. This was done one wheel at a time.

I think my problem lies with both front hubs. What do you think? am I going about checking this correctly? My concern is my checks are being done under no load.

Is there something else I should be doing?

Thanks in advance for your help.

Can you still spin the front tailshaft with 4wd selected and the handbrake on?

No the tail shaft is locked when 4wd is selected.

Ok well it is sounding like the hubs are the issue. Although sttange for them to both go at the same time. Have you had any work done recently on the front end?

The last work done on the front end was converting the hubs. It's due to have the wheel bearings done but that hasn't been done yet.

I'm wondering if one hub was already gone and I didn't realise as the locker would keep drive to the other wheel??

Maybe. It easier enough for you to swap the hubs from side to side?

Probably wont do anything if they are stuffed I suppose.

A mate had after market hubs installed, they were the wrong ones for his car.
They only just engaged so when tested by the installer appeared OK, but under load they slipped and of course had no drive.
Unfortunately he found out on a 4WD hill in the Kimberly, no funny at all!

It's easy enough to try.

That always the way, when you need something the most is when it fails. I was trying to do a hill climb out at the Springs 4wd park.
