free wheeling hubs

The ones i am looking at putting on are brand new and still in box the brand of them are ORA. Have you heard if these are any good?

Do you know why the automatic hubs play up? I am having trouble with my front diff, when in 2wd turning corners at times there will be a clunking noise from the front diff. My car is fitted with a lockrite diff lock. Do you know if anyone has had this problem or anyone I can talk to about this.

JT,
Never heard of ORA hubs, sorry can't help you there. When the hubs are stripped down they have to go back a particular way, I think if you get them 90 degrees out they go back together but wear quickly and eventually fail in a big way, cost my mate a new drive shaft I think.
I didn't think it was to good to have these auto locking diffs in conjunction with the auto hubs, they lock and unlock as you accelerate and decellerate, unload and loading the diff causes a lot of shock to go through the drive train which causes wear. The occasional clunking noise might be something else rather than the diff, could be the knuckle joints worn or something like that.
You can check the backlash by putting the drive train in gear, jacking a front wheel up and rocking the wheel backwards and forwards listening for clunks.
Very hard to diagnose things on line, a lot easier to sort out when you are actually there if you know what I mean.
I hope some of this maybe is a help. My opinions and views as usual.

Matt when I say it is chattering I mean some times it makes the whole front end shake and sound like the gears or something is going to brake. But it does not happen all of the time only every now and again.
