Thread: Gazza's ARB has issues

i have seen the dead centre, and thought about it for a while,
can't see why it all fell apart, but it would seem that the bolts holding the centre together failed and fell out, possibly, allowing the cross shaft pins to back out into the bolt holes of the carrier cover, and allowed the shafts to move out,
theory onlt, but i will lookinto it further, still don't understand why it all came loose, this was in the heep front diff, and there is no way the cover can move away fron the centre.

For those who are following this thread with a mind to not having an ARB.

You may now go down to your local ARB and Bear down on them with Furious Anger and tell them just what you think of their locka held together by six small bolts.

Here are two alternatives; I have found Suits Salisbury at least, not sure about Rover, probally soon.

I personally like the Eaton because it is a related company to Detroit who make great Lockers. For a Salisbury Rear (IMO) there is no other choice than a No Slip Detroit.
The ELocker looks nice and strong in the pictures and simple to install, no housing modifications, except a hole for the wires.

This is whats left of 6 small bolts and 3 pins, note the elongation of the holes in the cross pins.


The Hemisphere used to be round and fitted the top snugly, opps.

Gaz,

Surely if the bolts came loose and fell out thats not the fault of the locker? What would you expect to happen if the bolts fell out?

How many and what size bolts woudl you prefer? If 6 fell out whats would have stopped 8, 10 or 12 doing the same?

Here is a picture of the eaton eLocker, I like it because the load bearing hemisphere is held togeather by the very large very strong bolts and flange that hold the crown wheel on.
Better design IMHO.

Maybe, but what would happen if the bolts fell out!?

the real question is why the bolts came out, and this was a diff centre that was not new, and i put it together, and torqued the bolts to arb's specs, and locktite'd them
i actually don't think the arb product is at fault,perhaps loaded past it's design limit.
and i really need to look at it further to establish why it came loose and worked the bolts out, like arb have made thousands of these, so why don't we hear of this more often.
my arb in my land rover is the same, although not that older design, and not worked as hard perhaps, and it also has been pulled right down and reassembled by me, so mine isn't loose, why did gaz's go bust?
perhaps it's a heep [jeep] thing?

My arb front locker is identical to Gazzas (10 spline RD03 type) and so far it's been trouble-free and I was told that it could be problematic as it had a hard life. I just fitted mine up change the oil once and it's been good for the 8 nmonths I've had it.

The rear is the newer RD128 design and that has been superb (should be for the $$ that it cost ). I've heard of the same issues you're having a couple of times but it's not something that is commonplace.

Hey Harry, This was the locker that was bought second hand wasnt it. Could its past history be suspect
