I have the shitty standard auto ones. It sounds like hubs from what heyhey said as they have been gay lately like continuing to click after put back into two wheel drive and requiring to be hit with a hammer to come good again. It is when driving forward and seems t get worse the more I drive.

The shitty standard auto ones are most likely the cause. I ended up replacing mine when it started really clicking bad (talking bangs in the driveline) with the new Heavy Duty AVMs, no problems since (apart from installing them (my bad)).

Yeah that is a good way to desribe it actually, sounds like what mine was doing. Starting a new job soon and AVM's are at the top of my list after swivel hub seals. what problems did you have with the install if you dont mind me asking?

The hubs come in two parts and are held together buy there small tapered Torx key bolts, the tapers on them are so big and make such a large surface area lock with the hub body, when I tried to undo them I couldn't and broke all my torx bits, ended up cracking the shits and smashing them off with a 4lb hammer. Ended up finding out they have such a large taper to stop them coming out when you don't do them up full on tight, it would pay to read the instructions ;)

Yeah i replaced my auto hubs with DX manual hubs. Dunno if they were off a GU or GQ. Mine wouldn't disengage sometimes and would click.. It ended up just being some twat had filled the hubs up with grease instead of just lightly greasing them but i had bought the replacements by then so i swapped them over and sold the autos. Pretty easy to do (doesn't require a 4lb hammer) hahaha

Only time it is inconvenient is when its raining and im going on a dirt road for a short time - i have to get out and engage and disengage but other than that they have been really good.

Ohh and the time some numpty locked them while i was parked in the shopping centre carpark..

It would be interesting to know how many people have had problems with the auto hubs and haven't been manually locking them when going off-road vs those who do lock them manually when going off-road.

Well shortly after I got the GU I started locking my hubs manually and found it would go better, but then they would still click after being put into 2wd. So Dronus, is it worth pumping a little grease in to see if it fixes the problem to confirm it is the hubs?

The auto hubs should not be over-greased, just a light coating, as otherwise the auto mechanism cannot connect/disconnect properly. I'm trying to think of an analogy and the ony thing that comes to mind is a rifle bolt. Imagine if instead of just a light oiling the bolt, you coated the bolt heavily with grease, you'd find it pretty difficult to move the bolt in and out.

Removing the locking mechanism is easy. Take off the hub, flick out the auto ring mechanism (it will be obvious when you are looking at it) with a lever.

Replace hub.

Go and buy a cheap socket and weld an arm to it so you can keep it in your door sill, rather than having to hunt down the wheel wrench from inside the pouch in the back.

Get dirty every time you have to get out and lock/unlock the hubs.

To go with this thread of clunks, does anyone else get a clunky ting - sounds to be coils resetting- moving front mainly (does it occasionally out the driveway) a lot while wheeling.

Would this be due to coil caps knackered (correct term?).

This is my first coiled 4wd so unsure. Is this normal. Will do it on small or full flex.

I sometimes get that and only in the front. It's due to the coils turning/moving about in the seats and usually happens when I hit a mound too fast. It's nothing to worry about.

Nah mate as Ray said you don't want too much grease in there. I degreased mine and lightly greased then to check them before I sold them.. you could try that.. also as others mentioned try locking the hubs manually when going off road.
