Thread: Maxidrive Non Lock

I might not have standard Maxidrive locks, but both front & rear have a dash light to indicate they are engaged. No tearing around until they are

Very common for them to have problems engaging and disengaging. That is why I went with ARB.
I have been told it has something to do with lubrication in the actuating piston area.

Mine sometimes takes a while to engage - moving slowly forward and turning the steering wheel from side to side usually makes it go in.

There is a method described in the Maxi Drive manual of engaging when stationary. Some sort of double de-clutch technique - I'll check tonight.

Yeah, you have to watch the green light and do a few "Supercar tyre warmups" until it comes on. I think its more like the dogs aligning than sticky pistons. I would be surprised if ARB's were not the same as certainly Detroits do it sometimes when taking off , giving a big BANG.

IME it isn't common at all to have problems with them engaging or disengaging, just that it takes slightly longer than an ARB (due to the lower (equivalent) air pressure used), and the light only lights up when the locker is fully engaged.

If the light doesn't come on within 1-2 seconds of engaging mine, I turn it off and on, and that does the trick. Disengaging is no problem unless you are doing a tight turn.

If you have a serious problem then you either have a bent housing or trwisted axle.

You just want to knock anything I say. So go for it.

I go out regularly. About half of the vehicles use to have maxi's and half ARBs. The ones with maxi's continually had problems with either getting them to engage or disengage. It was a very common issue.

Not at all, you obviously just hate people disagreeing with you.

Your experiences are obviously different to mine. I have an MD locker, as do many people in the LROCB which I was a member of for many years. I can only recall one problem, when a (self installed) MD stopped working because an airline melted (too close to the exhaust).

Front MD lockers can be quite slow to disengage at times.

Can't say I agree. Never seen or heard of this until Greg's problem.

Unless you're expecting instant engagement. I'll bet your ARB crew think its engaged coz the light comes on... Maxidrives could be wired up that way - problem solved? Nope.

As mentioned you need to flick the switch well in advance to allow the dogs to align themselves. No big deal. Similarly, they won't disengage while there's any tension on them.
