Thread: VB Air Suspension and Anti Roll Bars

Thanks for that info.

One of the other questions I was going to subsequently ask .. more so for your purposes.
If the system is ECU operated, then there must be a way for the ECU to respond to a turn(assuming an accelerometer) taking into account vehicle speed.

Considering that it's auto levelling, couldn't imagine that it'd be hard for the manufacturer to tweak the response of the system to counter the excessive roll you're trying to alleviate.
Have to asked the question to the distributor or manufacturer?
If they can provide an uploadble solution, saves you needing to muck about with more anti rollbars and suchlike.

Also, I've been doing more and more reading up on poly bushes for a long while now .. not so much to make a choice, more so to find out as much info as I can.
I fitted them to my RRC some 20+ years ago, and loved them then, and have no problems with the few I've fitted to my D1(shocks, stg damper, panhard, and whatever else).
I won't install anything else, except if I 'had too'. Can't stand the usual suspension bush design, and fitting the split type Nolathanes is the easiest peasiest job .. so I've already made my choice.
But I still do more searching about more info/products/feedback(even tho I know what I'm going to do).
No rush, suspension in good nik, have some bits, still need to get some other bits.

But, I've read many posts where people have replied that poly bushes had ruined their ride, made it too firm, less articulation .... none of which I ever found in my RRC.
I only experienced much more durability(close to infinite in my case), and ease of fitment(not needing a press to fit them).

Could this be another option for you to combat the roll/sway issue you now have.
Maybe search up for those poly bushes that many folks complain about with the harder ride/reduced roll .. etc. and maybe fit them in place of your rubber suspension bushes.
The likelyhood is that at some point in the future those rubber bushes will need replacing anyhow ..

FWIW: back with my '79RRC, I reckon I'd go though a set of front radius arm bushes and the rear chassis mounted trailing arm bush every year, without fail.
But I was a high klm user back then .. min 70K, a few times 100K in a year.
Had to do those bushes so many times, I really should have got a hold of a 20T press to make life easier on myself .. I just used a local shop that used to do it cheaply for me.
(one other product I did try tho before the polys was back then the Rangie Spares modified chassis end trailing arm bush. That one lasted at least 2x what the original did, but still did wear out too.)

Anyhow, after maybe at least 4 or 5 sets in as many years(or close to it) .. I had to look around, and I was told of Nolathanes poly bushes.
Thought anything had to be worth a try, and when I saw the split bush - metal tube design, I was sold!
No time to fit, and just for the hell of it, after I fitted them I removed one front radius arm to be sure they were as easy as they seemed!
Ended up doing 200-300K klms on that set with no issues, and most of that was gravel/dirt type roads central aus.
So durability for me was without a question infinitely better. RRC was completely rusted to high heaven, un reg, 650k klms, needed too much work to keep it .. so was eventually got rid of.
So technically those Nolathanes outlasted me!

Therefore, just thinking of a different approach to your current issue .. poly bushes(to start with), if they can't help .. maybe then look at stiffer rollbars or shocks or whatever.

Sorry for making a tangent to this thread.

Back in 2013 I purchased an AccuAir elevel kit from the US for my Defender 6x6 so the rear axles could load share. Subsequently I was informed the eLevel ECU (AA-EC4) that came with the kit did not meet Au regulations and I had to acquire the AA-EC4-AUS ECU. I acquired the -AUS ECU from AirBagMan who also supplied the front axle kits. The AA-EC4-AUS came with instructions to modify my US harness to match the -AUS ECU. In the ensuing years I have lost those instructions, AccuAir US went into Chapter 11 bankruptcy and was purchased by another company without all the records and Air Bag Man no longer deals with AccuAir. I have contacted numerous vendors in Aus and the USA who mention the AA-EC4-AUS ECU on websites but none, including AccuAir, are able to provide the information I need.

I NOW HAVE A PROBLEM.

The AA-EC4-AUS requires an interlock signal from the e-brake (hand brake) to prevent height changes while the vehicle is in motion. This wire is coloured BLUE in the -AUS harness.

While a technical schematic would be useful, all I really need is an image of the back of the 16pin plug in the -AUS ECU.

If anyone knows of someone who has the AccuAir eLevel system with AA-EC4-AUS ECU in any vehicle in Australia an image of their plug back would be great.
