I understand it's the shock absorber that was changed and maybe the air bag too.
Graeme reported on relative performance a few years ago.
Based on that and other feedback I decided to stay with D4 version, ie BWI

Probably right but my order also included a LCA kit and I preferred to keep the value of individual orders below $1,000 hoping to avoid extra customs duty and/or gst.
I realise the old $1000 o/s gst limit is no longer in place but sometimes this tactic works, sometimes not. It worked in this instance as nothing extra was paid.

PS ... Advanced Factors state on delivery options page: We cannot offer prices including customs clearance, you are responsible for local duties

Edit- oops see now this is wrong but can’t see why the difference would matter as the rest of suspension is the same except for AMK compressor maybe.

There was a big difference in the dampening settings.

Probably linked to the Moose Test and move to 19” wheels to stiffen it up which is not to say the previous version weren’t just as good mechanically or better from a feel or comfort point of view.

In any case there should be no material price / weight / size difference as dampening is just shims inside changing the oil passages ever so slightly.

First I have heard of this in Australia as yes they can be a bit reluctant but not stuck like the UK cars needing cutting. An air hammer gun is a cheapish tool ideal for this problem also.

Have you done a lot of beach work?

Possibly. Having had the old boys D3 for quite a while before I got the D4 I prefer the slightly firmer D4 ride.

As others have said, it's not really hard, just the hardest part of this job by far. The rest is so easy.
Personally. They are not expensive and they save you flogging the cast arms. I'm all for handy pretty tools. But that's just me. I bought a good priced one the other day but was too small for the joint itself. From memory it needs to have a jaw opening of at least 28mm. Might be a idea to measure first. Most I see are around 20mm we need them bigger. The smaller one I bought in the bargain bin at Bunnings will do tie rods etc

So no real world difference then.
