First time I have really looked at this properly, but if you look at the  JimnyBits , quick disconnect. It looks like the kit is made of two tubes that fit over the sway bar by a good amount and the mounts are up close to the tube ends, so they should move apart.
Also with the grease nipple being there, I'm guessing the actual joint is a bar and sleeve affair that rotates in itself. Not as simple as cutting the bar and welding plate to the cut ends.
They also offer a ready welded one, don't know if that is on exchange basis?

Would like to know if the Gen3 and Gen4 sway bar is the same part number?

Unfortunately they are not the same on the Gen 3 and Gen 4. They are very different. The Gen 4 has a much thicker bar.

I think from memory that the gen3 was variously equipped with 3 different sway bars, early ones being thinner, I want to say something like 19 or 20mm diameter then the later ones were 22 or 23mm and finally the diesel had a 25mm diameter. I looked into the diesel variety when I was chasing lap times but I wasn't able to find one at sensible prices. Now I am inclined to see about a thinner one to free some articulation without hassle of a disconnect. The issue though is that really all this is just tweaks on the edges of the actual problem. Unfortunately with a Jimny the relative weight of the unsprung elements is quite a high proportion against the overall weight of the car so the ride is never going to be perfectly smooth. I noticed that when driving Leviathan where the weight of the unsprung elements are a lower proportion of the weight of the car, she just glides over irregularities in a way that Temeraire simply can't.

Thanks, I thought that might be the case, otherwise I'm sure Jimnybits would have listed the Quick Disconnect for the Gen4 also.

The Gen 4 is obviously softly sprung, and relies on the sway bars for on-road stability.
I would be very careful driving the vehicle at speed on the road with the sway bars disconnected.

There was a case some years ago on the Land Rover forum where someone fitted a lift kit and associated aftermarket dampers to a Defender 110, but they removed the sway bars for "better off road articulation"

On the way back from getting these parts fitted, the vehicle got into a side to side swaying motion on the motorway and ended up on its side in the outside lane.

The driver was OK. There was some talk of suing the specialist who did the suspension.

Normally, removing the sway bars wouldn't be an issue on a Defender, as the standard springs are very stiff.
In fact the base models aren't fitted with sway bars, they are only fitted from the factory if the original owner specified alloy wheels.

I had the side to side swaying with my gen 4 when it was brand new, but that was trying to see how fast I could get it to go. Very scary when it started swaying at 150kph.

More recently I have experienced swaying when heavily loaded, but we found the front shocks had started leaking.

Front shocks are leaking already? That should be a warranty issue. How many miles has it done?

The Gabriel HDP shocks have a 3 year unlimited mileage warranty.  I have had them in since December 2018, so they are still under warranty.
I have done around 60000km on these shocks.

Just to add, SAXJ play very hard so the HDP's has done its part. Believe me that 60000 km is more like 120 000 km's how I drive.

Had the HDP's on my gen3 for many years and again now on my gen4. Cant fault them. They are solid.

I have cancelled my planned sway bar release mod. See below for more details.


This week I put the sway bar articulation limiter back on.


Experience no. 1 : The first day of driving on tar with the sway bar replaced:

Something is wrong, the handling feels weird and it feels like I am having issues staying between the lines. The couple of weeks of driving without the sway bar obviously had an effect on my driving style.

The tarred road surfaces feel worse than they are.


Experience no. 2:  Went to see a client on a farm yesterday. Reasonably average crappy dirt road.

Not nice. I simply do not like what the Jimny feels like on a dirt road with the sway bar on. The ride is too bumpy and it feels like my tyres are inflated to about 4950 psi. Too much side to side movement. Feels like the wheels are directly connected to the body.


Experience no. 3: Short 4x4 type road I found on the way back from the client.

WTBF???!  Its bad, REALLY bad. It feels like I am trying to go offroad in something not built for it. The bumps are bad, the whole car gets thrown around left and right, rear wheels losing grip when they are not supposed to.

In short it is the opposite of fun. It is unfun.

Conclusion?

I am taking the bloody articulation limiter off and its going to stay off. I am not going to bother working on it, and it can live in a dark corner of my workshop from now on.

I will drive the Jimny like a Unimog and enjoy it like a Unimog.



PROBLEM!!!

Here I need some input from you guys: The softer suspension is wonderful and the wheel articulation is awesome.

The only problem is me:  6"1  and 260 pounds.  

When I am alone in the Jimny, the suspension compensates for my weight by visibly sagging to the driver's side.

So, I have the following options:
  1. Always have a copilot.
  2. Get a 200lb counterweight somewhere.
  3. Get better shocks
  4. Add spring spacers

I deliberately carry my everyday kit on the passenger side specifically for this reason and I am heavier than you at 140kg. On my last Jimny I did have a 15mm spring spacer for a while before I worked out that I had a matched pair of rear springs instead of a left and right of different free lengths which has the same effect.

An update after a couple of months:

I still have the swaybar off.

Replaced the shocks a while back with new Gabriels. I could not get hold of the heavy Safari shocks I was looking for, but the new shocks definitely made a big improvement.

I have done a couple of rather long highway trips in the meantime and I cannot report any issues.
