Front Drive Shaft Update

[C-Mack]

Curious if IA would sneakily change the stock spring heights especially at the front of 2026 models to offset the problem a bit? Anyone got a tape measure handy?

This may be a situation where I willingly trade ‘performance’ for ‘reliability and longevity’…

I probably will not install shorter shocks, but I am very likely to reduce caster to 1.5° from the current 2.5° for the same reason of increased reliability. I own a lifted Jeep Wrangler so I am accustomed to vague steering.

Nobody slamming their Grenadier to avoid CV issues?

You make it sound like a side piece…

Is front axle ‘droop’ controlled by springs, shocks, or something else?

Shocks. Maybe someone can make a cheap limiting strap.

Suspension arm/axle geometry and shock length will control the droop. I was just speculating if IA would run a slightly short springs on newer models in an effort to keep the on road running angle of front driveshaft slightly lower as some sort of stop gap measure to increase mileage between failures. I doubt they’ve taken any action or made changes at this stage.

Droop is controlled by a combination of the shock length and the sway bar. If the sway bar is removed/disconnected then only the shock length controls droop. For instance, if the right wheel is fully compressed to the bump stop on an obstacle then the sway bar will prevent the left wheel from fully drooping. This is why a vehicle with a sway bar disconnect is said to have more suspension travel. The total travel is still limited by the shock length but without the sway bar getting in the way one wheel can be fully drooped while the other is fully compressed.

They need to sell this rig with air bags so we can just lower when we don't need the height and save the driveshafts from self destruction...

Most people would just pump them up fully to look "awesome" in the neighbourhood.
IMO only a small % of owners will ever articulate the suspension significantly

Starting to think Landrover was on to something with their airbags..... Maybe it was to fix the driveline..

No, it was to allow owners and children to get in the car People aren't very agile in 2026. compared to 1956.

You jest but I was recently sitting in a dealership waiting for my car to be serviced an a couple came in looking at Grenadiers. The only line of questioning from the wife was around the vehicle height for getting in and out and "can it be lowered".

Electric steps are hyooge in some countries! In fact they border on tactical.

My caster is 1.76 and steering is great but I have a longer wheelbase in the QM.
