Drive quality between Gen 3 and Gen 4 LWB

[bhanganek]

Good day to all

We have a 2004 GLS, and 2012 GLS, both LWB

We experience that the gen 4 seems to ride much "harder" on all surfaces, than what the gen 3 does

We have checked the tyre pressures, according to suggested rating "2.3 bar on gen 4", versus 2.0 bar on gen 3

The tyres on both vehicles are the same, Goodyear Wrangler, and roughly same km's done so far

I have not as yet checked the difference between the two vehicle's shock absorbers, and have also not checked the thickness or length of the coils on the two vehicles

Is it possible that the gen 4 rides much harder than the gen 3?

If other coils have been fitted, how will I be able to confirm this? Is there a thickness or length difference?

I have not as yet parked the cars next to each other on a flat surface to measure the height of the mudguards

Both vehicles are standard with no extras, and running empty

Any suggestions or advice, thank you

Regards

Andries

The gen3 and gen4 has identical suspension.

If the ride is different it will be attributed to the following things (or combination thereof)

- shocks
- coils
- swaybar stiffness
- suspension bushes
- tyre pressures and brands

- the solidness of the dash and interior trim plays a big part in the "feel" of the car.

Thank you for your input

Is there a way to determine whether the coils have been changed to a more "stiff" option? Any markings, or size or length indicators?

I agree with the dash rattles, definitely more pronounced in the gen 4


Another question I have. How can I determine if the shocks are still doing their job, as they suppose to? I can check for possible leaks, but if they look good, is it possible that shocks loose their working abilities?

Thank you again
