Pierre se patrol so 3 jaar terug:
Die eerste Patrollie in RSA met full air suspension. Hierdie is egter so bietjie langer as myne. :salute:

Daai fotos wys een van die Patrollie se enigste probleme baie goed uit. Die agterkant kan flex soos min klas A voertuie van kan droom, maar die voorklant flex omtrent niks. Dit is baie maklik om die agterkant so te laat fleks, maak jou anti-sway bar los en sit lang shocks in. Die springs gaan uitval maar jy kan hulle weer terugsit.

Vir die voorkant moet jy ernstig mod om enige voordeel te kry. Drop bokse help om die padhouvermoe weer reg testel na 'n lift en help om die flex weer te kry soos standaard maar die agterkant is so los dat die voorkant net nie saamwerk nie. Daar is net 2 oplossings vir hierdie probleem. 'n X-link of baie langer radius arms. EK gaan albei opsit.

Hi Pierre and welcome. It is great to have you here and I look forward to having the benefit of your insight.

I agree that the leading arm type suspension employed on the front suspension of coil sprung Patrols has very high roll stiffness even with the anti-roll bar disconnected. This high roll stiffness fights flex and the stiffness increases rapidly as the axle roll increases. The cause of this high roll stiffness is the fact that roll deflection of the axle is only possible through deformation of the two rubber bushes that attaches each leading arm to the axle housing.

Drop boxes can restore the suspension geomtery of a lifted vehicle and obviate the need for caster correction bushes that are stiffer than the originals, but would not be able to improve flex over the original.

Longer leading arms will improve flex because less bush deflection will be needed for a given axle roll deflection and this means that less of a countering moment will be generated when the axle is subjected to roll deflection.

Could you please describe the X-linkage and how it works.

There are other methods of getting the front to flex, 5-link or Superior Engineering's replacement arm that has a extra bush in it. There are very very hot debates about which is best when and where and how it affects squat and antisquat and torque transfer into the chassis etc etc. Outerlimits and Patrol4x4 are full of these discussions. Here is a link to the X-link home.

I am of the opinion if you are going further than the standard 2" OME or TJM or similar lifts, pay careful attention to the front. You are going to loosen up the back at the expense of good offroad performance. I bet you are going to end up connecting the swaybar in the back again because the car is going to feel like it wants to go-over in serious cross axle climbing situations. I did.
