[damianovdd]

Thank you Tony.
I think I got it. (most of it )

Here what bothers me (i told about pic) to fill up my previous post:

Settle down Scott, technical is my area mate! You answered that very well.

Tony

Yessum boss, I know my place!! LOL
Thanks mate - I googled it!!!! LMFAO!!!!!
Nah, just remembered some of the many things I paid for when I had mine done ...

When you lift a Patrol the swing of the control arms does pull the axles towards the centre of the car (looking side on). As the suspension gets compressed the control arms will push the axles back torwards their normal position.
If you want to push the axles back towards their normal position with raised suspension you can fit adjustable control arms to the rear, and drop boxes or radius arms spacers on the front. The down side being that when the suspension is compressed up the axles will now be pushed further towards the ends of the vehicle than normal.

yes.. but if you dont have longer control arms you will have rear steer issues which is bad for balance. The money saved on not getting control arms could possibly be spent on roll-over repairs.
Also,when the rear is at full extention the wheels (without longer arms) will try to drive under the vehicle thus loosing forward drive. in some situations this is a serious hinderance to offroad performance.

G'day Ben, sorry mate you going to have to give me more detail than that mate, i am not sure i understand what you mean by "rear steer"? in relation to rear lower trailing arms?

Under normal driving on a lifted car without extending the lower trailing arms the wheel base will be slightly shorter but i cant see how that slight geometrical change at ride height will be detrimental to the tracking of the car. If you mean what i would refer to as crab walking that is more an issue with the Panhard rod adjustments?

Also,when the rear is at full extention the wheels (without longer arms) will try to drive under the vehicle thus loosing forward drive. in some situations this is a serious hinderance to offroad performance.

Sorry mate, got me again? I dont understand what you mean by this at all? Are you talking about the affect on the pinion angle in this situation?

At the end of the day NISSAN designed the car like they did, when we lift it all things need to be considered and our task is to get as much lift as we want without compromising the factory angles and stresses on the drive train. There is alot of discussion about the collateral damage cause to the back of the rear guards by fitting extended Lower arms. Certainly the Pinion angle needs to be addressed but a far better approach to this without the collateral damage it to fit adjustable upper arms and heavy duty factory length lower arms.

My 2c

But i am certainly interested in considering what you have to say as i have this setup and always looking for different thinking.

Cheers MR

Damn i just bought a GU with a 2 in lift and was thinking of going for a 4 in but by the sounds of it there is a too much work involved for the gain haha

Hey Trav, nice GU IV in your avatar mate, i have a 3" lift in my GU IV but went drop boxes on the front for caster correction (Love them) and 1 extended brake line for the back and the long back one for the front and you will be right like that mate.

Ya just got to figure out why you need the extra lift and whether it is worth the cash.

here are a couple of pics of my GU IV check out half way down the page mate.

G'day all for my two Bob's worth, when i decided to go the 4" lift on my gq I looked at alot of options and what made sense to me was to buy a complete system, tried and tested (and engineered) by others. It took a bit more saving up to get a complete kit but was worth it in the long run (saved a bit by doing the install myself but not a lot) I've put the ol girl through her paces and have not found any excsessive movement rearward to the extent of damaging rear 1/4 panels, but this is an old gq! Anyway research, research, research as you are doing and also check your local regulations before you make your final decision. still scrape my inner gaurd on full compression but luuuuv the flex i got

Hey mudrunner, just out of curiosity mate, can you use front sway bars with drop boxes fitted?

Yes you can, that's what I've done with mine. You need extended sway bar links pins.
