Then your missing the point, let me do a simple drawing with a compass and get it up on here so you can see why it wont go straight.
Will it then point North??? 8) :wink:


Depends if he drops it :P

Ok, the arc on the line has the least lateral movement, now look at what happens when you lower the mounting point. I'm trying to keep this simple Dandy to make a point about axle movement.

It will cook your tyres as they will scrub more (be pushed/pulled in and out a bit like the Hokey Cokey) :roll:

TGP is spot on with the theory but if you fit shorter springs then it will raise the axle point - and if the standard setup has the chassis point higher than the axle then fitting lower springs would bring the panhard rod to more horizontal #-o - I'll have a look in the morning at where the standard setup lies in relation to the chassis point - interesting thread =D>

Ahhhhhhhhhhhhhh thankyou :wink: :wink:


I know a couple of scrub####, if i wrap them around my wheels will they go further :lol: so i take it if my rear tyres are good and i not had a prob with excessive wear then i should be ok



I agree with dandy interesting :!: lets see how long before i get confused :roll: was always better with me hands

So what your saying is right then adjustable panhard is the way forward, 1: it will centre my axle 2: my arc will be smaller so less cooking on those tyres.

Or have I misunderstood you.

Like I said Dandy I was trying to keep it simple to show how the arc changes related to axle movement. If we start talking about if the pickup point is at the roll centre point and its affect or relation to suspension design everyone is gonna fall asleep. :wink:

Hmm I used to fix bits of machinery so thought I would get this one, but no I'm lost. However, I have just had the bingo, bango lowered by 40mm with the springs from bell hill. I feel like the handling has improved and I don't have a pull to the right. Does this mean that all is well and these problems only occur if you have your van lowered beyond a certain point, or is it just happening to a lesser extent?

The reason mine is pulling to one side is cos I had the tracking done while the rear axle is out of alignment. They tracked the front wheels from the rear ones, cos the rear is out the front is now out :shock:
