torsion bar question

Hi again everyone!

1stly thanks everyone for all your help with my prev posts.

Now here is my new question!!!!!!

I have just put GQ spings under my NG V6 wagon. I now want to get the front somewhere similar to where the back is. How far can I adjust the torsion bars? I have already turned the adjustment 8 full turns but I can't find any difference in height. I am assuming that you turn the bolt the same direction you do to do one up... is this correct?

By the way, I got a 3 and a bit inch lift!!!

Thanks
Dean

I was surprised at how far I needed to crank those bars to get my 2". Just keep going. Also, it seemed that when cranking one side only the hieght didn't change much but when I went over to do the other side she all came up quite nicely. Trim bump stops before lifting otherwise you will end up riding on them. Harsh ride.

Should I jack the front end of the ground?

I didn't, but that might be wrong. I just found cranking some then measuring did the trick. Just involved a lot of crawling back & forth from under car. You could get a busty assistant to do your measuring for you if you have one of those available. Sadly I didn't.

As you crank the torsion bars you are trying to change the angle on the control arms, which (as well as lifting the vehicle) will move the tyres inwards. While they're sitting on the ground it's hard for them to move, so the tyres will deform and the suspension won't "sit right."

You need to get things to "settle" before you try to measure. Lift the tyres off the ground (preferably by jacking under the lower ball joint) or simply roll the vehicle forward and back a few metres.

Have fun!

If you jack the front off the ground, it will make it easyer to turn the bolts. But than you have to lower it, roll it back and forth, to check the height.
Have fun.
I had to reindex the splins as the bars had sagged and I ran out of bolt lenght.

Thanks guys for the help.

I have another question...... Some people cut the bump stops to get more height.. couldn't you just take them off? If cutting is the best way, how much rubber should be left? So far I have wound them up until just before it sits on the stops.

Thanks

On my truck the bump stop also holds the brake line. You dont want to take the whole thing off, when ever the arm contacts the stop bracket it will probably make an awful racket.

Some people have been known to throw away the existing bump stops and simply glue some rubber in place. Apparently it works pretty well until the rubber falls off - then the metal on metal really lets you know you're at max travel. :D

Good luck,

Scott
