Morning all,
A question for all you
suspension guru's (anyone actually),
The problem I have is that our Terracan has a double bounce that seems to be coming from the front end. The terracan has a torsion bar front end and live axle rear. We had the Trek and Tow fitted and it had the double bounce, we got the original refitted after some to and fro with Hyundai(& got our money back too), the double bounce was still there, but not as bad as when the TnT was fitted. Went to ARB for the OME kit and had it installed, but the double bounce is still there. The torsion bars have never been replaced as no-one makes aftermarket ones. Is it correct to assume that because the torsion bars are original and we have fitted better dampers all round that this will occur. (the OME kit is still in/on the truck)
Has anyone had this trouble on their 4wd(regardless of make)
Any help would be greatly appreciated.
greg

Collyn,
By double bounce I mean that when we go over bumps/ speed bumps etc the front end seems to want to continue to go up and down. It's like the damper is not doing it's job. When we had the Trek and Tow kit in, we used to pick up our daughter from school and had to go over speed bumps, when we did this it felt like the front end was going to
cave in under you. The wheels would drop back down to the road with a big thud, even going slow. The edelbrock dampers fitted with the TnT kit have a oil bypass system in them to allow the damper to return to the road quicker, which is fine, but they kept going up and down.
Now we have the OME kit in it is still there, though not as bad, but still, you feel it through the seats.When going over speed bumps now it is a lot better and you don't get that feeling that the front end is going to collapse.

Hi Greg,
I don't have a Terracan, and my only experience with "double bounce" was with a few cars, that
a) had faulty shockers...(in your case they have been replaced, but you would notice the "dead shocker"
b) a cracked spring on the rear of my Rangie.
My regular everyday vehicle is now a Rodeo, and it 'almost' exhibited pogo-ing effect, and lots of steering pull(even after an alignment!)
On it's only ever service at a Holden dealer, I asked if they could align and re-set the torsion bars (I know know how easy it is to do!!), and it raised the car by 50mm (:o and it felt much more steady.
either you got dud OME shockers (unlikely) or you need the tortion bars re-checked/replaced.
If you are up for an easy job, all you need, is some patience, a large socket(easier than a ring spanner), and a good small ruler something about 4-6 inch.
Wind up the tortion bars, the large nut will be obvious, and make sure the bump stop clearance on both fronts is the same (after a
test drive or severe bounce
test.....a couple of your heaviest freinds boncing the front end up and down!!! :))
Note: you can easily wind it up too much , so take care.

Hi arthurking83,
Thank you for the info.
First of all I will get it back to ARB to see if the correct dampers were put in, if all ok then I will change the rear springs back to original and see if that makes a difference, and if it doesn't then I will have a chat to my Hyundai dealer to see when they can have a look at it.
I've adjusted the torsion bars so that
the gap is correct and it made no difference at all, so I'm not to sure what is going on.
