Bounce in the front end

06 H3 · Nov 3, 2014

I think the rancho kit helped because it gets rid of the angle on the control arms. It flattens them out. Same thing with jeeps. steeper control arms usually equates to worse hill climbing.

Spring over I am not really sure if it made a difference. I use the same springs. I will say disconnecting the sway bars make a difference IMO. It allows the suspension to work vs limiting it. I wish I had a video of the rancho/spring over climbing the steep hill at Last chance vs. a T bar crank one. There are many variables though.

Lastly I think the SAS will make the biggest difference. I dont have real world exp. yet to back it up but just on this one hill I was spinning vs. bouncing but again I was in mud. Either way I will get back to you on that.

I plan on disconnecting the rear sway bar next run but I've been told disconnecting the front doesn't make a difference when it's IFS. I do need to take a look at my abs wires before I disconnect the sway bar though. I would like to do a rancho kit but they are so expensive it's crazy.

Disconnecting the front and rear will make a huge difference.

Disconnecting the front makes a bigger difference then the rear IMO

The bounce is enhanced by a t-bar crank. I've noticed that stock (non-leveled) H3s don't have near the nose bounce as those that are running 23.5". I think when you crank the t-bars, the front suspension wants to un-load quicker and earlier than if you leave it around 22". Put the truck on a steep angle and the problem gets amplified further...it unloads even quicker and even earlier than it does on level ground. Prolly why the Rancho seems to have less bounce too. The front suspension operates closer to the middle of its range.

Ha ha...someone has apparently already solved this problem.

I don't think it is any one thing. I would guess a combination of the vehicle weight balance, t-bar setup, and rear suspension. I know I have never had my H2 do it at all, and it has basically the same suspension in the front, just scaled up. The rear, though, is completely different.

LS12FAST4U · Nov 4, 2014

Apparently I need to make some.quick disconnects for the front and rear. Do I need to worry about brake lines when doing that or just ABS wires?

LS12FAST4U · Nov 4, 2014

Do the alphas have this problem?

that is true, with a 4link you can built it with a certain amount of anti squat. Causing the rear end to squat or raise under acceleration. Causing it to raise will bring the rear end up and help with weight falling back to the rear.

I wonder what would happen if one copied the H2 rear link suspension on a H3. That would be a fun project.

I would but the leaf springs work so damn well in spring over form! I guess for tuneability a link suspension wins but these springs will flex to hell and back.

thats a 37in tire under the frame rail...lol

LS12FAST4U · Nov 5, 2014

That's what I need lol

Update I went to a local trail with steep climbs this thing climbs like a damn billy goat. Where I used to hop and bounce it is now planted. It almost crawls itself

Also thinking the h2 may not have this issue simply because of the wheelbase. Same with a 3T. Same exact setup just a longer wheelbase. They don't have this problem. Our wheelbase is long compared to jeeps and we struggle more then them.

To much money for me to do an axle swap up front.

Any fix to it?

Get a Bumper Monkey.

It is a combination of things. Like others have said, the sort springs, short wheelbase, heavy rear door with a heavy tire cantilevered off the back. T-bar crank will make it worse because it increases the weight transfer to the rear on the incline and the gap between the progressive dampener and the frame allows the t-bars to get moving which just makes it worse. Once it starts bouncing you just have to get out of it and let it settle down.

Would only getting the alpha t bars fix this issue?

06 H3 · Nov 7, 2014

its hard to say, I think there are only things that can aid this issue. I threw a winch on the front and alpha t bars before I did the SAS and that helped. I also learned how to drive and combat the bouncing issue. It takes practice. If I start bouncing I normally would back up and choose a new line or get some CONTROLLED momentum and use my left foot on the brake to help control the throttle.

LS12FAST4U · Nov 7, 2014

I'm definitely learning to use the brake and throttle to aid each other. I also know what you mean about backing up and trying a new line. I guess I'm more disappointed with then anything. I thought it would be a step up when I switched to the h3 and granted I have not been stuck or anything yet but I have been far from impressed.

What did u come from?

I wonder if xterras do the same thing they are spring under rear torsion bar front. Just like an h3

A 4runner on my offroad forum was complaining about the same issue, and my friends xterra did the same.

My old 06 before modding the front end did this some.

My Alpha as set up does not do this very much. It depends a lot on your right foot!
Sway bar link extensions and longer shocks and tie rods that articulate to 30 degrees instead of OEM 23 help.

Our last outing to Superlift when I was leading even on the rough steep climbs as long as I did not try to force it with speed it gave the suspension time to recover and stay on the ground.
Firm shocks come into play more if you do add speed to help keep the tires in contact with the ground.

Others I watched did hop a lot and got into awkward positions as they bounced off the better line.
