jeep bouncing on highway

Ok will I hit a bump on highway and my front end started boucing. Pulled over and checked nothing loose. Drove on hit another bump and samething. It's like running over the rumble strips on the side of Highway. I don't know what lift the 1st owner did to it but I know it's higher than normal I'm guessing a 3 inch. Help please I just got this and don't know what to do.

Have you checked to see how tight your track bar is torqued??? I have to retorque mine almost daily. Hope this helps.

Hi Momma!

For starters, welcome and nice Jeep!

First question I would have is define "bouncing?" Is it like the front end is just bouncing up and down like an old Cadillac with air ride? Or is it more of a shaking?

This is what DW looks like from inside:


If that looks familiar, follow the link provided by Old Dogger and I think you will be able to hunt down the source.

If its more of a bouncing, then it might be worth checking your front shocks.

Good luck and let us know how it turns out!

Bouncing usually implies a vertical movement of the whole Jeep, where as DW is a violent side-to-side movement of the wheels. Vertical movement is controlled (dampened) by the shocks. When they wear out the Jeep will continue to move up and down after it hits a bump.

They are easy to test. Stand in front of your Jeep and push down as far as you can on the from bumper then let it go. Watch the bumper motion. It should go up once then down and stop. If it moves more than that the shocks probably need replacing.

Now if it has a lift on it how do I fine out what shocks to use since the factory style won't work.

The shocks are Procomp. Is the MX6 adjustable ? Might want to look into that.

Assuming the coils are very saggy Procomps as well. There's little spacing at all which I don't think is normal.

Verdict
Shocks, decent when new
Coils, sagging (maybe)

That coil does not look right at all.

Yes, as Daggo said the coils just don't look right. The are almost fully compressed at ride height so they must be worn out. Not too surprising for Pro Comp.

Momma Gator t sounds like you aren't too thrilled about the lift kit. If this is the case, the solution could be relatively cheap minus labor. Buy the stock take-off coils and shocks from Rubi X owner and completely remove the existing lift. If you do like the lift then you will need purchase a quality lift kit.

The coil cannot compress, no absorption.

Or grab some stock coils and install a simple budget boost. Pull the shocks and test them out. They should be gas charged and return when compressed. The MX6 is a Decent shock. No need to buy new if they work.

If your Jeep is doing the same as the Jeep in the video it is not shocks. You have something loose in the steering components like ball joints and tie rod ends. You need to go to a reputable 4x4 shop and have them check for death wobble. I agree the springs look compressed but it they were bottoming out it would be a solid thump on harder dips and bumps. You may well be looking for a solution for the problem that caused the previous owner git rid of the Jeep. Don't be disheartened though, it can be fixed. This is a common problem for solid axle vehicles that showes up usually due to multiple worn components. Your front tires are doing the same thing you see happening to the front wheels on a shopping cart when they shake back and forth.

WOW, them springs are almost totally collapsed, and bottomed out, (wraps almost touching)!
They are the first component that needs to be changed out! Next test shocks, and then, go from there.....

There are tons of places to buy springs on the Internet. As there are tons of different springs that you can buy. There is a few stickies at top of this sections about lifts. Read through that and see if it helps. Depending on how much you want to spend maybe just start fresh with a new lift altogether. No telling what your Jeep has on it now and if it was lifted properly. More people will chime in on where to buy or look, but like anything you get what you pay for. Suspension and tires are certainly 2 places not to go cheap on, as they can make driving your Jeep miserable. Probably already figured that out though sounds like. Good luck and keep reading and researching.

Ok I checked the stabilizer shock. My question is it like a regular shock if you remove one end should it slide out on its own like a shock.

Stock no
A gas charged aftermarket SS will.

Take it off and see how easy it is to move by hand the hard it is the better.

Is it stock ?
A bad SS, you won't feel any resistance when compressing it. If there's no oil around the seals leaking or damage .. It's prob fine.
A bad SS won't cause your problem any ways. Do this ... Remove it totally and drive. See if your problems persist. (You will feel a little more feedback in the steering wheel)

As just noted in the other thread you posted in. His track bar was the culprit. A loose TB bolt, worn hole, worn bushing, cracked weld joint-all these can cause DW issues.

Ok so got the 9/16 bolts for the stabilizer bar replaced and took on interstate and still have the death wobble. Checked the stabilizer shock and it's good. Any other ideas. Please

Check the bolts on the track bar. Those are the ones that really need to be replaced.

Possibly your ball joints. Your husband can check the ball joints. If they move back and forth effortlessly, they need to be replaced. I have Synergy ball joints.
