How much shimmy...?

Once you lift your rig and put tires on it, how much shimmy is to be expected when going slowly over bumps? At higher speeds, everything is cool...it's just at low speeds (10-20 mph) over bumpy terrain where I hear/feel the steering shimmy? Again, is some shimmy to be expected?

Depends. 2 jeeps done respond the same to the same lift. Mileage, wear on parts, even though there're good, tires etc.

The steering stabilizer should help with the small stuff. If the shimmy is more severe or gets progressively worse, you probably have something going on.

Everything is new... I'm just wondering how much to expect... I guess one measure would be how well it drives in "normal" conditions, which is fine in this case... I'm wondering if it's something like an a/c tube I'm hearing vibrate at times?

Steering feedback is normal. Shimmy is not. Do you have a tire with a flat spot? A loose bolt on the Track Bar?

Something is off. The axle does shift, but if the bolts are properly tightened and everything is aligned, you shouldn't be able to feel it shift.

What is your definition of steering feedback then? So I can gather whether this is it or not...

Does it vibrate when applying the brakes? If so, could be a warped rotor.

If it isn't a warped rotor, it might be a tire that is out of round. Try moving front tires to rear, one at a time, to see if you can eliminate the vibration. In addition, check the torque of you lug nuts.

Not during braking... Did a rotation...psi is 30...it's aligned...but this has always gone on...just wanna know that it's normal for a solid axle truck... I can't believe there's a Jeep owner out there who hasn't felt the steering wheel shake from time to time....

Steering feedback is just what it sounds like. It's a pressure in the steering wheel from the tire moving over an obstacle and feeding back through the steering components. But it should be barely noticeable at slow speeds. Any kind of clunk or thump or feeling of metal on metal contact goes beyond feedback to loose components.

An out of round tire can make the whole Jeep wobble from side to side at speeds of 1-2 mph.


KJ had asked you a question up above. Do you hear the shimmy or just feel it?

Mike

I acualy think I know what ur talking about is it when you are at a red light and then the steering wheel shakes and pretty much feels like a motor mount is shot but it isn't a motor mount because it happens randomly and it's not every time u stop because I have had that happen to me before

Need to drive my jeep rofl.

Like a roller coaster ride. Jerky but its the whole jeep, not so much the steering. I have no idea what's causing it.

Def not cool with it

Hard to drive at times. I need to have it aligned. Get numbers and see if anything is bent.

Subscribed interested in what it may be. I have something similar don't gear it but can feel something thru the steering wheel and pedals occasionally.

These pedals shake a lot...have heard numerous complaints on that.

Not so much a shake as almost a clunking type of feel. Going to climb under it tomorrow to check to make sure everything is tight but it should be just got it back after new tie rod drag link and alignment and he couldn't find anything else loose or bad

There is a section of highway I drive almost everyday where I will get a shimmy in the steering wheel. There is a spot with a drop off of several inches between sections of pavement. Steering wheel will shimmy back and forth a few degrees left and right for a few seconds. Rest of the time I get zero feedback.

Do you detect the shimmy at every bump or just certain ones?

So except for certain bumps, your Jeep has zero shimmy?

Come on guys it is simply a case of bump steer which is more noticeable when going slow because the slower the tires turn the less they act like a gyro. That's not a perfect analogy but it s the best I can come up with this late in the day.

This is the one thing that a steering stabilize is good for.

Come on guy I never said it wasn't bump steer. Simply confirming The_Chief's Jeep did the same as mine.

But no one ever told the OP what it was. Unless I completely missed it.

It's all good, man... I'm not freaking out... It's my 1st live axle vehicle, so I'm not sure what to expect or look for... To be quite honest, I love the 'torquey' feel of the Jeep--it actually feels like a truck should feel to me...
