This is hard to describe but I will try. What would cause a "rough" ride that is not wheels and tires? Long story short, part of it was bad wheels, got new wheels and tires but something still doesn't seem quite right. I get A very slight vibration in steering wheel at high speeds and at low low speeds (rush hour traffic speeds) I feel like my jeep has a limp, sort of rocking side to side. What gives? I have done everything from an alignment to new wheels and tires so what's left???

 

Are there any mod's to your Jeep? Your profile doesn't say there are. Also, how many miles on it? 2009 Jeep, assuming you drive it regularly, it could be any of a variety of worn parts. I'd check (or have a mechanic check) the tie rod and drag link ends and the ball joints. If you're still running original ball joints, that might be your problem. If bad, recommend replace with Synergy instead of the weak OEM. However, the Synergy's will require periodic lubing or they will wear out pretty fast. Also, what tire pressure are you running? Tire shops often fill way too high. If you haven't checked, recommend you do so. And if running oversized tires, you should be running less tire pressure than indicated on the door placard. Do a chalk test to get best results.

 

No mods done. I've got close to 100k on it. Unfortunately I would have to have someone check all that stuff (joints, tie rod) not to savvy with that yet.

I am at 35 psi which I suppose I could lower but I don't think that is the problem. I've done that before and it still felt like the jeep had an uneven ride at slow speeds and a not so great ride at higher speed. Almost like I could hear the vibration if that makes sense. Oh and I just thought of another thing that may help describe what I'm trying to say. I have a slight squeak in the brakes and when slowing down it's not a constant squeak. As I slow it squeaks with the rocking motion of the jeep if that makes sense. Instead of a contact screech it's screech.

 

Maybe you have a break caliper seazed on a rotor. Happened to me.

 

That would be a shame, I just had brakes redone earlier this year. But I can recall experiencing the problem after brake work was done last year. The timing makes sense to me. Hmmm I just figured something like that would be more noticeable. What was your experience like?

 

Death wobble perhaps. My JKU 2008 started around the same time. Stock mainly but had replaced the tires with slightly larger than stock Wrangler silent armor. Not really related but giving you the full picture. The problem is effected my temperature and was improved when I had the tires balanced and rotated. Check the link and see if you have the same basic feeling.

My steering stabilizer is most likely the cause and I am planning on replacing it ASAP.

 

You may have a warped rotor. This can happen if the wheel lug nuts are torqued too high, which can happen if a shop uses an impact wrench to tighten the nuts and runs them down way beyond the specified value (about 100 ft-lbs). If you went to a typical quicky brake shop they may not have checked your brake rotors for runout, or they may have been the ones who over-tightened the lug nuts. Suggest that you have a good mechanic check each rotor's lateral runout, especially the front since you feel it in the steering wheel.

 

Death wobble is a very violent shaking of the front end. When it happens, the only way to stop it is to bring the vehicle to a much, much slower speed. Say, you're driving along the Interstate at 65 when it starts, and you have to slow to 30-35 to make it stop, the shaking remaining just as violent until it finally does stop. This can obviously be very dangerous. Once a vehicle does experience death wobble, more and more damage occurs to the components of the steering and suspension. With each incident, yet more parts will be damaged and need to be repaired. Unless caught very, very early on, usually it will take multiple parts/repairs to make it go away. It doesn't sound anything like what OP is experiencing (fortunately for him).
