I'm getting vibrations at 60-75mph that come and go. I am going to rotate the tires again soon and re-check the pressure and see if this helps. I have a budget boost and 35s on the stock rims which are roadforce balanced. Could the vibrations be from my rim width being too narrow? I was thinking if I got some 10" wide rims it might get rid of this issue but they are not cheap so I want to be sure. This is my daily driver so if I could smooth out the drive that would be awsome. Would this also possibly solve or help the flighty steering feeling at highway speeds? Or could the vibration be from something totally different like my driveshafts? I know it's a lot of questions but any input would be appreciateed. Thanks!

 

anybody got some input?

 

Your vibration can be caused by many things but look at your tires for proper balancing first. Rim size will not make a difference. Another thing to look at is have you changed or added anything to your jeep lately? Sometimes a out of balance drive shaft can cause a vibration. You really need to do some process of elimination.

Your flighty steering is caused by the change in caster when you lifted your jeep. There are a few ways to correct this. Any one of these will help.

1. buy adjustable upper control arms
2. Install the cam adjustment bolts into the lower control arms
3. Look into a adjustable front track bar to recenter your front axle

All of these things will achieve the one thing you changed which is your front end alignment.

Do a search on flighty steering and you will see alot of info.

 

I always look at tires first when I have a vibration. Check pressure and wear. If they look ok then rebalance. Mud terrain tires in general chop and vibrate quicker the less agressive tires. How often do you rotate?

And as DCMP001 said, the flighty steering is most likely from an un centered alxe and the caster being too low. Id try an adj trackbar first since it is cheaper and easier to install. Although watch which one you get because some are too long for lifts under 3". I had flighty steering with my BB, but it disappeared after I added the adj arms and trackbar. I did both at once, so Im not sure what made the bigger difference.

 

x2, also slight toe-out will cause the vehicle to try to follow one front wheel or the other causing a really ''flighty'' feeling.... check for dried mud on the back of a wheel.

 

I rotate my tires every 3000-5000 miles. I haven't changed the driveshafts and I checked the tire pressure yesterday and the wear seems to be fine. I guess I'll get them re-balanced and see if this helps. Is there a lift that is upgradable to a long arm? I know i read this somewhere a long time ago.

 

I can almost guarantee that your tires need to be rebalanced. Larger off-road tires are hard to balance in the first place and it's not uncommon for them to need multiple tries to get them on right. Also, it's not uncommon to throw a weight especially if you go off-roading, this will cause them to get out of balance as well and being that you feel the vibes most at higher speeds, this is most likely your problem.

 

Actually, a loose steering stabilier will not cause anything but it can hide or mask problems that you might have with your suspension/steering. FWIW, I have over 31,000 miles on my stock stabilizer, most of which has been run on 3" of lift and 35" tires and I'm still using it now with my 37's. No leaks, no problems.

 

yeah, as I mentioned, a steering stabilizer can hide or mask a problem that you might have with your suspension or steering. Re-tightening your stabilizer simply made it work better again and now it is probably hiding whatever was really causing your flutter. Obviously, if you lost a weight on the trail, this will cause your tires to be off balance but if you were playing in the mud, the mud itself can pack in on your wheels and this can change the balance of them enough to cause issues as well. Either way, your steering stabilizer will not have been the cause of your flutter.

 

This may sound like I am being a jerk, and regardless of what my wife says I am not.......I don't understand the purpose of a stabilizer if it just covers things up? Why have one at all?
