Stock Sway Bar Links on Lifted Jeep?

I just lifted my Jeep with a 2.5" lift but got closer to 3". I am currently using the stock sway bar links. I am currently troubleshooting some vibe / wobble / shimmy issues but wonder if the sway bar links have any part in the issues.

I am not really looking for specific diagnostic of my current situation but I am trying to learn how the sway bar links play a part in the entire suspension setup. I eventually want to get some adjustable links from JKS, when the budget allows.

My question is this...what will I notice in drive and response if I use the stock links for a while? Does this impact body roll? What does it impact? Thank again for all the help I have received on this forum!

When is the wobble occuring. When you start off? If so did you do a transfer case drop?

If it is between 40-50 mph, it's likely a tire ballance issue

No the swaybar links will not cause a wobble. Sway bars are for body roll

Yes, the wobble does happen between 40mph-50mph. I was thinking tire issue as well. I am going to rotate the tires from front to back and see if that helps. If so, I'll go and get them all balanced.

As far as sway bars, I was going trough a check list and started thinking about body roll. I am not real sure what body roll is, bur I have an idea. When turning out of my driveway and turning at the stop sign, it just seems that the jeep is a little "bouncy" or "swaying" a little. If that is what body roll is, will adjustable sway bar links help with this?

That is what body roll is. New swaybar links can help some with that, but the sway that you are experiencing(at a 90 degree turn) is from the lift that you installed. when you lift it, you take your center of gravity higher which results in more body roll. once you have a lifted jeep, you cant drive it like a car anymore or you will be laying on your side wondering WTF just happened. As mentioned above, you wont get a fix on the wobble from new sway bar bushings. try getting the jeep aligned at a quality alignment shop that has experience with a lifted 4wd. that will cure a big part of the wobble, and the tires play a big part in it as well.

Stock sway bar links just plain suck. Mine broke as soon as I took it off road with just a 2" budget boost. Better to upgrade with a quality set of disconnect even if you never plan on disconnecting!

Many factors can cause that wobble. Could be one, or a combination of issues. Best to get on it now before it gets worse and ruins parts.

After you are sure your tires are properly balanced have someone sit in the Jeep (engine off) and turn wheel back and forth looking for any movement in bushings, trackbar, steering, control arms, etc. etc. I had an adjustable front track bar that would loosten up at the frame mount and start a wobble at 40 mph +.

stock links suck...the ends suck, the ball stud sucks...you need to replace them with a lifted vehicle. get the JKS when you can, but don't be surprised if the ball stud busts open pretty soon.

however, the stock sway bar links have nothing to do with your tire wobble. address the reduced caster, rebalance the tires (road force), and set toe-in alignment.

Since I drive on road more than off-road, and since most of my driving is a little "spirited" as my GF says. When I "break" a sway bar link, on my TJ, it is very obvious to me. It has been the driver's side 2x and passenger side once. It is "VERY" unnerving to me, for it to feel as if the Jeep is going to lift up and twist over on its side when accelerating, and making a right hand turn really adds to the feeling. I have been told that it is not possible, but I have seen videos of this happening. IDK if the videos were with or without the sway bar link, but I know it makes me "feel" safer and more in control. I also understand the reasoning for disco's on the trail, and will "eventually" get some.

IMO the sway bar link is totally NOT a part of your wobble issue, I have experienced wobble 2x, as you- between 40-50mph. Balance and rotation has always solved my problem, but I realize it is not that way for everyone. GOOD LUCK!!
