Got a new rear sway bar on order for my Sonata, am I going to need to have this thing aligned afterwards? And do you think I can change these out without jacking the car up? I can back it up on ramps but I currently donít have a jack.

No need for an alignment and ramps should be fine. Your end links may give you trouble in getting them off, be prepared to buy new links.
I assume you are going stiffer? What handling change are you going after?

Good suspension pictures here.

No alignment needed, use the jack in the trunk and slide the tires under the car for safety. Might be able to lower the car's pinch weld onto a ramp to use as a jack stand.

You can change it without jacking it up.

Progress customer service sucks. Their sway bar bushings are [censored], one of the bushings was shot less than 1 month / 2k miles. They give me [censored] excuses not to send a replacement. They claimed/guessed that I had an aftermarket exhaust (which they were wrong), and they blamed me for not using a "heat shield" for a friggin rear sway bar. I sent my OE exhaust pics, eventually they admit it's their fault and sent me the replacement. They tried so hard not to accept their fault for selling a defective bushing which costs less than $10. I can't imagine if it was an expensive part, I would have been on my own.



I'd get another aftermarket sway bar, or get some energy suspension universal bushings and keep them as a spare set.

Likewise. I have only met a couple of qualified folks who tune suspensions at the track, never seen anyone do much in a driveway except change their handling. For better or worse?

Pretty hard to beat the factory at that game for overall safe handling without risks.

And I also note that my sig car has elaborate little shields over the sway bar bushings. If any are within a few inches of exhaust components they may be a good idea...

A larger sway bar will reduce body roll during turning. I have changed a few cars rear bars for improved handling, reduced understeer. Poly bushings are available from energy suspensions for a "tighter" feel

Thanks, I'm well aware of what a stiffer rear A/S bar does. Still not sure the need of a new bar on a '17 Hyundai in day to day driving. Is the OP going to track days? A Sonata isn't really know as a car for spirited driving. Just curious what the OP's needs are.

I would sure start on the soft setting atleast. Seems 17mm is stock and jumping to 22mm seems a bit excessive with no other changes, but do some reading on a sonata forum and see what other guys have found that works.
Adding a rear sway bar will reduce understeer, but not do all that much for reducing body roll overall(a front bar will help that), but if you just want to have more fun autocrossing a fwd car, a rear sway is a good way to get the option to rotate the car more. Just respect that the car is not idiot proof anymore and jerky steering inputs at high speeds may be more exciting than you want!

Goal is merely to reduce the body roll to any degree possible, even if marginal. New rear sway was really the only way without changing out the springs. Definitely may add a strut tower brace at some point or a lower body brace. If I were to change the front sway Iíd probably just order the factory one off of the sport trim. I got the Progress because I like itís ability to be adjusted, but for sure will start on the soft setting. Thatíll probably be enough for what Iím wanting.

Glad to know that I can change this out without a jack. Besides, if I end up not liking it I can always put the OEM one back. This isnít a huge permanent difficult change.

Yea itís for sure not a spirited driving car but itís the car I bought and I want it to handle a little better is all.

Now you guys have me thinking I shouldíve just ordered the Sport trim front sway and skipped the rear sway. Well too late now, it already shipped and I donít think I wanna pay return shipping on it.

Tried to find the specs on the Sport trim sway bar and I can't find it anywhere. So I'm not sure they are in fact larger, but they'd almost certainly have to be with being a Sport model, right? A front sway from the Sport would be $100 vs the $170 I spent on the rear sway. Hmmmmm.....

Front sways can require a few things to be removed to change out. Can you find out the spring rates for the sport trim struts? IF they are stiffer than yours, maybe find some front struts at the wreckers to swap in?
Anyways, if you've ordered the rear sway, try it out and if it makes the back end too loose, put the stock one back in and sell the sway bar for a cheap lesson learned.

Just remember to have the wheels the same height off the ground if you're jacking up the car. Don't just jack up one side or you'll never get the sway bar installed.

Do not skip rear sway bar.

I used Progress 22 mm rear sway bar in my Civic SI, and OE sway bar is 17 mm. So I guess it's very similar with your situation. Let me tell you, it makes a night and day difference.

You need to get rear sway bar first if it's a FWD, rear end must be stiffer than the front. It will reduce understeering, as the other guys mentioned. Don't worry, rear sway bar will reduce body roll as well.

You wouldn't want to reduce roll in the front with aftermarket sway bar. Front wheels need to stay on ground when cornering, especially if you don't have a limited slip. So that's why aftermarket FSB is not the best option if you are looking for best grip. Even some FWD track cars have thinner / no front sway bar to get better traction. You should get a thicker FSB (with thicker RSB, of course) on FWD car only if you do autocrossing, as it would increase initial turn in feedback and steering response.

If you buy FSB and skip the rear, you feel like there is less body roll, but you will have less grip on the front and will have to deal with more understeering.

Check if you have any OE alternatives for rear. I currently have 2015+ Honda Civic SI 20 mm rear sway bar on my Acura (OE RSB diameter is 11 mm). The reason why I went with OEM is $$$$$. I bought it for $50 at the dealer, whereas the Progress is 200$+ Canadian.
