    My 2007 Prius has had some noise issues in the front end. After having the struts replaced (which was needed), I still had the same noise. The shop said the control arms were causing that and they are replacing them today. But as they are working on it they said the sway bar is also contributing to the noise and because the mounts are severely rusted and deteroriated, they recommend simply removing the sway bar. They are saying that it isn't really necessary for this small of a car. They assure me it won't have a negative effect on safety. Does it make sense to remove the sway bar and not replace it?

    And this is a real suspension shop doing this work talking about this like this I'm not sure that this is right In the old days my cars that did not have sway bars I'm sure had different springs and other things tuned differently I would imagine to make up for it I can't remember any of those cars it was so long ago but it doesn't sound right Just deleting this sway bar and doing nothing else try it I mean it would seem to me quick maneuvers like swerving in and out of traffic will become a lot more skittish but Prius drivers don't do a lot of that so maybe it's possible I wouldn't say it would become dangerous but may be quite a bit more noticeable that things are a little more lively sloppy if you will. I would think checking out and looking into some suspension sites that really spend a lot of time with this dealing with aftermarket parts deleting various parts I'm sure there are some I haven't looked in years I'll have to look over on Toyota mods tonight and see what the general consensus would be.

    I remember why this is not wise to be doing because it's going to make the car a lot wider and lean a lot more especially on the pavement I don't think you're going to appreciate it at all You can try it You will probably tell me it feels unsafe I do find it quite surprising that they're telling you that this would be okay It's kind of funny actually.

    It's going to lean over with every corner you make. Even with that small of a car, it'll handle like crap.

    I'm confused on the whole sway bar mounts thing. Is the frame rusted out where the sway bar mounts? Or is it the sway bar brackets, which wouldn't be that expensive (39.00 each)? Or is it the sway bar links (aftermarket $49 with bushings total)?

    In either case, I'd tell the mechanic he can drive without the swaybar in his car if he likes it so much.

    Unfortunately, if the sway bar actually needs replacing, it's a pretty big job. I don't believe the Gen 2 front sway bar can just be dropped and swapped. There are some interference issues that would add some labor costs.

    That's what he was getting at. He said it would involve lifting a lot of things out of the way, including the engine most likely. This is what he told me... "With as small as your car is, you shouldn't be able to notice any difference nor should the car behave any different." They have done work for me in the past and do good work. I may have to take it to the dealer to have it assessed better.

    In the big scheme of things, it's a Prius.....a little noise? eh....or...
    How many corners you take at full speed?
