    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?

    I think you could change the sway bar like you do the rack in this model I haven't tried it I have to go out and look at the car that's sitting on block that's getting it snatched up pretty soon and off to salvage but it's all sitting up so I can cleanly look under there and take a look I see how to get the rack out I'm wondering if this sway bar can be dealt with and similar manner which won't make it horrible on the labor a little more but if you did it in your driveway well you'd be saving all that It looks doable and I guess if you're going to do that get you a Corolla matrix or whatever bar and it's mounts and bushings and bring it all You could go swipe it off of another car at the junkyard well hopefully in better shape than you have where you are.

    It's a pretty sorry excuse to say you have to move too many things to replace a sway bar. It's just a couple boltson the catalytic converter and some front end parts. where they connect to the suspension near the wheels. Any mechanic with basic experience could do this in a couple hours. Just fix it the right way and no more excuses.

    Nothing on a Michigan, Indiana or Ohio car is ever easy.....it's always the worst possible fastener that breaks also, turning a 2 hour job into a 6 hour job.
    Heck, hit the sway bar with a hammer, it may just fall of the car.

    Yeah in those places usually these kinds of jobs may take the car off the road to be honest about it it can be that bad so it just depends where you are in the mess basically.

    Read the original post again. There was mention of the sway bar mounts being deteriorated. Having the sway bar itself fail is extremely rare.

    Depending on what exactly is "rusted out", the OP may be looking at having to replace the front suspension cradle, or maybe it's just the bushing mounting "clamps" (but the hardware could be seized or eroded).

    Not enough information to make judgement. Lots can go bad up in the salt belt.

    That said, no way would I "delete" the front sway bar.

    That makes sense for DIY folks... But back when I worked as a mechanic the boss would never accept "I can't get it off" as the answer to a problem. Probably the most important lesson I learned in all my jobs related to working on vehicles ---> You have no choice but to figure out how to remove the old part and put in the new part. There's no other option! This often led to the shop's most challenging moments, where everyone who worked there got involved.
