You will never, ever have a problem with the sway bars. They are simply metal bars. Nothing to wear here. The sway bar drop links are the only item that fails and this is because the balljoit in each end wears and then gives enough play to rattle. Once this happens, regreasing will not recover it and a new pair should be fitted. Changing these has absolutely no effect on wheel alignment so there should be no concern about an alignment being done, even removing and installing a replacement sway bar will not affect alignment.

Uprating the roll bars greatly improves handling but this is a performance replacement rather than a necessary service item. There are sway bars both front and rear, and hence drop-links front and rear. Sport models already have an uprated rear bar, a good mod for a non-sport model.

The only other wear item is the rubber sway bar mounting bushes which deteriorate with age and can be replaced with better polyurethane bushes. These are normally good for at least 80000m but are cheap enough to replace and enjoy the more accurate location offered by the poly items.
