Parts for your 1999 Toyota Crown-Sway bars & links

1999 Toyota Crown Sway Bars & Links

Referencing technical sources, the 1999 Toyota Crown (S170 series, e.g., JZS17#) is fitted with both front and rear stabiliser (sway) bars and separate link assemblies. Toyota’s Electronic Parts Catalogue (EPC) for the S170 Crown lists stabiliser bars, D-bushes, and link assemblies at each end, and Toyota repair manual procedures for the model detail inspection and replacement. Common aftermarket EPCs and workshop data providers also show the same components and layouts. So, sway-bars-&-links are absolutely relevant to the 1999 Toyota Crown.

On this Crown, the sway (stabiliser) bar ties the left and right suspension together to reduce body roll in corners. The links connect the bar to the control arms or struts, and the D-bushes clamp the bar to the subframe. The upshot is flatter cornering, better tyre contact, and more predictable handling. When everything’s healthy, the Crown feels composed over uneven roads and quicker lane changes feel stable rather than floaty.

As part of servicing your 1999-toyota-crown sway-bars-&-links, a quick underbody check goes a long way. Look for cracked or perished D-bushes, torn link boots, rust weeping from ball-joints, or loose hardware. Worn links or bushes usually announce themselves with a dull knock over speed bumps, extra body roll in roundabouts, and the odd squeak on rough chipseal. Because the links are compact sealed joints, there’s no greasing—when they’re loose, replace them.

It’s smart practice to replace sway bar links in pairs on the same axle to keep handling balanced. Bushes can be swapped side-by-side as well. When installing, snug everything up with the vehicle at ride height so the bushes aren’t preloaded. Most Crown sway bar work won’t affect alignment, but if other suspension arms are disturbed, a check is wise.

Service intervals are condition-based: inspect every 10,000–15,000 km or at each service, especially if the Crown sees rough roads or carries loads. Rubber bushes deliver OE ride comfort, polyurethane options sharpen response but may add a hint of noise. Aftermarket links with metal ball-joints are fine so long as they match OE length and stud taper.

• Common symptoms: clunks over bumps, excess body roll, vague turn-in, visible play in links, split rubber.
• Quick tips: replace in pairs, torque at ride height, recheck fasteners after a few hundred kilometres.

Does the 1999 Toyota Crown have front and rear sway bars?

Yes. The S170-series Crown runs stabiliser bars front and rear with separate links and D-bushes. They’re integral to keeping the big sedan flat and settled through corners.

How often should sway bar links and bushes be replaced?

There’s no fixed kilometre count—inspect each service. Many last well past 100,000 km, but high-mileage cars or those driven on rough roads may need links and bushes sooner when knocks, roll, or visible wear show up.

Can worn sway bar links cause a WOF/RWC failure?

They can. Excess play, damaged ball-joints, or insecure mounting is usually a fail item because it affects handling safety. Fresh links and bushes generally restore compliance quickly.
