Q: How to renew the anti-roll bar and bushes on Toyota Yaris?
A: To renew just the anti-roll bar drop links or bushes, much less additional dismantling is required compared to removing the bar itself. For Echo models, begin by raising the front of the car and supporting it on axle stands, then remove both front wheels and the engine lower covers. Next, remove the split pin on either side, unscrew and take off the tie-rod balljoint nuts, and detach the tie-rods from the swivel hubs using a balljoint separator tool if needed. For models with hydraulic power steering, unscrew the feed and return pipe unions, disconnect the pipes from the steering rack, and plug or tape over the open unions to prevent fluid loss or dirt entry. Unbolt the steering pipe support bracket from the subframe, allowing the steering pipes to be moved aside for access to the anti-roll bar. Unbolt the exhaust system for access, which may only require unbolting at the front and lowering it for sufficient access. Hold the drop link against rotation with a spanner, remove the upper and lower nuts, and disconnect both links from the lower arms, recovering the washers and rubbers while noting the order and orientation of all components. Remove the two bolts securing each clamp to the subframe, lift the clamp from the anti-roll bar, and remove the split rubber bushes. Carefully manoeuvre the anti-roll bar out between the subframe, suspension arms, exhaust system, and the underside of the car, taking care not to damage the disconnected power steering pipes. For Yaris models, the steering rack must be removed to access the stabiliser bar, although the link and anti-roll bar bushes can be renewed without removing the stabiliser bar. Refitting involves reversing the removal steps while ensuring all fixings are tightened to the specified torque, using a new split pin on the tie-rod end balljoint nuts, and tightening those nuts up to 60° past their torque value if necessary. Additionally, top-up and bleed the power steering system for models with hydraulic power steering, reattach the exhaust system, and check the front wheel alignment upon completion.
