Parts for your 2014 Lexus Is-Rack boots

2014 Lexus IS rack boots: purpose, servicing and when to replace

Based on Lexus/Toyota technical documentation for the 2014 IS (XE30)—including the Lexus Repair Manual on Toyota TIS and the Lexus Electronic Parts Catalogue (EPC)—this model uses a rack-and-pinion steering gear with bellows-style rack boots (also called steering rack boots or gaiters). Even though most 2014 IS variants run electric power steering (EPS), the rack boots are still present to protect the inner tie rods and the rack ends from dirt and moisture. These sources list the component as “Boot, Steering Gear,” confirming rack boots are fitted and serviceable on the 2014 Lexus IS.

On a 2014 Lexus IS, the rack boots are the flexible bellows on either end of the steering rack. Their main job is to seal out road grime, water and grit, while keeping the correct grease around the inner tie rod ball sockets. That protection prevents premature wear of the inner joints and the rack itself—especially important on Aussie and Kiwi roads where rain, dust and the odd gravel stretch are part of life.

Inspection is straightforward and should be part of routine servicing. With the front end safely raised, a tech checks each boot for cracks, splits, oil or grease weeping, and loose or missing clamps. On EPS models there’s no hydraulic fluid inside the rack, but a torn boot can still let in contaminants that chew through inner tie rods and seals. If a boot is damaged, replace it promptly to avoid a spendy rack repair.

Replacement typically involves removing the outer tie rod end and sliding the old boot off, then fitting a new boot with the correct bands. Key points a good workshop will follow:

• Use the correct boot and clamps for the XE30 rack, avoid generic cable ties.
• Don’t twist the boot—it must compress and extend freely through steering travel.
• Lightly grease the inner lip to seat it without nicks, keep any vent path clear.
• Reinstall the tie rod end to the recorded measurement, then set the wheel alignment to Lexus spec.
• Torque fasteners to the Repair Manual’s values and recheck for boot interference at full lock.

For owners, a quick glance at services—every 10,000–15,000 km or annually—is cheap insurance. If there’s a click over bumps, uneven tyre wear, or grease slung on the control arms, book an inspection. Genuine or quality aftermarket boots are both fine when correctly fitted, and replacing them early can save the steering rack from an early retirement.

Popular questions about 2014 Lexus IS rack boots

Do all 2014 Lexus IS models have rack boots?
Yes. Whether it’s IS 250, 300h or 350, the XE30 platform uses a rack-and-pinion steering gear that includes bellows-style rack boots. EPS doesn’t delete the boots—the boots still protect the inner tie rods and rack ends from grit and water.

How often should rack boots be checked on a 2014 IS?
Have them inspected at every routine service (about every 10,000–15,000 km). Boots live right near road spray, so small cracks can appear over time. Early detection avoids inner tie rod wear and keeps steering feel tight and precise.

Will a torn rack boot damage the steering rack?
If left torn, yes. Contamination gets in, grease gets out, and the inner joint can wear quickly. That can lead to free play, noises and ultimately rack damage. Replacing a boot and realigning is far cheaper than replacing a rack assembly.
