2002 Toyota ist Rack Boots — What They Do and When to Replace Them
According to Toyota’s technical literature for the NCP60/NCP61 chassis (2002 Toyota ist), including the steering section of the factory Repair Manual and the Toyota Electronic Parts Catalogue for the IST/Scion xA platform, this model uses a rack-and-pinion steering gear with bellows-type rack boots fitted on both ends of the steering rack. These components are identified as “Boot, Steering Gear” in the EPC and shown in the exploded steering diagrams in the Repair Manual, confirming rack boots are absolutely relevant to the 2002 Toyota ist.
On this little Toyota, the rack boots are the flexible rubber bellows that seal the inner tie-rod joints and the exposed ends of the rack bar. Their job is simple but vital: keep grit, water, and road spray out, while holding the correct lubrication in. Whether the ist is running electric column-assist or hydraulic assist, the rack still relies on healthy boots to prevent wear on the rack bar and inner tie rods. Split boots let contamination in, which can quickly chew out the inner joints and, in some cases, track moisture into the rack housing.
As part of routine servicing, a visual inspection every 10,000–15,000 km is smart practice. Look for cracking, tears, perishing, oil or grease sling, or loose/missing clamps. If a boot is compromised, replace it promptly—waiting tends to turn a cheap boot job into an inner tie-rod or rack replacement.
- Common signs it’s time: visible splits, damp/greasy residue around the boot, a click or knock over bumps, or uneven, gritty steering feel.
- Best-practice replacement: do both sides if one has failed, fit new clamps, and book a wheel alignment afterwards.
- Centre the steering rack and mark tie-rod positions to preserve toe as much as practical.
- Remove the outer tie rod, slide off the old boot, clean the area, and check the inner joint for play.
- Install the new boot without twisting it, seat it fully on the rack and tie-rod side, and secure with quality clamps (avoid flimsy cable ties).
- Refit the outer tie rod, set the lock nut, and have a proper alignment done to protect tyres and handling.
Quality boot material (neoprene or TPE) copes better with Aussie and Kiwi conditions—heat, UV, rain, and the odd gravel road. A quick look at every service keeps the steering tight and the rack happy for the long haul.
Popular questions about 2002 Toyota ist rack boots
Do all 2002 Toyota ist models have rack boots?
Yes. Across the NCP60/NCP61 lineup, the steering gear uses bellows-style rack boots on both sides. Even models with electric power steering assistance still rely on these boots to protect the rack ends and inner tie rods.
How often should rack boots be inspected?
They’re worth a look at every service or at least every 10,000–15,000 km. If the ist sees rough roads or a lot of wet weather, check more often. Early detection of cracking or loose clamps saves the rack and inner joints.
Is it safe to drive with a torn rack boot?
Short trips might be possible, but it’s not ideal. A split boot lets in grit and water, accelerating wear that can lead to inner tie-rod play and costly rack damage. Plan a replacement promptly and get a wheel alignment afterwards.
