Parts for your 1999 Toyota Hiace-Rack boots

1999 Toyota Hiace rack-boots — are they used on this van?

Short answer: a typical 1999 Toyota Hiace (H100 series sold in Australia and New Zealand) does not use rack-boots. That’s because these Hiace models run a recirculating-ball steering gearbox with a pitman arm, relay rod and idler arm, not a rack-and-pinion assembly. Rack-boots (also called rack bellows or gaiters) are specific to rack-and-pinion systems, so they’re not a service item on this van.

This isn’t just workshop folklore. The Toyota Hiace H100 Repair Manual (steering section), the Toyota Electronic Parts Catalog for H100 chassis (RZH/LH/KZH, circa 1995–2004), and the parts illustrations all show a steering gearbox and linkage—no rack, no bellows. Toyota’s launch material for the next-generation H200 (from 2004) even highlights the switch to rack-and-pinion steering, which underlines that earlier H100 models like the 1999 did not use it.

Why no rack-boots here? Rack boots protect the inner ends of a rack-and-pinion unit and keep grease in while keeping grit and water out. Because the H100 Hiace uses a steering box and external linkages, there is no exposed rack tube to cover. Instead, the system relies on dust boots at the ball joints and tie-rod ends, and on seals within the steering gearbox and idler arm.

What should owners and mechanics check instead of rack-boots?

• Steering gearbox: input/output shaft seals for leaks, free play, and correct pre-load.
• Pitman arm, relay rod and idler arm: wear in bushes and joints, any looseness or knock.
• Inner/outer tie-rod ends: torn dust boots, grease loss, play.
• Power steering fluid: condition and level, seepage at hoses and pump.
• Wheel alignment and tyres: uneven wear that hints at steering or linkage wear.

Worth noting: a handful of region-specific or modified vehicles can differ. If there’s any doubt, confirm by VIN in the Toyota EPC or by a quick visual—if there’s a steering box with a pitman arm and idler, it’s not a rack-and-pinion, so there won’t be rack-boots. If someone’s asked for “rack boots” on a 1999 Hiace, they may actually mean the dust boots on a tie-rod end or idler arm.

Popular questions

Do 1999 Toyota Hiace vans have rack boots?
Most AU/NZ 1999 Hiace H100 vans don’t. They use a steering gearbox with linkages, so there’s no rack-and-pinion and no rack bellows to replace. Focus inspections on the steering box, idler arm, and tie-rod end dust boots instead.

My mechanic says the rack boot is torn on my 1999 Hiace—what gives?
It’s likely a terminology mix-up. On these vans, the usual “boots” are the small dust boots on tie-rod ends or the idler arm. Ask the shop to point out the part on the vehicle, if it’s a Hiace H100 steering box setup, there isn’t a rack boot to tear.

How often should the steering on a 1999 Hiace be checked?
Have a look every service (around 10,000–15,000 km). Check for fluid leaks, torn dust boots, play in the idler arm and tie-rod ends, and uneven tyre wear. If the steering feels vague or the van wanders, book an alignment and a steering linkage inspection.
