Parts for your 2004 Toyota Hiace-Rack boots

2004 Toyota HiAce rack boots — are they actually used?

Based on technical references, a typical 2004 Toyota HiAce sold in Australia and New Zealand does not use steering rack boots. Toyota’s Electronic Parts Catalogue (EPC) for the late H100-series HiAce (the shape sold locally up to 2004) lists a recirculating-ball steering box with a pitman arm, relay rod and idler arm rather than a rack-and-pinion assembly. Gregory’s and Ellery’s service manuals covering HiAce up to 2004 back this up, describing the steering gear as a box-and-linkage layout with no bellows-style rack boots. By contrast, the next-generation H200 HiAce (introduced locally from 2005, and in some markets late 2004) moved to rack-and-pinion steering, which does use rack boots on each end of the rack.

So for most AU/NZ-market 2004 HiAce vans, “rack boots” aren’t relevant because there isn’t a steering rack to boot. Instead, the components that wear and need attention are the tie-rod ends, relay rod ends, idler arm bush/bearing and the steering box itself. Those parts have their own dust boots or seals, but they’re different to the accordion-style bellows seen on rack-and-pinion setups.

There are exceptions. A late-2004 import that’s actually the newer H200 shape can be fitted with a rack-and-pinion and will have rack boots. If there’s any doubt, a quick look under the front will tell the story.

• If it has a steering box on the driver’s side with a short pitman arm linking to a long relay rod across the front, it’s the H100 style — no rack boots fitted.
• If it has a straight rack tube running across the crossmember with an accordion rubber boot (gaiter) at each end, it’s a rack-and-pinion H200 — rack boots are fitted and should be intact.

For owners of the 2004 H100 HiAce, good steering maintenance during servicing means checking free play at the wheel, inspecting tie-rod ends and the relay rod for split dust boots or looseness, checking the idler arm for slop, and making sure the steering box isn’t weeping fluid at the input/output seals. Keep an eye on front suspension bushes and wheel alignment too, as they affect steering feel and tyre wear just as much as the linkages.

If yours turns out to be a late-2004 H200 with rack-and-pinion, treat the rack boots as critical dust and fluid guards: if a boot is torn or oily, replace in pairs, clean the inner tie rods, and re-grease per workshop procedure. After any boot or inner tie-rod work, a proper wheel alignment is a must.

Popular questions about 2004 Toyota HiAce rack boots

Does a 2004 Toyota HiAce have rack boots from factory?

For most Australian and New Zealand 2004 HiAce vans (H100 shape), no — they use a recirculating-ball steering box and linkages, which don’t have rack boots. Only the newer H200 shape (arriving locally from 2005, and in some markets late 2004) runs rack-and-pinion steering with bellows-style rack boots.

If the van is a late-2004 import and looks like the H200, check for the accordion boots on each end of a straight rack tube. If they’re there, it has rack boots that need periodic inspection.

How can someone tell if their 2004 HiAce is H100 or H200 for steering parts?

Look underneath the front: a steering box with a pitman arm and long relay rod means H100 (no rack boots). A straight rack housing with bellows boots at each end means H200 (rack boots fitted). Body shape is a giveaway too — the H200 has a squarer, wider nose and more modern dashboard.

The build plate and VIN decode will also confirm the series. When ordering parts, quoting the VIN and production month helps avoid mixing H100 linkage parts with H200 rack components.

What steering maintenance should be done if there are no rack boots?

On the 2004 H100, focus on tie-rod ends, relay rod ends, idler arm play and the steering box for leaks or excess free play. Replace any split dust boots promptly to keep grit out, and get the wheel alignment checked after steering work to protect tyre life.

Regular servicing should also include checking front suspension bushes and wheel bearings. Any vagueness at the wheel or knocking over bumps is a cue to inspect the linkage joints and idler arm assembly.
