Parts for your 1999 Ford Falcon-Rack boots

Verdict: rack-boots are fitted to the 1999 Ford Falcon (AU Series). This model runs a power-assisted rack-and-pinion steering gear with bellows-style boots (also called rack gaiters) on each end. This fitment is documented in the Ford AU Series Workshop Manual (Steering), covered in Ellery’s/ Gregory’s service manuals for the AU Falcon, and supported by Australian parts catalogues from major suppliers listing AU-specific steering rack boots and boot kits.

1999 Ford Falcon rack-boots: purpose and care

On a 1999 Falcon AU, the rack-boots shield the steering rack’s inner tie rod joints and rack bar from grit, water and road grime. They act like flexible bellows, expanding and contracting as the rack moves while keeping grease in and contaminants out. On power-steering cars like the AU, a torn boot can let muck chew out the inner joint and can even hide a failing internal rack seal if power-steering fluid starts pooling inside the boot.

Why bother replacing them? Because split or perished boots can fast-track wear on the rack and inner tie rods, lead to vague steering, clunks over bumps and uneven tyre wear. They’re also a common WOF/roadworthy fail point. Rubber ages with heat, oil mist and UV, so even low‑kilometre cars can crack boots as they get on in years.

• Signs they need attention: visible cracks or splits, loose or missing clamps, wet, oily boots (possible rack seal leak), clicking or play when rocking the wheel, accelerated inner or outer tyre wear.
• Service tip: inspect both boots every service while the front end’s in the air. Squeeze the bellows—if you feel fluid sloshing, the rack may be leaking internally.

Replacement is straightforward with the right tools. Mark the tie-rod position, pop the outer tie-rod end from the knuckle, slide the old boot off, clean the rack bar and inner joint, then fit a quality boot with proper clamps (avoid cable ties). Lightly re-grease the inner joint if specified by the kit, ensure any breather/vent routing is correct, refit the tie-rod end to your marks and finish with a professional wheel alignment.

Use reputable AU-fit boots (rubber or neoprene) and replace in pairs to keep steering feel even. If a boot is filled with power-steering fluid, plan for rack seal repair or a replacement rack—boots alone won’t fix a hydraulic leak. Done right, fresh boots help the AU’s steering stay tight, quiet and reliable for many more kilometres.

• Recommended intervals: inspect every service, replace at the first sign of damage or oil contamination.
• Common brands and sources noted in Australian catalogues include Kelpro and equivalent boot kits listed for AU (1998–2002).

Popular questions

How often should AU Falcon rack-boots be replaced?
There’s no fixed kilometre limit—inspect at every service and replace as soon as cracks, splits or oil contamination show up. In mild conditions, quality boots can last many years, but cars driven on gravel or in heat may need them sooner.

Is it safe to drive with a torn rack-boot?
Not ideal. Dirt and water can get into the inner joint and rack, accelerating wear and potentially causing steering play. If the boot is wet with power-steering fluid, the rack may be leaking internally—book repairs promptly.

Are AU rack-boots the same across all 1999 Falcon variants?
Most AU I models share the same style of rack-boot, but always check by VIN or build date. Aftermarket listings often cover AU 1998–2002, yet clamp sizes and boot length can vary between brands.
