Parts for your 2002 Subaru Forester-Rack boots

2002 Subaru Forester rack boots: purpose, servicing and replacement

Yes—rack boots are used on the 2002 Subaru Forester. Technical sources back this up: the Subaru Factory Service Manual for MY2002 Forester (Steering section, ST) diagrams the steering gearbox bellows (rack boots) on both ends of the rack-and-pinion, the Subaru Electronic Parts Catalogue lists the steering rack bellows/boot for this model, and general repair manuals (e.g., Haynes for Subaru Forester/Impreza) include inspection and replacement of these boots as routine maintenance.

On a 2002 Forester, the rack boots are the concertina-style rubber bellows that seal each end of the power steering rack. Their job is simple but critical: keep grit, water and road muck away from the inner tie rod joint and rack shaft, while letting the rack breathe as it moves. When they split or harden, dirt and moisture get in, chewing out the inner seals and rack gear in no time—then you’re staring down the cost of a reconditioned rack rather than a quick boot swap.

As part of regular servicing in Aussie and Kiwi conditions, have the rack boots inspected every service or 10,000–15,000 kilometres. A WOF/rego check will often flag them too. Watch for perished rubber, loose or missing clamps, visible splits in the bellows, and any oily weeping that hints at a power steering rack seal leak. If one boot’s torn, treat it as urgent—replace the pair so wear stays even and moisture doesn’t ping-pong from side to side through the rack tube.

Quality matters here. Choose OE or OE-equivalent boots that flex cleanly lock-to-lock without kinking. A light smear of suitable grease on the inner tie rod ball is fine, but don’t pack the boot with grease—Subaru’s own guidance is conservative. Make sure the boot’s breather path is open and the clamps are correctly tensioned with a proper banding tool rather than a cable tie bodge.

• Tell-tale signs: split bellows, dirt inside the boot, oily residue, or a light knock over bumps from a worn inner tie rod after running without a seal.
• Replacement tips: count tie rod end turns and mark threads, but still get a wheel alignment—front toe will shift. While you’re there, check inner tie rod play and the rack for leaks. After refit, bleed the power steering by turning lock-to-lock with the front wheels off the ground, then top up the correct ATF fluid and recheck after a short drive.

For competent DIYers with stands and the right spanners, this is a reasonable driveway job. If any doubt, a local mechanic can sort it quickly and save the rack from an early retirement.

Popular questions about 2002 Subaru Forester rack boots

Do I need a wheel alignment after replacing rack boots?
Yes. Even if the tie rod end is counted back onto the same number of turns, the front toe can still end up out. A proper alignment avoids uneven tyre wear and vague steering. It’s cheap insurance after any work that disturbs the tie rods.

Is it safe to drive with a torn rack boot?
Short term, it might feel fine, but every wet day or dusty road feeds grit into the rack. That accelerates inner tie rod wear and can damage the rack seals, leading to leaks. Best move is to replace the boot promptly to avoid a much bigger bill.

What causes rack boots to fail on these Foresters?
Age-related rubber hardening, heat from the engine bay, and constant flexing are the main culprits. Off-road use, road debris, or incorrect clamps can also nick or stress the bellows. Using quality boots and proper clamps helps them last longer.
