2004 Subaru Forester CV Boots: What They Do and When to Service Them

CV boots absolutely are used on the 2004 Subaru Forester. Technical sources including the Subaru Factory Service Manual (SG Forester, 2003–2005, Driveline/Axle section) and the Subaru Genuine Parts catalogue for MY2004 list inner and outer CV boot kits for the front shafts and boots for the rear drive shafts. The FSM details removal and installation procedures for the boots and joints, confirming they’re standard kit on this symmetrical AWD model.

On a 2004 Forester, each drive shaft uses constant velocity joints that need to stay packed with the right grease and kept free of grit and water. That job falls to the CV boots—flexible rubber sleeves with clamps at each end. They protect the Rzeppa-type outer joints and the double-offset inner joints, so the car can steer, corner and put power down smoothly without clicks, shudders or premature wear.

Because Foresters in Australia and New Zealand often see corrugations, beach runs and muddy tracks, the boots cop a fair bit of movement and road spray. A torn or perished boot quickly flings grease out and lets sand in—bad combo. Typical signs include grease splatter on the inside of the wheel or strut, a rhythmic click on tight turns, or a vibration under load. Catching a split early usually means a boot-and-grease job instead of a full shaft or joint replacement.

Good servicing habits help the boots last:

• Inspect at every scheduled service (around 10,000–15,000 km) or after off-road use.
• Look for cracks, splits, loose clamps and grease seepage.
• If a boot is compromised but the joint’s quiet, fit a quality boot kit and repack with the specified moly CV grease.
• Front boots work hardest, if one has failed, consider doing the pair on that axle.
• If there’s clicking or joint play, a complete shaft may be the better value fix.
• Always use correct clamps and follow the Subaru FSM torque procedures for axle nuts and suspension fasteners.

Done right, fresh boots and grease keep the SG Forester’s AWD smooth, quiet and reliable for heaps more kilometres, whether it’s the daily commute or a weekend gravel sprint.

FAQs

How often should CV boots be checked on a 2004 Subaru Forester?
They’re best checked at every routine service interval (roughly 10,000–15,000 km) and after any heavy off-road or beach driving. Regular inspections pick up small cracks and loose clamps before the grease escapes and grit gets in, saving the joints from expensive wear.

Can a torn CV boot be replaced without changing the whole driveshaft?
Yes—if the joint hasn’t been run dry or started clicking. A proper boot kit with the right moly grease and clamps can restore protection. If there’s noise, roughness, or heavy contamination, a complete shaft or joint replacement is usually the smarter call.

Which grease and specs should be used when servicing Forester CV boots?
Use the specified high-moly CV joint grease supplied in quality boot kits and follow the Subaru Factory Service Manual for the correct quantities, clamp positioning and torque settings. Sticking to the FSM procedures helps avoid repeat leaks and ensures bearing preload and axle nut torque are spot on.
