Parts for your 2000 Subaru Legacy-Cv joint

2000 Subaru Legacy CV-joint: what it does, why it matters, and when to service it

Based on technical sources, a cv-joint is absolutely relevant to the 2000 Subaru Legacy. The Subaru Factory Service Manual for the BE/BH series (2000 model year) details front drive shafts with a Birfield-type outer CV joint and a Double Offset Joint (DOJ) inner CV, with similar constant-velocity joints on the rear half-shafts in AWD models. This is echoed by Subaru’s Technical Information System materials, common aftermarket repair manuals (e.g., Haynes), and the Subaru electronic parts catalogue, which lists complete front and rear CV axle assemblies for the 2000 Legacy. So yes—this vehicle is fitted with CV joints at each driven wheel.

On a 2000 Legacy, the cv-joint lets the driven wheels put power down smoothly while steering and moving up and down with the suspension. The outer Birfield joint manages steering angle without shudder, while the inner DOJ allows plunge (in–out movement) as the suspension travels. In normal use you shouldn’t notice them at all—that’s the point—just quiet, vibration-free drive.

As part of regular servicing, CV joints deserve a quick once-over every service or 10,000–15,000 km. The rubber boots are the big tell. If a boot splits, grease flings out and road grit gets in, and the joint can start clicking on turns or humming under load pretty quickly.

• Look for torn or perished boots, grease spray on the inner guard, and cracked clamps.
• Listen for a rhythmic click on full lock (usually outer joint) or vibration under acceleration (often inner joint).
• Check axial play and boot condition with the wheels off the ground.

If a boot is torn but the joint hasn’t started to click, a prompt boot-and-grease service can save the axle. Once it clicks, replacement of the affected axle or joint is the reliable fix. On many 2000 Legacys the front inner joint is pinned to the transmission stub with a spring pin, the outer end uses a large axle nut at the hub—both must be removed and reinstalled to factory procedure. Always use the correct moly CV grease, new boot clamps, new spring pin (where fitted), and torque the axle nut to the factory spec from the Subaru FSM. After refit, a wheel alignment check is a good shout to keep tyre wear even.

Quality reman or genuine axles last well if installed right. Keeping the boots healthy is the easiest way to avoid pricey driveline work down the track.

Popular questions about 2000 Subaru Legacy CV-joints

How do I tell if my 2000 Legacy needs a CV-joint or axle replacement?

Common signs include clicking when turning at low speed (outer joint), vibration on take-off or at motorway speeds (often inner joint), or visible grease flung around the wheel well from a split boot. If the joint clicks, the axle usually needs replacement, if only the boot is torn and there’s no noise, a boot kit and fresh grease may suffice.

Should I replace both front axles at the same time?

Not mandatory, but it’s common to replace the noisy or worn side only. If the other side’s boots are aged or starting to crack, doing both can save labour later. Always use quality parts and follow the Subaru FSM procedures and torque specs.

Can I drive with a torn CV boot for a while?

It’s risky. Once the boot is torn, grease escapes and contamination gets in, accelerating wear. Short local trips might be okay, but it can go from quiet to clicking quickly. Sorting the boot or axle early usually costs less than waiting for the joint to fail.
