Parts for your 2009 Mitsubishi Lancer-Cv boots

2009 Mitsubishi Lancer CV boots — purpose, checks, and when to replace

Yes, CV boots are used on the 2009 Mitsubishi Lancer. Technical references including the Mitsubishi Lancer CJ Workshop Manual (Group 26 – Front Axle/Driveshaft), the Mitsubishi ASA electronic parts catalogue, and third‑party service data such as Haynes/Autodata all specify inner and outer CV joint boots fitted to the front driveshafts on FWD models, with additional rear axle boots on AWD/Ralliart/Evolution variants. So they’re absolutely relevant to servicing a 2009 Lancer.

On this model, the CV boots are flexible rubber or thermoplastic sleeves that seal each constant velocity (CV) joint. They hold the correct amount of moly grease inside the joint and keep out water, grit, and road grime. That grease is what lets the joint articulate smoothly during steering and suspension travel without binding, so intact boots are essential for quiet, vibration‑free driving and long joint life.

Age, heat from the brakes, steering angles, and ozone exposure eventually harden and crack boots. Once a boot splits, grease is flung onto the inside of the wheel and the joint runs dry, often leading to clicking on turns and premature joint wear. Leaving a torn boot too long usually turns a simple boot job into a whole driveshaft or CV joint replacement.

Best practice for a 2009 Lancer is to have the CV boots inspected at each regular service interval (every 10,000–15,000 km is common in AU/NZ schedules). A quick torch check of the inner (transmission side) and outer (wheel side) boots for splits, loose clamps, or grease spray can save a lot of coin.

• Typical signs: grease on the inner rim or control arms, a burning‑grease smell after a drive, or clicking when turning under throttle.
• If a boot is torn but the joint is quiet, a boot‑only replacement with fresh moly CV grease and new clamps is usually fine.
• Use quality OEM‑spec boots and stainless clamps, avoid generic thin boots on Aussie/Kiwi roads.
• Correctly torque the axle nut and suspension fasteners. An alignment isn’t normally needed unless strut or arm bolts are loosened.

There’s no fixed replacement age, but many owners see original boots last well beyond 100,000 km if inspected and kept clean. Avoid pressure‑washing directly at the boots, and sort any seep or clamp looseness early. For AWD Lancer variants, remember there are more boots to check, front and rear.

Popular questions

How long do CV boots last on a 2009 Mitsubishi Lancer?

With regular checks, good quality replacements, and no accidental damage, CV boots commonly last 100,000–150,000 km or more. Heat, rough roads, and age can shorten that. Catching small cracks or loose clamps at a routine service helps them go the distance.

Can a split CV boot be taped or glued?

Temporary wraps or glue rarely hold under rotation and heat. If the split is fresh and the joint is still quiet, a proper boot replacement with new grease and clamps is the reliable fix. Driving far with a torn boot risks joint damage and a pricier repair.

Do AWD Ralliart/Evo Lancers have more CV boots to maintain?

Yes. AWD models add rear driveshafts with their own CV joints and boots. The inspection approach is the same—look for cracks, loose clamps, and grease spray—but you’ll have more boots to check at each service.
