Parts for your 2017 Mitsubishi Eclipse cross-Cv boots

2017 Mitsubishi Eclipse Cross CV boots: purpose, care and replacement

Based on Mitsubishi Motors service literature and OEM parts catalogues for the 2017 Eclipse Cross (FWD and AWD), the vehicle is fitted with constant-velocity joints on the front driveshafts, each protected by rubber CV boots, AWD variants also carry CV-jointed rear half‑shafts with boots. So CV boots are relevant on this model and are considered standard driveline protection components.

CV boots do a deceptively big job. They keep high‑moly grease packed around the joint while sealing out water, grit and road grime, all while flexing as the suspension moves and the wheels steer. When boots stay intact, the CV joints remain quiet, smooth and long‑lived. When a boot splits, grease is flung out, contaminants rush in, and the joint can wear quickly—often announcing itself with a clicking on full lock or a shudder under acceleration.

For the 2017 Eclipse Cross, boot condition should be checked as part of routine servicing—typically every 10,000–15,000 kilometres, or sooner if the vehicle sees gravel roads, roadworks or coastal exposure. Tell‑tale signs include fine cracks in the rubber, loose or rusty clamps, and grease spray inside the wheel, under the guard or across the subframe. Catching a tired boot early usually saves the joint.

When replacement is required, quality matters. Technicians generally fit OEM‑grade thermoplastic or neoprene boots with stainless clamps and fresh molybdenum disulphide CV grease. Front outer boot service on the Eclipse Cross involves removing the axle nut, separating the knuckle or lower arm and sliding the joint apart for cleaning and re‑greasing. Correct torques on the axle nut and suspension fasteners are critical, and a wheel alignment check is smart if the knuckle or strut bolts are disturbed. AWD models warrant the same attention at the rear.

Cost‑wise, a new boot and grease is far cheaper than a complete driveshaft. If the joint already clicks or has excess play, replacing the joint or the full shaft assembly is the safe bet. Avoid directing a pressure washer at the boots, and after a rough‑road stint, a quick visual under the car can prevent a small split becoming a big bill.

• Service checklist: inspect boots and clamps, clean off old grease spray, check for noise on full lock, and act quickly on any split or weeping.

Popular questions

How often should CV boots on a 2017 Eclipse Cross be inspected?
They’re best checked at every scheduled service or around every 10,000–15,000 kilometres. Vehicles driven on gravel, in heavy rain or near the coast benefit from more frequent inspections, as grit and salt age the rubber faster.

Can a torn CV boot be patched, or does it need replacing?
Patching or taping isn’t recommended. Once a boot has split, it should be replaced and the joint cleaned and re‑greased. Split‑boot “quick kits” are only a short‑term fix, a full boot replacement offers a proper seal and longer service life.

What are the symptoms of a worn CV joint versus just a bad boot?
Grease flung around the inner wheel arch points to a bad boot. If there’s clicking on turns, vibration under acceleration, or noticeable play at the joint, the CV joint itself may already be worn and could need replacement along with the boot.
