Parts for your 2012 Subaru Exiga-Cv boots

2012 Subaru Exiga CV boots — what they do and when to sort them

Technical sources such as the Subaru Exiga (YA) Factory Service Manual (Front Axle and Rear Axle/Drive Shaft System) and the Subaru FAST electronic parts catalogue for the 2012 Exiga confirm that front and rear drive shafts with constant-velocity joints are used, and each joint is protected by a CV boot. So yes — CV boots are absolutely fitted to the 2012 Subaru Exiga.

On a 2012 Subaru Exiga, CV boots are the flexible rubber sleeves that seal each CV joint and keep high‑moly grease in while keeping water, dust, and road grit out. Because the Exiga runs Subaru’s Symmetrical AWD, it has multiple CV joints working up front and at the rear. Those joints allow smooth power delivery while the suspension moves and the wheels steer, which means the boots cop constant flexing and the odd splash of grime, salt, and heat from nearby exhausts.

Keeping the boots in good nick protects the CV joints themselves. Once a boot splits and flings grease, a joint can run dry and start clicking on turns or vibrating under load. Left too long, that can turn a simple boot job into a full driveshaft or CV joint replacement.

• Common signs of trouble: grease sprayed around the inner wheel or lower control arm, visible cracks in the rubber, a tell‑tale click when turning, or a shudder on take‑off.
• Service tip: include a CV boot check at every routine service (around 10,000–15,000 km), or sooner if driving on gravel, coastal roads, or through floodwater.

When replacement’s needed, quality matters. Use OE‑style neoprene or TPE boots with stainless clamps and the correct molybdenum CV grease. Clean out the joint if any grit got in, and make sure clamps are tensioned properly so there’s no weeping. On the Exiga, both inner (DOJ) and outer (BJ) boots are serviceable, many techs prefer rebooting a good joint rather than swapping the whole shaft, which saves dollars and keeps the factory shaft in place.

A tidy boot job should seal perfectly, flex smoothly, and show no grease sling after a short test drive. If a boot has been split for a while or the joint clicks under load, it’s worth pricing a joint or complete shaft — it can be the more reliable fix in that case. Keep an eye on the right‑hand front inner boot in particular, heat from the exhaust can age it faster on some Subarus. Look after the boots, and the Exiga’s AWD driveline will stay quiet, smooth, and drama‑free for heaps of kilometres.

How often should CV boots be inspected on a 2012 Subaru Exiga? It’s smart to have them checked at every scheduled service, roughly every 10,000–15,000 kilometres in Australia and New Zealand. If the Exiga does lots of coastal, gravel, or wet commuting, ask for a quick look between services as well. Early detection of small cracks prevents bigger spend later.

What are the signs a CV boot has failed on an Exiga? Look for grease splattered on the inside of the wheel or suspension, a visible tear in the boot, or a clicking noise on tight turns. If caught early, a reboot and fresh grease usually sorts it. If it’s been noisy for a while, the CV joint may need replacing.

Can just the boot be replaced, or does the whole driveshaft need to go? If the joint isn’t worn, replacing only the boot with the correct grease and clamps is perfectly fine and often the most cost‑effective option. If the joint has run dry or clicks under load, a new joint or complete shaft is the better long‑term fix.
