Parts for your 2012 Toyota Crown-Cv boots

2012 Toyota Crown CV boots — what they do and when to sort them

Per Toyota technical literature — specifically the Toyota Crown GRS20#/AWS21# Repair Manual (Drivetrain/Axle section) and the Toyota Electronic Parts Catalogue for the Drive Shaft & Axle group — the 2012 Toyota Crown does use CV boots. RWD Crowns run CV-jointed half-shafts with rubber boots at the rear, and i-Four AWD models use CV boots on both front and rear drive shafts. So, yes, CV boots are relevant to this model.

On the 2012 Toyota Crown, the CV boots are the tough, flexible rubber covers that keep high-moly grease around the constant velocity joints and keep grit and water out. That sealed grease bath lets the joints articulate smoothly through suspension travel and steering (on AWD fronts) without vibration or clunks. When a boot splits or perishes, grease gets flung out and road grime finds its way in — that’s when wear ramps up fast and a quiet joint can turn into a clicking, knocking headache.

For routine servicing on a Crown — whether it’s a Royal, Athlete, or Majesta — it’s smart to include a quick CV boot check. A torch and a look behind each wheel is usually enough: they should be intact, pliable, and dry on the outside, with no slung grease on the undertray or arms. Toyota’s workshop procedures call for replacing boots that are cracked, torn, or leaking, and re-packing the joint with the specified grease when a new boot goes on. That’s a tidy, cost-effective save compared with replacing a whole shaft later.

Recommended habits for Aussie and Kiwi conditions:

• Inspect at every service or WOF/Safety Check, and after long gravel trips or beach driving.
• If a boot is weeping, get onto it within a few hundred kilometres — the sooner it’s re-booted and re-greased, the better the joint’s longevity.
• Use quality boot kits and proper stainless clamps, avoid generic cable ties that loosen with heat cycles.

Typical signs it’s time to act include grease spray on the inner rim or underbody, a rubbery smell on hot days, or clicking on take-off or full lock (AWD fronts). Keep the CV boots healthy and the Crown’s driveline stays quiet, smooth, and ready for many more kilometres.

Popular questions

Does the 2012 Toyota Crown have CV boots on all four wheels?
RWD versions have CV boots on the rear half-shafts only. AWD (i-Four) variants have CV boots on both front and rear shafts. This setup is confirmed in Toyota’s Repair Manual and EPC for the Crown’s drivetrain assemblies.

How often should the CV boots be checked?
They’re worth a look at every service or WOF/Safety Check. If the car sees gravel roads, coastal air, or heat-soaked city driving, inspect more often. Early detection of a split boot usually means a simple re-boot and grease rather than a new joint or shaft.

What are the signs a CV boot or joint needs attention?
Look for grease flung around the wheel arch or underbody, visible cracks in the rubber, or a clicking/knocking noise when accelerating or turning (fronts on AWD). Any of these warrants prompt inspection and likely a boot replacement with fresh grease.
