Is it dangerous to keep driving with a whining differential?

Not immediately dangerous, but continuing to drive without repair risks the gears failing completely, which can be far more expensive to fix — have it inspected promptly.

How often should differential fluid be changed?

There’s no universal interval — check the manufacturer’s service schedule, though it’s often less frequent than engine oil changes.

What is the differential made of?

A cast iron or aluminium housing containing hardened steel gears.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
