Common Toyota Hilux Differential Problems
Hilux diffs are tough, but they are not bulletproof. These are the faults we see most often across the workshop bench, and how to pick them early.
George Bull, owner 1 min read
The Toyota Hilux has one of the most reliable rear ends on the market, which is exactly why owners tend to ignore it until something is wrong. Most of the Hilux diffs that come through our workshop have been run low on oil or driven with a leaking pinion seal for too long.
The usual suspects
- Pinion seal leaks that drain the housing and cook the pinion bearings
- Crownwheel and pinion wear on high kilometre work utes
- Rear wheel bearing and axle seal failure letting oil into the brakes
Keeping on top of it
A diff oil change every 40,000 km, and a quick look underneath for weeping seals at every service, will pick most of these up early. If you are hearing a whine on the open road, book it in before it becomes a gearset job.
Think your diff is making noise? Around 120 rebuilt exchange diffs on the shelf for 30 plus makes and models. Fitted here in Sydenham, or shipped anywhere in NZ with free freight both ways.
