What Is a Limited-Slip Differential (LSD)?
An LSD puts power down where an open diff spins a wheel. A Cranbourne West specialist explains.
What it is & what it does
A standard open differential sends power to the wheel with least grip — fine cornering, useless with one wheel slipping. A limited-slip diff resists that speed difference (via clutch packs, helical gears or an electronic brake-based imitation), driving both wheels out of corners and on loose surfaces.
Performance cars, many utes and off-roaders carry one.
Signs of trouble & how we help
Clutch-type LSDs need their own specific oil (often with a friction additive) and it does wear out — a chattering or shuddering noise on tight, slow corners is the classic sign of tired LSD oil or clutches. Wrong oil creates the same complaint instantly.
We service LSDs with the correct oil and additive, and diagnose diff noises before they grow expensive.

Tired or wrong LSD oil (or worn clutches) — the classic clutch-type LSD complaint, often fixed by the correct oil.
Clutch types do — specific oil, often with friction additive. Wrong oil causes instant chatter.
Performance models, many utes and off-roaders — and some electronic systems imitate one with the brakes.
