Hyundai Mighty Differential Assembly
Whether your Mighty is an early or late build, we match the differential assembly to your derivative rather than to the badge
What Are Hyundai Mighty Differential Assembly?
The differential lets the two driven wheels turn at different speeds through a corner while still both receiving drive. On most of the Hyundai range sold here it is not a separate unit at all — the i10, i20, Getz, Accent, Elantra, Creta and the front-drive Tucson derivatives all carry the final drive inside the gearbox casing, so a "diff" job on those cars is a gearbox job. A standalone differential you can unbolt only exists on the rear-drive and all-wheel-drive Hyundais: the H100, H1, Mighty, Terracan and the AWD Santa Fe and Tucson derivatives. A worn final drive announces itself as a whine that rises and falls with road speed rather than with engine revs — which is how we tell it apart from a tired wheel bearing.
Signs You Need New Differential Assembly
Before you order differential assembly for a Mighty
Does one differential assembly listing cover every Mighty?
No. Ordering differential assembly for a Mighty starts with the generation: the SA-market light-truck range including the EX8.These are chassis-cab trucks bodied after sale, so the cab and driveline come from Hyundai while the load body usually does not — tell us which of the two the part belongs to.
Which engine is in my Mighty?
SA-market cars were sold with the 2.5 turbo-diesel and 3.9 diesel as badged on the SA derivatives. The code stamped on the block settles it — the badge on the boot does not.
What do you need from me to quote differential assembly?
Manual or automatic, the number of gears, and the engine it is bolted to. Manual and automatic derivatives of the same Hyundai take entirely different mountings, driveshafts and coolers, and the automatic itself changed within some generations.
In South Africa the Mighty is mostly distribution and delivery work where downtime is lost income, so demand is overwhelmingly for driveline, clutch and braking parts. That is the wear pattern we stock and source against.
Before You Order Mighty Differential Assembly
Will differential assembly from another Mighty fit mine?
Not automatically. The Mighty sold in South Africa as the SA-market light-truck range including the EX8, and these are chassis-cab trucks bodied after sale, so the cab and driveline come from Hyundai while the load body usually does not — tell us which of the two the part belongs to. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
How do you check differential assembly actually fits a Mighty?
We work backwards from the VIN: generation first, then engine family, then whether the car is pre- or post-facelift within that generation. On the Mighty specifically, these are chassis-cab trucks bodied after sale, so the cab and driveline come from Hyundai while the load body usually does not — tell us which of the two the part belongs to.
Does my Hyundai have a separate differential at all?
Probably not. The i10, i20, Getz, Accent, Elantra, Creta and the front-drive Tucson derivatives all carry the final drive inside the gearbox casing, so what feels like a diff fault is a gearbox job. A standalone diff you can unbolt exists only on the H100, H1, Mighty, Terracan and the all-wheel-drive Santa Fe and Tucson derivatives.
What does a Hyundai differential replacement cost?
Because most of the range runs an integrated diff, replacement usually means a gearbox swap rather than a diff swap. SA used gearboxes range from budget to premium depending on mileage, all available through our supplier network. Send your VIN for a quote and tell us whether the car is manual or automatic.
My Hyundai whines — is that the diff?
Possibly. The tell is what the noise tracks: a worn final drive whines in step with road speed, while a noise that follows engine revs is something else entirely. Worn pinion or crown-wheel bearings hum at low revs; a low gearbox oil level or a worn input-shaft bearing produce something similar. Check the fluid level first — it is a two-minute job and it is free.
Rebuild or replace?
On the integrated units, a proper rebuild with new bearings, crown wheel, pinion and seals often lands at the cost of a good used gearbox, and the used box usually wins on labour hours. On the standalone rear diffs from the rear-drive and 4x4 models, a rebuild makes far more sense.
How often should the gearbox oil be changed?
Hyundai calls the manual gearbox fluid lifetime, but in practice we recommend a change every 60,000 to 80,000 km, and more readily on cars living with SA dust and heat. Fresh gear oil is cheap next to crown-wheel and bearing wear. Raise it at the next service rather than waiting for a noise.
Let us confirm the differential assembly before you buy
Photos of the old part and your VIN are usually all we need. We confirm the differential assembly against your Mighty before quoting, not after.
