How Much Does Crankshaft Bearing Replacement Cost in UAE?
Crankshaft bearing replacement in the UAE costs between AED 800 and AED 4,500 in 2026. The wide range reflects differences in engine type, the number of bearings replaced, and whether the crankshaft requires machining. Japanese and Korean four-cylinder petrol engines are at the lower end. V6 and V8 engines in European and American vehicles are at the higher end.

What Are Crankshaft Bearings?
Crankshaft bearings are precision-machined half-shell inserts that sit between the crankshaft journals and the engine block (main bearings) or connecting rods (rod bearings). They provide a thin pressurised oil film that allows the crankshaft to rotate at high speed with minimal friction. When the oil film breaks down due to low oil pressure, oil starvation, contaminated oil, or bearing wear, the bearing surfaces contact the crankshaft and cause progressive damage to both components.
Symptoms of Worn Crankshaft Bearings
- Deep knocking or rumbling from the lower engine that increases with engine speed
- Low oil pressure warning light on the dashboard
- Engine noise that worsens under load (accelerating or climbing)
- Metallic particles in the engine oil on inspection
- Oil pressure gauge reading below the normal range at operating temperature
What Happens During Crankshaft Bearing Replacement?
The mechanic drains the engine oil and removes the sump (oil pan) to access the crankshaft. The connecting rod caps and main bearing caps are removed in sequence, and the old bearing shells are extracted. The crankshaft journal surfaces are measured with a micrometer to determine whether they are within tolerance or require machining. If the journals are within tolerance, new bearing shells of the correct size are fitted, the caps are reinstalled, and the fasteners are torqued to specification. The sump is refitted with a new gasket and fresh oil of the correct grade is added. On engines with significant journal wear, the crankshaft must be removed for grinding at a machine shop before new oversized bearing shells are fitted.
How to Get the Best Price for Crankshaft Bearing Replacement in UAE
- Get a compression and oil pressure test before authorising the repair to confirm bearings are the root cause
- Ask whether the crankshaft journals have been measured and whether machining is needed
- Request OEM-equivalent bearing shells for long-term reliability
- Replace both main and rod bearings together if the engine has high mileage
- Use GarageBuddy to compare quotes from certified garages across UAE emirates
