How much does it cost to replace the timing chain on a Lexus LS 460?
The replacement typically costs about $1,500 to $3,000 in the United States, though dealer quotes can rise higher, sometimes surpassing $4,000 depending on the year and specific engine configuration.
The timing chain job on a Lexus LS 460 is a major repair that can involve removing substantial engine components. Accessing the chain often requires removing belts, the timing cover, and possibly the water pump, while replacing the chain itself goes hand in hand with new guides, tensioners, and seals. Prices vary by model year, engine variant, regional labor rates, and whether OEM or aftermarket parts are used, making quotes widely variable.
What drives the cost
Several factors determine how much a timing chain replacement will cost on the LS 460.
- Parts costs: A timing chain kit with guides, tensioners, and related seals is essential, and opting for OEM Lexus parts increases the price versus aftermarket equivalents. Water pumps or other auxiliary components may also be replaced as part of the service.
- Labor hours and rate: The LS 460’s timing chain service is labor-intensive. Independent shops generally charge lower hourly rates than dealers, and total hours can range broadly depending on the exact engine variant and accessibility.
- Vehicle year and engine variant: The LS 460 has multiple model years and engine configurations; some layouts are more complex to access, which affects both parts availability and labor time.
- Additional components replaced: Many technicians replace water pumps, pulleys, thermostats, and gasket sets during a timing chain job to reduce the chance of future failures, adding to the total cost.
- Diagnostics and incidental issues: If wear is found beyond the chain itself (e.g., worn guides or damaged seals), quotes may increase to cover the extra work.
In practical terms, independent shops often fall in the $1,500 to $3,000 range for a timing chain replacement, while dealer estimates tend to run higher, sometimes $2,500 to $4,500 or more, especially if OEM parts are required or additional maintenance is recommended at the same time.

Summary
The cost to replace the timing chain on a Lexus LS 460 varies widely based on the engine variant, year, parts choices, and where you go for service. Expect a ballpark range of $1,500–$3,000 at independent shops and $2,500–$4,500 or more at dealerships, with higher totals possible if additional components like the water pump or seals are replaced. Always secure a written estimate that itemizes parts and labor before authorizing work, and consider getting a second quote to compare options.
