Oil leak repair, suspension work and four-wheel alignment
Rolls-Royce Ghost: oil leak repairs, suspension arms and alignment
This Ghost came in for engine oil leaks and suspension noise. We removed the engine and transmission to repair concealed leak areas and replaced the engine oil pan. We also replaced suspension arms to address the noise, then measured and adjusted all four wheels. The post-work check confirmed that no oil leaks were present.
Job Summary
| Vehicle | 2014 Rolls-Royce Ghost |
|---|---|
| Initial inspection | 3 November 2021 · 89,018 km |
| Follow-up work | 15–21 December 2021 · 91,030 km on 15 December |
| Findings | Oil traces around the oil pan and joints; suspension noise; front toe and rear camber required adjustment |
| Work | Engine and transmission removal for oil leak repair, engine oil pan and suspension arm replacement, wheel alignment |
| Result | No oil leaks found after the work · rear camber difference 0.37° → 0.01° · thrust angle −0.09° → 0.00° |
In this case
01
Caring for the refinement of a Ghost
The Ghost combines Rolls-Royce refinement with a more compact body than the Phantom. The first generation debuted in 2009; this vehicle is a 2014 model.
A rare luxury car needs attention beyond its appearance. Checking for oil leaks and measuring wheel alignment helps establish the work the vehicle actually needs.

02
Oil traces beneath the engine
We inspected the engine bay and underbody on 3 November 2021 at 89,018 km. Oil traces were visible on the oil pan surface and around the joints.
Leak diagnosis involves following the path of the oil. Assuming the oil pan is the source simply because oil is visible at the bottom can miss the actual cause.
We also examined fluid traces around a suspension arm bushing and the condition of the rubber. The odometer read 91,030 km during the follow-up work on 15 December.
03
Repairing rear-engine leaks and replacing the oil pan
We removed the engine and transmission and separated the torque converter to reach the rear of the engine. We repaired the normally concealed leak areas and replaced the engine oil pan.
We also examined the interior and mating surfaces after removing the oil pan and surrounding covers. Access depends on the leak location, so the inspection findings determined the scope of dismantling and repair.
04
Suspension arm replacement alongside the oil leak repairs
We compared the removed covers and gaskets and examined the oil pan interior and mating surfaces.

We checked the filter and replaced suspension arms to address the noise. After checking their installation, we measured and adjusted the alignment of all four wheels.
05
Adjusting front toe and rear camber
After the engine and transmission removal work and suspension arm replacement, we measured alignment on 21 December. This checked wheel alignment after the components had been removed and refitted. Front toe was 2.5 mm left and 2.4 mm right, above the range displayed by the equipment. It was adjusted to 1.2 mm and 1.3 mm.
Rear camber was −2.08° left and −1.71° right. Adjusting it to −1.69° and −1.68° reduced the side-to-side difference from 0.37° to 0.01°.
Rear toe changed from −1.0/1.1 mm to 1.3/1.3 mm. The thrust angle, which describes the rear axle’s direction of travel, changed from −0.09° to 0.00°. The diagram and original measurement screens below show the individual changes.

06
Leak checks and wheel alignment before handover
The work combined rear-engine oil leak repairs, engine oil pan replacement and suspension arm replacement to address the noise. We then adjusted front toe, rear camber and rear toe, completing four-wheel alignment before handing the car back.
The post-work check confirmed that no oil leaks were present.
Maintaining a luxury car starts with understanding its present condition. Model-specific inspection and post-work checks belong in the maintenance plan alongside component replacement.
NHC Motors provides the same care for other imported and Korean vehicles. We inspect each model according to its construction and requirements, then explain the work needed and the reasons for it.

Does every oil leak require transmission removal?
No. The leak location and surrounding condition are inspected first. On this Ghost, we removed the engine and transmission and separated the torque converter to repair leaks at the rear of the engine. The necessary scope depends on the vehicle and the diagnosis.
Which components were replaced on this car?
The engine oil pan was replaced as part of the oil leak repairs, and suspension arms were replaced to address the noise. The post-work check found no oil leaks, and wheel alignment was completed before handover.
Why check alignment after suspension work?
Alignment should be checked after engine or suspension components are removed and refitted. After the suspension arms were replaced on this Ghost, measurements confirmed the need to adjust front toe, rear camber and other alignment settings.
Do you only service cars such as Rolls-Royces?
Other imported and Korean vehicles are welcome. The same attention to inspection and post-work checks is applied according to each model’s construction and requirements.
