BMW 550i GT Car shudders when turning Inspection at your home or office.

Common reasons for this to happen:

• Low Power Steering Fluid: One of the most commonly seen reasons for a shudder during turning is low power steering fluid. If the fluid level is low, the power steering rack and pump don’t have the right pressure to operate. It could also indicate a leak somewhere in the power steering system, which will need to be inspected.

• Failing Power Steering Pump: If your power steering pump is beginning to die, it could very easily cause these symptoms. As the pump fails, it produces less and less pressure for the power steering system, causing vibrations, shudders, whining noises and more.

• Kinked/Blocked Power Steering Line: You need clear power steering fluid lines to ensure the right fluid and pressure distribution. If a line has become blocked or kinked, or is leaking, it can reduce fluid pressure and flow.

• Failing Wheel Bearing: While its most common to experience a roaring noise when a wheel bearing is beginning to fail, they can also cause vibrations that some drivers interpret as a “shudder”.

• Failing Differential: If you have an all-wheel drive vehicle, it may be a problem with the front or center differential. When these begin to fail, they will create a shudder, particularly under the stress and strain of a turn.
