Cardan drive shafts and BMW's Power transmission are two of the most important parts of this vehicle. Without either one, your ride would be incomplete. BMW's power transmission can be your first stop when your ride breaks down.
No one is perfect, but if you are looking for a great power feel, the cardan drive shafts can work wonders. If you have it, that is good, but if you don't, there is not much that BMW can do to help you. I'm not even sure what they can do if you have a faulty Cardan Drive Shaft or Front Drive Shaft, especially when it comes to the three wheels that make up the steering wheel.
The one problem with BMW's Power transmission is that it isn't perfect. The day you think you are without trouble is the day you really begin to have trouble. The reason is that every car, no matter how big or small, has some form of a power steering failure.
For numerous BMW drivers, this is not a minor failure. They are caught in traffic, trying to get around an accident or make a turn and suddenly the steering feels like it is bent.
To be able to tell if it is cardan drive shafts or BMW Power transmission failure, you must identify the source of the problem. One simple test you can use is to push on the wheel at the bottom of the steering column. It should stop after some force has been applied.
If the wheel doesn't stop at all, you may be dealing with a cardan drive shafts issue. If you pull on the wheel, it should stop after some force has been applied.
The reason the wheel doesn't stop is that this power steering part is meant to grip the pavement and not the side of the vehicle. If you start having trouble with the power steering on the bottom, the driver's side of the vehicle, you may be dealing with a Cardan Drive Shaft issue. If you start having trouble with the front or top of the vehicle, that could be a BMW Power Steering issue.
Some drivers, though they may look like they are perfectly fine, are experiencing problems with their BMW's power steering that are costing them money and are ruining their driving experience. If you take a look at your steering wheel and feel that the grip it has is lacking, chances are you could be dealing with a broken or damaged cardan drive shafts.
The bottom line is that if you haven't been having problems with the power steering, it is a Cardan Drive Shaft issue. If you find yourself struggling, you may need to deal with this part on the front or top of the vehicle.
If you find a replacement part doesn't fit properly, it may be time to call BMW, too. You never know if your repair will cost more than you made in insurance premiums.
Some of the cardan drive shafts issues arise because the vehicle's bodywork is not as strong as it should be, or it isn't painted to allow for the proper body style. Cars that have had bodywork damage have been known to suffer from different BMW problems as well.
To put it simply, cars that break down because of problems in the bodywork are causing you to have long nights looking for a workable part, whether it is the cardan drive shafts or something else. If this sounds like your issue, you should contact BMW to determine what to do.
