A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

BMW 740i Problems
Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.
The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps. These worn bushings should be replaced.
Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.
The rear lower ball joints may wear causing alignment and tire wear issues as a result of the excessive play in these joints. Our technicians tell us a 4wheel alignment should be performed after ball joint replacement.

IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING.

I purchased my 1998 740i in 2005 with 69K. I was hesitant about buying a car online. I had to fly 900 miles to pick up the car. That 900 mile drive back home convinced me that BMW is the “Ultimate Driving Machine.” At one point I was driving and bonding with the car, then I looked at the speedometer and I was going 105 mph. (That’s how we roll in Texas). I couldn’t believe that I was driving that fast. The point is that there was no rattling; no shaking; no vibrations just exhilaration. This is not the car for you if you are on a serious budget. I was fortunate to find a certified BMW mechanic who started his own business to care for my car which saved me a lot on labor but the parts were somewhat pricey even online. I recently traded my 98 with 90K for a 2001 740i with 43K. I was going to save my pennies and purchase a 2009 in 2016 but I just couldn’t pass up this car with that mileage. My new Bimmer and I are getting to know each other but if this one is like my 98 it’s going to be another great relationship.
My alarm will come on while i am driving and don't know what to do In need of any kind of help
I love my 1995 740I. Over 250,000 miles and it still runs like a dream. I am noticing noises in the front when I go over speed bumps and or pot holes it seems to happen only when the front end moves up and down. I would like to see apicture of what possibly needs to be eplaced.
Any help would be greatly apreeciated.
Looking for some help. I have a 1998 740i. The soft close mechanism for the trunk has stopped working. The switch to open the trunk located inside the car on the driver's side will not work. The trunk button on the key will not open the trunk. The trunk will open by using the key in the trunk lock will open it. Any help will be appreciated. Thanks in advance.
