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.

2003 BMW 525i Reviews
Great car but repairs are expensive. The question is there is no replacement available for it. Find a good independent repair shop as BMW of North America and ALL dealers are a complete joke!! If you find a good repair shop this is a once in a life time car. Around 94595 I would highly recommend European Werkstaat. I would buy it again.
I bought my 525i used from a co-worker with 71,000 miles 4 years ago- I now have 146,000 miles and other than normal maintenance, it is a terrific car and I am happy to have it!
I bought used 2003 525i and it has been a nightmare. Twisted seat, LED display, pulley coming off, cracked radiator, belt replacement, fuel filter, brakes, heated seates, cup holder, headlight, brake light, shocks, loss of hp, service light, leaking oil, leaking power steering fluid and other problems have all be taken place in the short 6 month time I have owned it. No wonder there are so many you-tube videos on how to fix a BMW. I would never recommend a BMW. i am sticking to American Made next time.
No problems for the first 6 years, now they are starting to mount @ only 75,000 miles
