    noise in the steering


    Check the top of the front suspension spring towers while someone turns the wheel. You may feel or hear a grinding if the bearing is shot. The top of the spring retainer has a bearing to allow the strut to turn and can be the cause.


    A new replacement part from BMW is almost as exoensive as a house so try for a used one or get a set of adjustable ones from K-Mac Suspension (Australia) they are much cheaper and allow seperate camber and caster adjsutment which thwe factory stuff won't. There are dealers worldwide.

  • 840 Gearshift RPMs

    Can anyone tell me at what RPM an 840 5 speed should upshift at wide open throttle?


    The Tacho calibrations show broken orange warnings from 6000 to 6500 then its orange all the way suggesting redline, or what I believe to be the high end upshift. Mine changes at about 6600/6700 so I wonder if the trans computer has been modified. My dealer doesnt have a friggin clue but he did suggest that some 840s had a bad control map and that when dealers do a rebuild that they reprogram the TCU.


    Any clues or stories of your own change points?
