Riding Height

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2007 BMW 550i, 2007 BMW 530i, 2007 BMW 525i, 2006 BMW 550i, and 2006 BMW 530i. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Riding height may be affected by faulty electronic suspension system. If height is not correct, see appropriate ELECTRONIC article.
NOTE: Letters and numbers in text refer to letters and numbers in figures.
NOTE: To identify installed spring, refer to parts microfiche, contact parts supplier, or remove spring and find BMW number on end of spring. Springs are allocated by vehicle type and, where applicable, by special equipment such as air conditioning, sports suspension, etc. and by date of production launch.
  1. Ensure vehicle is on a level surface. Place front seats in center positions and load each with 150 Lbs. (68 kg). Load center of rear seat with 150 Lbs. (68 kg). Load luggage compartment with 46 Lbs. (21 kg). Ensure fuel tank is full.
  2. Determine actual ride-level height (A) by measuring from wheel arch lower edge (1) to rim flange (2) at wheel center height. See Fig 1. Bounce vehicle up and down. Determine average value for each wheel and establish average value for axle.
  3. For ride height specifications. See RIDE HEIGHT SPECIFICATIONS .
  4. If ride height is not to specification, replace both coil springs even though only one may be defective. See STRUT WITH COIL SPRING  under REMOVAL & INSTALLATION.
