Cool! I hope seeing some other posts (PM in suspension "rebuilding/overhauling" in particular - by mileage or by age, and how many have considered or went through this path).

Guesstimate: more or less 1700 USD (BMW OE parts alone) This is 80% front & rear suspension repair kits.. Mechanical labor (high side), maybe between 3-5 hours per axle (12+hrs min, 15+hrs max).. Alignment not included.

* Wheel suspension joint
* Tension struts (with rubber mounting)
* Swing & Stabilizer support
* Various Wishbones
* Ball Joint
* Integral & Stabilizer Link
* New Screws/Nuts/Washer
