F25 Shock absorber replacement Rough Ride

ClampThurst · 05-30-2022, 10:17 PM

Hey all, I recently replace all 4 shocks since as one was leaking at 75k miles on a 2017 X3 3.5i. This is a non sport model/non dynamic suspension control. I used bmw original branded shocks in the real and OEM in the front (all part numbers match non sport model). It's also sitting on brand new Michelin Primacy non-runflats that supposedly have a smooth ride.

I've noticed the ride quality has not returned to "factory smooth" and is quite rough, I feel every bump now almost as if I have sport suspension all of the sudden. Has anyone experienced this firming up after shock replacement???

I can imagine that worn out shocks would probably be a little mushy and that there would be a contrast in ride after replacement but was not expecting it to be this rough/stiff.

Did you replace any of the bushings too? Did you inspect to make sure none of the springs were cracked?

No cracks on springs. All strut mounts and control arm/bushings were replaced with OEM.

You indicated new tires. Have you checked for proper inflation pressure? I recently bought new tires and found the mounting shop inflated all of them to 47psi.

Highly unlikely but I wonder if the mismatched oe vs oem hardware is causing an issue.

Thinking maybe there was some sort of a mismatch of the parts.
