XC90 FWD L6-3.2L VIN 96 B6324S2 (2010)
A new screw (note 10 in picture in the attachment) with wider waist was introduced in production during structure week 2008w40 (chassis 512712) to
maintain a better connection.
A new control arm with a narrower bushing tube was introduced in production during structure week 2009w21 (see chassis range above). This bushing
will minimize the play to only 0.5 mm (0.02") when using it with the new screw. The screw and the bushing are available as spare parts.
First carry out basic analysis to understand where the noise is coming from. If possible use the Chassis Ear tool kit.
Only for cars before chassis number 532770:
If the noise is determined to be coming from the rear bushing of the front control arm replace the rear bushing (PN 31304040) the screw (PN 999403)
and the nut (PN 985660) on both sides according to VIDA:
Removal replacement and installation
Suspension and steering
Front wheel suspension
Front axle crossmember control arm
Bushings link arm replacing
It is very important to tighten the nut to the proper torque found in VIDA!
