• If the suspension strut is not lowered on the above-mentioned sport suspensions when removing the wheel bearing unit/wheel bearing housing from the drive axle and the suspension strut is pulled outward, the deep-groove ball bearing will slide out of the suspension strut mount -2- locking mechanism -arrow-.
• When installing, the deep-groove ball bearing cannot get back into the strut mount locking mechanism, from which noises may occur and the deep-groove ball bearing will be damaged due to contamination.
