Vehicle strut assembly
A vehicle strut assembly includes at least a strut member, a bearing assembly, a mounting bracket and a noise isolating member. The bearing assembly encircles an upper end portion of the strut member. The mounting bracket is configured to receive the bearing assembly with mounting bracket encircling the upper end portion of the strut member and further configured to attach to a portion of a vehicle body assembly of a vehicle. The noise isolating member is installed below the mounting bracket and along a surface of the bearing assembly reducing noises transmitted from the vehicle strut assembly to the portion of the vehicle body assembly.
