A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) having a base portion (46) extending along an axis (A) between first and second twist beam ends (42, 44). The twist beam (24) includes a pair of side walls (48) extending downwardly from the base portion (46) and each disposed in spaced relationship with the trailing arms (22). At least one mounting bracket (54) extends from a first mounting bracket end (56) disposed in abutting relationship with a respective trailing arm (22) to a second mounting bracket end (58) disposed in overlaying relationship the side walls (48) of the twist beam (24) for allowing the mounting bracket to axially slip or slide along the side walls (48) of the twist beam (24) and provide for lateral or axial adjustment of the twist axle assembly (20) during the manufacturing process.

A motor vehicle series includes two different motor vehicle variants. The two motor vehicle variants include an identically designed chassis component fastening device, to which a stabilizer is fastened in the first motor vehicle variant and a motor-pump unit assembly with a motor-pump unit of a hydraulic damping system is fastened in the second motor vehicle variant. The motor-pump unit assembly includes a motor-pump unit for a hydraulic damping system. A holding tube is fastened to the motor-pump unit. A holding element, which is configured to be mounted on a chassis component fastening device of a motor vehicle, is fastened to the end of the holding tube facing away from the motor-pump unit.
