A wheel end assembly in a steering beam axle for use in a motor vehicle. The wheel end assembly comprises a tube yoke attached to an axle tube defining an axle centerline, a steering knuckle defining a steering knuckle centerline, a driving axle shaft rotatably disposed in the axle tube, a live spindle rotatably supported by the steering knuckle, a stub shaft extending through the live spindle and rotatably coupled thereto, and a universal joint connecting the driving axle shaft and the stub shaft. The steering knuckle is pivotally coupled to the tube yoke through a pair of vertically spaced swivel joints defining a steering axis. The wheel end assembly further includes a knuckle centering adjuster for adjusting the knuckle centerline by selectively moving said steering knuckle relative to said tube yoke along said steering axis in order to align the knuckle centerline to the axle centerline.

An antivibration sleeve according to claim 1, in which the first bearing zone of the first annular strength member co-operates with the second annular strength member to define a first liquid duct which extends in a circumferential direction about the central axis and which communicates firstly with the first hydraulic chamber and secondly with the second hydraulic chamber, said first liquid duct presenting a flow section that is at least three times greater than the flow section of said narrow passage, the elastomer body having a first axial rib which extends radially and parallel to the central axis from the first bearing zone of the first annular strength member to an outside edge in contact with the second annular strength member, said first axial rib thus closing the first liquid duct and presenting sufficient flexibility to enable a certain amount of decoupling between the inner strength members with respect to at least some radial vibrations at a frequency lying in the range 5 Hz to 50 Hz.3. An antivibration sleeve according to claim 2, in which the elastomer body further includes a bead which extends in the circumferential direction between the first bearing zone of the first annular strength member and the second annular strength member, said bead co-operating with the second annular strength member to define said narrow passage and also defining part of the first liquid duct.4. An antivibration sleeve according to claim 1, in which the second bearing zone of the first annular strength member co-operates with the second annular strength member to define a second circumferential liquid duct which communicates firstly with the first hydraulic chamber and secondly with the second hydraulic chamber, and the elastomer body includes a second axial rib which extends radially and parallel to the central axis from the second bearing zone of the first annular strength member to an outside edge in contact with the second annular strength member, the second axial rib closing the second liquid duct and presenting sufficient flexibility to enable a certain amount of decoupling between the inner strength member and the first and second annular strength members with respect to at least some radial vibrations at a frequency lying in the range 5 Hz to 50 Hz.5. An antivibration sleeve according to claim 1, in which the first annular strength member is constituted by a metal ring which presents two openings disposed respectively in register with the first and second hydraulic chambers, these two openings being separated from each other by said first and second bearing zones which are constituted by stamped portions of the metal ring.6. An antivibration sleeve according to claim 1, in which the first and second hydraulic chambers are occupied in parts by inserts adapted to limit radial movements between the inner strength member and the first and second annular strength members.7. An antivibration sleeve according to claim 6, in which the inner strength member has two bulges projecting outwards respectively into the first and second hydraulic chambers in register with the inserts disposed in said chambers.8. An antivibration sleeve comprising: a rigid inner strength member which extends longitudinally along a central axis; and at least a first rigid annular strength member which surrounds the inner strength member and the central axis, and at least one elastomer body connecting the inner strength member to the first annular strength member, said elastomer body including two diametrically opposite arms each extending along a first radial direction from the inner strength member to said first annular strength member, the elastomer body being shaped so that the antivibration sleeve presents relatively high elastic stiffness in said first radial direction and lower elastic stiffness in a second radial d
