The mobile stand is generally L-shaped in side elevation, having a horizontally extending base and an upright mast adjacent the rear of the base. The base is somewhat H-shaped in top plan, having a pair of widespread, parallel, horizontal legs that extend slightly rearwardly beyond the mast, and a crossbar that rigidly interconnects the legs adjacent their rear ends. The mast is fixed to the crossbar midway between the two legs. Four rubber stabilizer feet project downwardly from the base at its four corners to space the base a short distance above the floor. Transport wheels at the rear ends of the legs project downwardly from the base but do not engage the floor when all four of the feet are touching the floor, thus rendering the wheels ineffective at such time. When the stand is tilted back about the rear set of feet, the wheels are brought down into supporting engagement with the floor, such that further tilting back of the stand results in completely raising the feet off the floor and placing the entire load on the transport wheels so as to adapt the stand for transport to a new location.

Mobile stand for strut spring compressor

A hub puller device to simplify the removal of the hub from the wheel bearing on front wheel drive cars when maintenance is required. In the preferred embodiment, the device includes a U-shaped frame, a forcing screw, traveling nut and a pushing piece. A maintenance technician installs the forcing screw to extend through the open cylindrical section of the hub and mounts the pushing piece and the traveling nut on the forcing screw adjacent the cylindrical section. Next, the technician installs the frame to wrap around the spindle housing such that one member abuts the front surface of the spindle housing. The other frame member braces the receiving end of the forcing screw and prevents linear movement of the forcing screw. With the setup completed, the maintenance technician rotates the forcing screw and prevents rotation of the traveling nut. The rotational motion of the forcing screw is translated to linear movement of the traveling nut, which pushes against the pushing piece to eject the cylindrical portion of the hub from the wheel bearing.

Hub puller for front wheel drive vehicles

A strut spring compressor (20) having a support frame (22), a plurality of pivot arms (24, 26, 28, 30), a plurality of spring clamps (32, 34, 36, 38), and an actuating mechanism (40) is utilized to compress and expand a spring (42) of a strut assembly (44) whereby maintenance can be performed on the strut assembly (44). Each of the pivot arms (24-30) is pivotally attached to the support frame (22) by ball joints (74) which permit the arms (24-30) to pivot independently and three-dimensionally to compensate for a variety of spring sizes, and the spring clamps (32-38) are pivotally attached to the arms (24-30) to compensate for a variety of spring pitches. The actuating mechanism (40) includes a forcing screw (116) pivotally joined to a top trunnion assembly (118) and threadably engaging a middle trunnion assembly (120) and a bottom trunnion assembly (122). The forcing screw (116) includes a middle threaded portion (136) threadably engaging the middle trunnion assembly (120) and a lower threaded portion (138) threadably engaging the bottom trunnion assembly (122). The lower thread pitch is twice the middle thread pitch, so that the arms maintain substantially the same magnitude of angle with respect to the support frame (22).
