Methods and apparatus for preloading a bearing are provided. The apparatus includes a rod having a first end and a second end adapted to be removably mounted to a shaft; a device for compressing a hub against the outer race of a bearing to provide the preload to the bearing; and a cylindrical frame positioned between the device for compressing the hub and the hub. These methods and apparatus include preload monitoring devices whereby the mechanic can accurately monitor and regulate the preload to a bearing or bearing assembly. Aspects of the invention may also be used to adjust the endplay on a bearing or a bearing assembly. In one aspect, the preload to the bearing is transmitted through a housing having a fluid whose pressure can be detected and monitored. An apparatus for precisely rotating a nut and a tool for precisely rotating a nut are also provided.

The invention claimed is: 1. An apparatus for providing a preload on a bearing, the bearing having an inner race mounted to a shaft and an outer race mounted in a hub, the apparatus comprising: a rod having a first end and a second end adapted to be removably mounted to the shaft; means for compres
The invention claimed is: 1. An apparatus for providing a preload on a bearing, the bearing having an inner race mounted to a shaft and an outer race mounted in a hub, the apparatus comprising: a rod having a first end and a second end adapted to be removably mounted to the shaft; means for compressing the hub against the outer race of the bearing to provide the preload to the bearing, the means for compressing mounted to the rod; and a cylindrical frame positioned between the means for compressing the hub and the hub, the cylindrical frame having a first end adapted to receive a load from the means of compressing the hub and a second end adapted to transmit the load to the hub. 2. The apparatus as recited in claim 1, wherein the second end of the cylindrical frame contacts the hub. 3. The apparatus as recited in claim 1, wherein the bearing comprises an inboard bearing, and wherein the hub includes an outboard bearing, spaced from the inboard bearing, the outboard bearing having an inner race mounted to the shaft and an outer race mounted in the hub, and wherein the second end of the cylindrical frame contacts the inner race of the outboard bearing. 4. The apparatus as recited in claim 1, wherein the apparatus further comprises means for maintaining the preload on the bearing. 5. The apparatus as recited in claim 4, wherein the means for maintaining the preload on the bearing comprises a nut threaded to the shaft. 6. The apparatus as recited in claim 5, wherein the bearing comprises an inboard bearing and wherein the hub includes an outboard bearing, spaced from the inboard bearing, the outboard bearing having an inner race mounted to the shaft and an outer race mounted in the hub, wherein the nut threaded to the shaft is adapted to bear against the inner race of the outboard bearing. 7. The apparatus as recited in claim 1, wherein the means for compressing the hub against the outer race of the bearing comprises an actuation nut threaded to the first end of the rod. 8. The apparatus as recited in claim 1, wherein the apparatus further comprises means for monitoring the preload on the bearing. 9. The apparatus as recited in claim 8, wherein the means for monitoring comprises at least one of a fluid-containing piston actuator, a compression spring, and an air spring. 10. The apparatus as recited in claim 9, wherein the means for monitoring the preload comprises a fluid-containing piston actuator having a piston housing mounted to the shaft and a piston adapted to transfer fluid pressure load to the bearing. 11. The apparatus as recited in claim 8, wherein the compression spring comprises at least one of a disc spring and a coil spring. 12. The apparatus as recited in claim 9, further comprising means for detecting the fluid pressure in the fluid-containing piston actuator. 13. The apparatus as recited in claim 1, wherein the means for compressing the hub against the outer race of the bearing comprises a nut threaded to the shaft and adapted to contact the cylindrical frame. 14. The apparatus as recited in claim 1, wherein the hub comprises a wheel hub. 15. The apparatus as recited in claim 14, wherein the wheel hub comprises a wheel hub of a tractor-trailer. 16. The apparatus as recited in claim 1, wherein the shaft comprises a wheel hub spindle. 17. An apparatus for providing a preload to an inboard bearing having an inner race mounted to a shaft and an outer race mounted in a hub, the hub having an outboard bearing having an inner race mounted to the shaft and an outer race mounted in the hub, the outboard bearing spaced from the inboard bearing, the apparatus comprising: a rod having a first end and a second end adapted to be removably mounted to the shaft; a fluid-containing cylinder mounted to the rod, the cylinder having a cylinder housing mounted to the rod and a piston; an actuating nut threaded to the rod and adapted to compress the cylinder housing toward the piston; and a cylindrical frame positioned between the piston and the hub having a first end adapted to receive a load from the piston and a second end adapted to transmit the load to the hub and compress the hub against the outer race of the inboard bearing to provide the preload to the inboard bearing. 18. The apparatus as recited in claim 17, wherein the apparatus further comprises means for monitoring the pressure of the fluid in the fluid-containing cylinder. 19. The apparatus as recited in claim 17, wherein the shaft comprises a spindle of a vehicle wheel assembly. 20. The apparatus as recited in claim 17, wherein the second end of the cylindrical frame contacts the hub. 21. The apparatus as recited in claim 17, wherein the second end of the cylindrical frame contacts the inner race of the outboard bearing. 22. The apparatus as recited in claim 17, wherein the apparatus further comprises an outboard bearing retaining nut adapted to engage a threaded end of the shaft and contact the inner race of the outboard bearing to retain the preload on the inboard bearing. 23. The apparatus as recited in claim 17, wherein the hub comprises a wheel hub. 24. The apparatus as recited in claim 23, wherein the wheel hub comprises a tractor-trailer wheel hub.
