dude i wish i knew...
Preload is the amount the pinion bearings are squeezed together by the pinion nut.
Which differential bearings? Pinion bearing? Carrier bearings? End axle bearings?
Depending on the vehicle, a diff bearing kit is a kit you can purchase that contains all the parts to freshen up a differential. This usually includes the pinion bearings and races, pinion bearing shims, pinion seal, pinion crush sleeve, pinion lock nut, carrier bearings and races, carrier bearing shims and a new gasket.
In a differential housing, the pinion gear is supported by bearings, typically tapered roller bearings or ball bearings, which allow for smooth rotation and alignment. These bearings are mounted on the differential case and provide stability while accommodating the axial and radial loads generated during operation. Additionally, the pinion gear is secured by a crush sleeve or spacer, which helps maintain proper bearing preload and alignment. This setup ensures efficient power transfer and longevity of the differential system.
trying to replace rear pinion bearings 1993 ford aerostar, 7.5 rear differential...slinger washer on drive shaft side is stuck, cant get pinion shaft out, all differential parts have been removed...any suggestions?
Could be the carrier bearings or pinion bearings in the differential(s). Mine was the wife and kids.
Probably have problems with the pinion bearings, carrier bearings and or ring and pinion gears inside the rear differential.
To change the pinion gear in a differential you must first open the differential, drain the gear oil and inspect the gears and bearings. Pinion gears and ring gears are usually done as a matched set so you should plan on replacing both. Remove the axle shafts and then mark the carrier bearing caps so they can be replaced in exactly the same location and direction that they came off. remove the caps and then pull the carrier out. Measure the pinion to axle centerline distance so that you can get the new pinion in the same spot. Remove the yoke retainer nut and the driveshaft yoke and then remove the pinion from the differential housing. You should be using new bearings and races so remove the old races from the differential housing and the old bearing from the Pinion gear. The shims from the old gear should be a good starting place to set up your new pinion depth. Test fit the new pinion to see if the pinion depth is right. Install pinion bearing races, bearings and new seal. Install new ring gear and set the gear lash You may have to shim the carrier or change the pinion depth to get the right gear lash. This process usually requires expert knowledge and specialized tools and you may want to consult a qualified mechanic to do the job. There are many more detailed descriptions on the net.
No. The pinion seal would be at the differential input.
I don't believe there is a specific torque specification! Once you install the crush sleeve and tighten the nut to the desired preload on your pinion bearings, your torque will be what it will be.
I think you mean ring and pinion. those two items make up the differential. They change the diection of rotary motion There is such thing as a Crown & Pinion... we are studying mechanisms in tech.
Remove driveshaft, remove pinion nut, remove rear cover, remove axles, remove differential. Push pinion out through housing.
