You change the ring and pinion gears
how do you change front ring and pinion on 89 Toyota pickup
Possibly low of lube, or worn ring gear and pinion. Another possiblility is a defective wheel bearing or axle bearing.
Chances are real good you will take out your pinion bearing, pinion gear, carrier bearings, and ring gear in really short time.
could be ring and pinion or a bad u-joint or a wheel bearing
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.
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.
43 ring gear 14 pinion
count your teeth on your ring gear <big gear> and on you pinion <little gear> and the divide the ring gear teeth by the pinion
41 teeth on the ring gear, 10 on the pinion gear.
In order to replace the rear wheel bearing you will need to find the axle shaft bearings and remove them. They are located at the center of the housing where the ring and pinion gears and at the axle end near the wheel mounting position.
It is to transfer the power between the driveshaft and the wheels. The drive shaft drives the pinion, the pinion drives the ring gear, the ring gear drives the axle(s) and the axle(s) drives the wheels.
