When do you need to replace pinion gear bearings?
Just torque the pinion nut to 150 foot pounds and see if that fixes it. It’s very common for the pinion nut to back off and most of the time torquing the nut is all you need to do. If you do this and you have a noise in the rear end then you may need to replace bearings.
What’s the best way to replace a pinion?
Put the new bearing over the pinion, the old one up side down on top, then you can use a pipe to press it down on a press. This way you will not damage the new bearing by pressing on the cage. Or you can buy the right tools, like I have….
What should I do if my pinion nut back off?
It’s very common for the pinion nut to back off and most of the time torquing the nut is all you need to do. If you do this and you have a noise in the rear end then you may need to replace bearings. When you replace the pinion bearings you must use a new crush spacer and reset the pinion bearing preload.
Can you change the bearings on a rear end?
Use a press! Imho (and just my opinion. )you should be able to simply swap the bearing using the same shim thickness. It would be different if using a different gear set. I used set-up bearings when I rebuilt my rearend and worked out great. The difference between bearings is negligible.
Why are my pinion bearings not working on my Silverado?
The oil seal behind the yolk wasn’t the right size, and neither one of the pinion bearings worked. They fit the pinion but did not fit the differential housing; the bearing and race OD were too small. Now on to the “How-To” with pictures: it will be as detailed as possible.
How to change the pinion on a Silverado Sierra?
Step 37: If the new bearings for the pinion are not OEM from the dealer, then you will have to knock the old races out using a punch and hammer and install the new ones. Step 38: Make sure proper shim is on the pinion then press on the new bearing. Put on the new crush sleeve and install the pinion into the diff housing.
Where does the pinion gear go on a rear differential?
The differential carrier holds the ring gear and connects the pinion gear to the rear axles. This unit shown is an open-type, no posi. When things get more serious, the rebuilds get more intense.
What causes a pinion bearing to howl when not accelerating?
Usually, a bad pinion bearing howls when you are not accelerating. This can also be a sign that the gears are worn or out of mesh, so any type of howling noise should be inspected immediately. This is a C-clip. Most rear ends use these to hold the axles in place. When these break, the entire axle and wheel assembly falls out.
What happens if you change the pinion nut?
By changing the bearings you might influence back lash and/or the pinion depth (pattern). You can’t check it with a sloppy pinion, but be sure to check both on the final assembly. Just torque the pinion nut to 150 foot pounds and see if that fixes it.

Why do I need to change the gears on my rearend?
If there is too much backlash, the ring gear needs to move closer to the pinion gear. If there is not enough, the ring gear needs to move away from the pinion gear. Just like the side bearings, the pinion bearings are adjusted by adding and removing shims of varying thickness.
Put the new bearing over the pinion, the old one up side down on top, then you can use a pipe to press it down on a press. This way you will not damage the new bearing by pressing on the cage. Or you can buy the right tools, like I have….
What should backlash be on front wheel bearing?
Compare it to loading or slightly tightening a front wheel bearing. Backlash is the crucial setting of the ring gear contact of the pinion gear. If there is too much backlash, the ring gear needs to move closer to the pinion gear.
