Pinion loose bearing

[Kmoody]

Sorry if this has came up else where. I have looked! I have read all the paperwork and listened to all the utube videos. None that I have found really show how to handle when the inner pinion bearings spin on the shaft. I hope I am explaining this correctly. The bearings don't have to spin and yet the bearing will spin on the shaft. Metal on metal. Only thing I have heard is u have to Knurl the metal but how and what type person does it on this type of part?

Thank u

Are you asking about the bearings on the differential?

 

[Kmoody]

Yes

Sorry not pinion! The diff. I normally not the righting type I listen and read on here most all awnser are on this board somewhere already

Any machine shop should be able to knurl the bearing surfaces on the carrier.

If you are asking about the carrier see the link to Tom Endy's article.

I might have misread this but isn't the OP asking about the pinion beaering spinning on the shaft? If that is so, the carrier has nothing to do with it but I am confused too. The pinion bearing does not run on the shaft. You guys use different terminology from the rest of us but I'll try to explain.
The pinion has a machined cylindrical part at the front (of the car) end on which the inner track of the pinion bearing is pressed. Is it there that the slipping is happening?

If the bearings you speak of are the bearings on the carriers assembly (see following picture) you can knurl them by using a center punch and dimpling the surface where the bearing sits with an evenly dispersed pattern. The dimples will allow the bearing to grip when you press the new bearings on

If the bearing and surface is the pinion race to banjo surface itself then look for another housing, they're very common and will be the most economical option (see following picture)

If the final bearing surface is the pinion gear itself, then yes, a good machine shop can build up where the bearing sits and machine to fit, but care has to be taken so as to not take the heat treatment from the gear, differential gears are sold in sets so it may be worth looking into replacing the gear set

Hope this helps, sorry, the way the op states the question I'm not sure what bearings specifically are being asked about, happy New Years
