Pinion loose bearing
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 |

Re: Pinion loose bearing
Are you asking about the bearings on the differential?

Re: Pinion loose bearing
Any machine shop should be able to knurl the bearing surfaces on the carrier.

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?

Re: Pinion loose bearing
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 |
