My mechanic did not order the seals yet. All the bearings are standard bearings available anywhere except one. Its an skf bearing that is stamped st3562-2 which is a valid part number according to skf, however they do not offer an interchange. That leaves the only option of getting the bearing from volvo which no dealer parts person has been able to find a correct bearing. 3562 is the id and od, the -2 looks to be the difference in axial angle relashionship to standard bearings.
