What is the magical measurement? I recently had a rear end fixed and when it was returned I was told that I would need to find the correct shims. Is there a standard measurement? Am I correct in thinking that the only reason that comes into play is the proper pressure on the front bearing, I wouldn't think taking a few thousandths off the snout would have anything to do with the length of the torque tube overall.
Thanks for any help!

no one ever told me ...so I just measured how far the bearing went out of the housing,,then measured the resess in the torque tube...never thought there should be pressure on the bearing-the torque tube just restricts or contains the bearing from moving...there is no magic number till you measure...good luck

How much was machined off of the rear end face? Seems to me that is the size of the shim that you need....

That's the secret...he didn't tell me how much he took off...that's why I was asking. I didn't know if there was a standard measurement.
Thanks

There won't be a standard size since each machinist cuts off a different amount....

I usually measure the depth of the recess in the rear end housing prior to making the cut but I understand that you don't have that information. Where it becomes critical is in that you are looking to sandwich the bearing between the torque tube and the rear end housing. at the same time you have to insure that the bearing is not out of the rear end so far that the flat face of the rear end housing and torque tube still make contact (Reason for the shims) Install a torque tube and verify that the two surfaces are still allowed to make contact. Now if your case is a newer style, and has the steel case saver around the front lower shaft bearing, the shims will not fit over the metal bearing holder. You will need to trim the ID to fit. Also, shims only have one set of torque tube bolt holes in them, you will need to put a second set of holes in your shims if you still want access to the second set of bolt holes.

Thanks, that clears it up. I appreciate the input!
