Rear Axle Nut Torque Spec & Strut Shims Questions

First question is a simple one.. I had to replace the left rear knuckle on a collision project. Naturally, I had to remove the axle nut. Just want to confirm that 275 Nm is the correct torque spec for the axle nut.

Additionally, the attachment point of the replacement knuckle for the strut is just a little narrower than the original. There are shims for the strut. I did note the original orientation of the shims. But, because of the narrower knuckle opening, I am not able to duplicate the original shim arrangement.

Certain that someone has BTDT before and grateful for any recommendations that anyone may be willing to pass along. I would be equally grateful for any tips with regard to placing the shims as well, as it's a royal PITA.

The shims are part # 47 of the attached diagram. There are three different shim types, though only two different shims were used in this application. Four skinny shims and two fat ones.

In this case, I had four slim spacers and two larger ones.

On other applications, is the usual arrangement just one large spacer on each side?

 

Upon further review of the situation, I am thinking the four extra spacers were put there to compensate for previous damage. Clearly there is no need for them with the replacement knuckle.

Further, when you look the spacers up by part number, it is indicated that a quantity of eight are needed. I assume this to mean eight spacers per car rather than per knuckle.

Things are starting to make sense... I think.

 

Here's a picture of the four extra spacers, plus one of the two wide ones.

Hmmm... These are the parts that were there from before.

For sake of comparison, I went around to the other side of the car for an inspection.

Didn't expect to see this...

I don't see how they ever fit the intended spacers in there the way it was, or why..

No doubt the other four are caliper shims. You have a sharp eye. I looked at the caliper hardware, and these are a perfect match to those shim sets.

 

Well, I was able to get it situated.. as originally intended.. on the side that I am working on. I still need to need to go around to the other side and correct the washer that had slipped on that side. Thank you for your responses.

It's a safe conclusion that someone had been in there before. Evidently, on both sides. Anyone need spare caliper shims?
