Is that right, or will we still need to change the preload on the pinion once the new diff is in? I'll measure the torque on it at the moment and check it once the new diff is in to be sure, but in theory will we probably be ok with leaving the pinion alone?
All of the guides I can find seem to assume you are taking the pinion out as well, so I'm just trying to understand exactly which bits we need to do when we're only replacing the diff and not changing final drive. I'm assuming we will still need to get some different size shims for each side of the diff where the axles and bearings sit, but hoping to avoid doing anything with shims on the pinion end.

You won't need to touch anything on the pinion for any reason. You'll want to measure backlash and gear meshing prior to removing old diff then try to match when you put new diff in. This should only involve adjusting the side shims on the new diff to get proper preload and ideally match the backlash as closely as possible as already worn in gears.
