Rear hubs

Apologies if this has been previously answered, my use of the search feature has so far been unsuccessful.

Could anyone tell me if the rear hubs are common across all models, ie will 3.0 or 2.7 diesel ones fit my 2.5?

I can obtain good condition used hubs with good bearings at reasonable cost, but some info suggests the year is important, others imply hubs are interchangeable across most years and engine sizes.

Due to limited working area, I'm hoping to simply unbolt the old hub, and bolt on a replacement, thus sorting (for a while) the wheel bearing problem.

Many thanks for your help.
