Bearings and Covers that came with my car

When I bought the car all of these were in the glovebox. No idea what they’re for. Will I need them? Common fault? Anybody want them? What are they worth?

Hey Joe, they are rear wheel bearing kits. Looks like you have a pair. Still available at Mitsi main dealer for about £100 a side

Oh how interesting. Thanks Paul!

Hi Joe.
Are you looking to sell the bearings and covers?
Would be interested if you are.

Hi Paul,

Sorry but I think I’m going to hang on to these for the time being just in case I need them.
