To lift your 2020 Grand Design Reflection 150 260RD 5th Wheel so it's 2" taller I recommend using the Correct Track Trailer Alignment and Lift Kit # RR23QX. This installs using the same frame mounting brackets that you already have - all you're doing is adding an extra piece of material make the mounting brackets "longer" for lack of a better term.
This is a very simple, yet effective, way to increase the height of your trailer to what you're needing! view full answer...
For your 031-032-02 bearing you can use the Replacement Trailer Hub Bearing # LM67048 and for your 031-033-02 bearing, you can use the Replacement Trailer Hub Bearing # L68149.
However for your grease seal, you are going to need to measure where you current seal rides with a set of calipers # PTW80157.
I've included a diagram for you to check out showing where to measure for the grease seal if you're unfamiliar. view full answer...
