I think it will be tough to find a shop to re seal your rack. #1 they don't have the equipment and #2 more profit to just change it out. Gotta be careful @ the stealership as they like to up sale those free oil changes. The Lucas steering additive works great, just don't ad the whole bottle as it is thick and can cause stiff steering on cold days till the engine builds some heat. We use the Lucas at the shop quite a bit.
