Uber, I would make a suggestion for you to visit a good truck parts supplier - like Greggs Fort Garry. There are some great quality seal companies building top-notch seals for the truck industry - the truck parts suppliers are much more critical about quality than typical auto parts stores. The two manufacturers that come to mind are CR & Stemco. I'm sure they have automotive seals as well as all the truck & trailer seals. A good parts house the like the above two will know who makes the best seals, & they probably carry them.
