Hello, in shopping for tie rod ends for my 2003 Sequoia, I see two different part numbers for the left and two for the right, all with the same description, "tie rod end sub-assembly". (Although one out of the four total listings says, "tie rod end assembly #2", confusingly"). What might be the difference between, say 45046-09210 and 45046-39465? A search for either part shows current stock of either, with slightly different prices.
