I have a 2001 blazer 4.3 lt 4wd with, apparently, a 236 transfer case. I was trying to replace a leaking seal, but non of my auto stores can find the right seal. it has several numbers (22452 and the letters UH098E). please help, I cant find the original manufacturer of this seal and no autopart store can help. Also, could it be possible that someone put a 235 transfer case when it was suppose to be a 233, like the autopart stores believe?

 

Try rockauto.com. I replaced all the output seals on my 233 and purchased everything through this site. Used ACdelco parts.
