Hey clan - I've got an 06 - sierra denali - AWD etc. I noticed my rear output seal on the t-case is leaking. Oreilly's gave me this one. https://www.oreillyauto.com/detail/...-1500?q=transfer+case+output+shaft+seal&pos=8 Will this one work? I tried looking on their website and they have a few different options. I just want to make sure I have the right part before I tear it down. Or......go buy every option in hopes that ONE of them is correct. Any insight? Thanks fellas.
