2014 Acura TSX, 4 Cylinder, Automatic Transmission. I believe all 2008-2012 Honda Accords and 2009-2014 Acura TSX with the 4 cylinder and automatic have same transmission. I’m trying to install the CV axle to transmission oil seal on the passenger side. I caved in and bought the special service tool from Honda, to get the seal driver. Much easier. I’ve taped it a few times to attempt to get it flush. The service data says it’s supposed to be flush. How crucial is it that it’s flush? I got about 75 % of it in flush, while the other 25 % I can feel a slight lip. I can continue to tap it in to try get even it out, but at the risk of it going in slightly crocked. It appears to be square in straight visibly at the moment. Should I continue to tap it in so that I cannot feel any lip? Essentially getting the seal in perfectly “flush” is very difficult if not near impossible, without having it go in slightly off center in one side and slightly crocked. The special service tool does not prevent you from tapping it in too far it seems. ---

Thanks. I’ll continue to tap it. This is what I got so far. ![IMG_20250411_180858349](https://global.discourse-cdn.com/cartalk/original/3X/4/f/4ffbd52644b9b719c967c66508827051e6db3f28.jpeg) ---

Should I have to smack it really really hard to get it to go in flush? ---

Yes. Using a dead blow hammer makes it easier. Tester ---

> [@pokemonyouandme123\_193319](#): > > I got about 75 % of it in flush, while the other 25 % I can feel a slight lip. Then it is not flush… Flush = 100% If someone starts hitting you over the head with a hammer, do you want them to stop 75% or 100%?? lol… > [@pokemonyouandme123\_193319](#): > > It appears to be square in straight visibly at the moment. Would you go for a ride into space if a part looked straight visibly?? Or would you rather have it 100% correct?? As Tester said, knock that seal 100% flush or it will leak prematurely… You can use a block of wood or something that is bigger than the hole and knock it in flat, the wood will keep you from going past flush and in to deep… ---

> [@davesmopar](#): > > Would you go for a ride into space if a part looked straight visibly?? Or would you rather have it 100% correct?? That depends who you are. NASA, DoD and Blue Origin are on the 100% bus. SpaceX is much more willing to take risks. Everyone is 100% for human space flight. It’s interesting when SpaceX works for the 100% crowd. I’m not suggesting that anyone is wrong, both sides have their advantages. SpaceX is willing to take more risk when launching their StarLink satellites because they own both. NASA and DoD are highly unlikely to assume higher risk becasue their payloads are extremely expensive and are often onesies. When there are problems with government payloads, Congress goes head hunting, and no program manager wants to end his career being pummeled (figuratively) by someone that sees political advantage as more important than anything else. ---

Thank you all. After some persuasion and persistence, I got it in completely flush.
