Title: Np208 output seal
Post by: Halogin13 on September 10, 2017, 04:04:18 pm

 Hi all, just replaced my output seal, and the drips stopped for two days. And they're  back. I think my bushing is OK, because I have zero movement in it, but I did just buy a five dollar AutoZone seal. There doesn't seem to be a worn groove on my yoke, feels super smooth and shiny.. any opinions on this? With maybe a better quality seal fix the issue? I can see the drop forming at the rubber seal around the driveshaft

Sorry should have described better its from the front seal. The shop installed two new seals and it still leaks. They told me I needed a new yoke! Any recommendations? Picture is from another post but the same issue

When I grab the front shaft it does have some play in it. Both u joints are new. Would the CV joint be bad? Are they hard to replace thanks again.
