Hey!
I drive a 99 Wrangler Sport and was changing the oil in the rear Dana 35 when I decided to replace the pinion seal which had been leaking slightly. Upon removing the yoke, I noticed whoever had previously serviced the differential had coated a pretty large amount of RTV on the splines of the yoke and by extension the input shaft.

The Jeep had been driving fine, and I ended up putting this all back together as-is with a new seal and new pinion nut, but now I'm wondering if I should disassemble and replace the yoke itself. Any thoughts?

Thanks,
Pat

There is actually a rubber gasket you can get for that. The RTV is just a stop gap. I don't know that I've ever seen one leak that didn't have the gasket or RTV on it.. So I wouldn't worry about at this point. And if things are working OK now why take the chance pulling it back apart.

While more common on tcase versus pinion yokes, it is not a bad thing to put a light film of RTV on the splines but whoever did that went way way too far.

Really I only worry about tcase yokes but I can not stand those rubber washers and only use RTV now.

Every time I ever used one of those gaskets it was destroyed the next time I took the yoke off. Both t-case & diff.
