Help with seriously leaky rockwell

[JJorgensen52]

I've been driving my truck on the highway a fair bit as of late, and aside from the fact that it vibrates a bit in the t-case (which I would expect from a gear driven case like the rockwell), when driven at speed (60 - 65mph) for any kind of time the case leaks gear oil. A considerable volume of gear oil.

That said,

1. What in particular should I be looking for in terms of leaks? It appears to be leaking both from the tranny - t-case adapter and the rear yoke retainer.

2. Are seals / gaskets still available to an extent that I can actually get this thing to stop leaking? I've been super happy with it and would rather not change it out.

Sounds like you should be able to catch both of these leaks. Neither seal is too bad to address. You'll have to drop your driveline and split the case off the adapter, but it might be worth it if it saves you adding 90 weight often. The rear yoke seal might be the place to start since all you would need to do is drop the shaft and pull the yoke. You may have a groove in the yoke that is causing some of that leak. A new one or a sleeve on the yoke with a new seal works wonders. I agree with Vectorit, nothing hums quite like a Rockwell! Sharpie

sounds like you need some new seals. they should slow down the leaks, but won't stop them.
