Hi.
I kinda went crazy with the grease gun recently because I thought that you are supposed to grease the S Cam tubes until grease comes out on the slack adjuster side of the S Cam tube.
On 2 axles I had grease coming out on the S Cam side causing a huge problem. I cleaned it up and that was a huge pain.
Are there seals on the S Cam side of the tube? Did I just go crazy with the grease gun?
I was under the impression that the S Cam side is sealed and that's not supposed to happen?
Does it all need to be dismantled and new seals put in? I was trying to avoid pulling out the S Cam shafts but if it needs to be done I understand.
Thank you!

There usually is a lip seal there. When the cam and bushings are new, there's very minimal play. As the bushings and cams wear, there gets to be some slop in there and that can affect the seal's ability to work. Personally if the cam and bushings aren't excessively worn I wouldn't go to the trouble of replacing those inner seals. Most cases you'll have to pull the hubs to get the cam out. I'd just continue greasing them regularly and just watch the inner part of the cam and stop once grease appears.
With the u-joints I normally grease until I can hear them crackle, then slowly pump grease in until I can just see grease at each cap. That way I know each one has lubrication and there isn't a lot of grease getting slung around over everything.blairandgretchen, stillwurkin and Edjahman Thank this. -
