Kingpins

Hey guys quick question I was having trouble getting the kingpin on the front of my 09 ws low max to take grease I used my air grease gun and it pushed grease out the bottom of the kingpin around a big c clip this was the other day. Today I put a little heat to it I did get the kingpin to take grease but now why is grease coming out where it is. Thanks trying not to replace kingpins till there wore out..

 

Tks for the reply I have jacked it up and checked for play there isn't any I think the grease did take the least resistance path I finally did get grease to the kingpin but the grease comes out by this c clip now I'm not sure what the c clips are for on some kingpins top and bottom there are 3 little bolts holding on a little cover I think in the middle of that is your grease fitting well the star or freightliner if you will use a c clip style. Why it's still pushing out there not sure. I'll keep digging lol thanks

 

Good morning thank you very much that's a perfect explanation and exactly what is happening.. I had trouble getting the kingpin to take grease so before I got the grease channel clear it spit out that seal... Can I remove the snap ring and replace the o ring without causing me big grief...

 

I want to thank you for your info you were bang on this truck has a Mercedes front axle in it and I'm lucky for 8.00 I bought a cover, seal and a new snap ring I think lol picking that up later today and going to change it so thanks again. Apparently there are some axles that western star, Freightliner use that when this happens you have to buy the kingpin kit to fix...
