I've done almost every trick I know, cant get grease in any of them. No rust, plugged grease, etc. Was told BB RE buses have bushings with a lateral groove in them and not one that goes around the whole bushing. I will end up pulling them out in the spring if I cant figure out how to get grease in them.
Any tricks to getting them out, aside from getting the weight and pressure off them?

| For stubborn ones I've had success by banging the heck out of the spring loop where the pin goes through with a sledge. Couple of good whacks, try to grease it again then couple more whacks, grease again. Works for me. |

| Ok and if I cant and I decide to pull them.....I assume I need a puller that I can screw into the zerk hole because you cant get at the back side of them. |

| If you haven't already tried it, take the weight off of them by jacking the body or chassis up, then try greasing them. Apply hammer and a little heat as needed... |

| Thats what I am planning to do once we get above zero by 50 degrees. :) I just managed to find a bottle jack that will lift the weight. |

| Ok, its official. I cannot get grease in the rear springs. I can get it in the hangers but not the loops. I have tried PB blaster, lifted the weight off, I even screwed a port-a-power hose in and tried that, nothing. Tried a little bit of heat and a hammer too. I cant get behind them to whack them out. I am at the end of my rope. Any more ideas? |

| If they have not had been taking grease for a long time the grease inside the pin itself is most likely dry and hard. Remove the zerk and dig it all out. Fill the hole with solvent ,insert zerk back in and build pressure back up with the grease gun. |

That was one of the first things I did. We managed to get the 2 offending front pins out yesterday. Blue Bird surely mis-thought this design. Come to find out it is a known flaw. I am told that you could try to grease them 2 weeks later and they would be plugged. I fabricated a puller and with a slight bit of heat on the holder, they pulled. Rear ones are going to be next to impossible I am thinking.
The pin has one hole in it and there was a very slight plug in it. There is no groove in the pins so there was nowhere for the plug to go, let alone the grease. We put a groove in the pins. |

| We used to have frequent problems getting spring pins to take grease, we switched to a calcium sulfonate grease and we rarely have the problem anymore. The product we use is Phillips 66/Conoco "Omniguard" |

| Good to know. This is my personal rig so I will grease the thing every other week for a bit.....just to be sure. Problem here is we are mainly gravel roads, which equates to dust. Dust and grease together make a lovely mess. |

We run a lot of gravel too. Since we switched to this Omniguard grease our spring pin and universal joint problems have reduced dramatically. |

Grease them more often!
Aside from that, gentle heat will soften that hardened grease..... don't exceed 400F or you will damage the spring leaf..... use an infrared device if you can. |
If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.

I bought it and tried to grease it when I found the problem. Like I said, its a Blue Bird flaw. You can grease them one week and the next week you cant get grease in. My goal is to pull all the pins and put grooves in them. Heat will soften the grease but it wont soften all the dust from the gravel roads. There is absolutely no place for it to go. The plug was so small, yet it couldnt move.
The only thing we heated was the hanger so we could pop the pins. I will bring my infrared next time to keep track of it.
Where do I get this Omniguard grease? We dont have stores around here. |

Its a Conoco/Phillps 66 product, we get it from a local fuel/lubricant distributor. |

| I use a Gromark (FS) product called Spectra Lube Green. It has served me well for over 17 years. I have very little problems with steering and u-joints. Carrier bearings on the other hand....... I wish they had grease fittings. |

Trick to greasing rear spring bushings?
