    I have a question about greasing front Springs.

    On the fld120, the rear hanger took grease but it only pushed out on the side near the fitting.

    Everything else pushed out on both sides.

    Is that acceptable for it only to come out on one side?

    Ideally it should purge between both shackles to ensure the pin/bush is thoroughly lubed. I wouldnt go changing it just yet. Run it some and retry it again.

    Could one jack up - to relieve tension in the suspension, so to speak - on that shackle, then grease?

    Yup.....sure could. Putting a bottle jack between the frame and spring might do the trick too. The grease will always take the path of least resistance and will likely continue to take the easy way out. I would just keep hitting it often to see if it straightens out.

    That's the ONLY way to grease Front Springs. In My Humble opinion...

    I did grease it with jack stands on the frame and the axle hanging free.

    I think @Goodysnap is correct.

    This truck sat for about five years before I put the engine in and I really went over the whole truck.

    So if I go down the road and let the spring do its work I think it will take the grease.

    While I still have it hanging I can jack the axle a little bit and see if that relieves it, and after I get the wheels back on it and the weight back down on it I'll try the bottle jack also.
     
    Cabinover101, SAR and Goodysnap Thank this.

    That is one way to do it, but my hangers are aluminum.

    And I think it will take grease once I go down the road with it, if not with the other ways described.

    Side note/Question ~ I want to buy the DeWalt battery operated Grease Gun. Does anyone have this or use this? I've read mostly good reviews on it.
