    Grease gun recommendation

    I have never had much luck with grease guns. I have two, a pneumatic one from Sears and an older conventional hand pump style. Neither one seems to deliver the grease with any amount of pressure to force the grease into a joint. Even when operated in the open, the most I can seem to get is about a half inch long “worm” of grease then nothing. I have been using synthetic grease (Mobil) which has the added problem of leaking red liquid out of every orifice even when the gun is sitting idle. Is there a trick to using these things? Is synthetic grease a bad choice? Is there a particular gun that is less troublesome?

    Thanks for any advice or guidance.

    I have the same problems and would love a recommendation for a decent quality grease gun.

    McMaster Carr lists the maximum pressure of their grease guns so I purchased the highest rated one. It has lived up to its rating but how to keep it from mysteriously exuding grease or to always pump after sitting idle for months is a complete unknown.

    Heating the joint with a heat gun will sometimes release the old grease.

    I also found that using a chain saw grease gun found at Lowes is the only way I know of to grease the door hinges. Only $6.38. Its called an Oregon 1.5 oz. Manual Pre-Loaded Chain Saw Grease Gun. Item # 91405 Model # 26365.

    Hi gpeirce

    We use a silver line pneumatic one and we use lithium grease. Works really well.

    I generally find, that it’s hard to get grease to come through on cars that haven’t received proper maintenance. Seized trunnions are usually the cause.
    Sometimes the only way is to rebuild suspension or at the very least strip and clean - by which point you may as well rebuild it with new seals.

    I have used a "grease fitting un-blocker" with some success. I hit it with a mallet and it unblocks almost everything. I like Paul's suggestion of using a heat gun; I will try that first next time.

    Re: Grease gun recommendation

    My issues have been with the gun rather than the fittings My frustration comes when the gun refuses to pump or leaks fluid out the bottom end. Since this post, I have done a little research on the topic. Look for an article in a future issue of the “Enthusiast”.
