Has anyone ever used a small syringe to inject grease through a permenatly greased ball joint or tie-rod end. Seems like a very small hole might not hurt anything. I am not talking about one that fits a grease gun, I mean a needle type syringe.
it will work ,you may have to heat the grease to get it through the needle. or use a 18 gauge or larger one . the smaller the no. = a larger needle.
drill the back of the joint out and insert grease fitting ,look in the gallery at how we did my driveshaft to grease it
