Is there an industry standard or specifications for ball joint grease? I was wondering what grease is the best to use in ball joints? I would like to think that there is scientific testing to back up these claims and not just opinions? Thanks and let me know.

Squirt new grease in, no muss, no fuss, 35 years and going strong.

If they start grinding I know the bearing is bad. I do not know where the grease goes, only that it goes.

So I have looked into this some since my original post. NLGI certification certifies grease to certain standards and testing. https://www.nlgi.org/certifications/product/ Apparently they are tested to ASTM D4950. NLGI-LA or NLGI-LB certified greases are greases that are certified for chassis com…

My boat trailer has drilled spindles, zerk is on the end of the spindle, grease goes to the center then lubes both inner and outer wheel bearings. “I do not know where the grease goes, only that it goes.” Trailer hubs get warm to hot on the road, then immersed in cool/cold water, water is drawn i…

I had Bearing Buddies on my box trailer. It never got dunked in water so 5 pumps of grease in each of the 4 wheels each year kept the bearings happy. I never had to replace one. I have a fixture with 2 cone shaped parts and a spindle that allowed me to drop tapered roller bearings in and pump greas…

[image] It_s-Me: Yep, bearing grease works just fine for lubing anything on the chassis But you don’t want to use chassis lube on bearings. Yeah, bearings live a hard life, lots of load at high rpms. Ball joints and tie rod ends? They live on Easy Street!

Probably not technically a ball joint since there’s no up and down motion, the only motion is steering. I’m surprised there are no grease fittings there on that old rig. I can’t remember if my old solid axle Jeep had zerks there or not. I do remember a lot of zerks…ujoints had zerks, 4wd lever, clut…

By 1980 Fords twin-I-beam axles used ball joints which had grease fittings. A needle grease gun adapter is available that pierces the rubber boots on sealed chassis components and properly using them can keep original sealed components lasting indefinitely.
