Seized grease nipples
Hello all,
I seem to have the same problem on my 2020 3120RL. I have about 5 suspension grease nipples that do not take any grease. I like the idea of jacking up the frame to take pressure off the suspension, what I do not fully understand the comment "make sure the grease hole is at 30 or 90 degrees". Do I loosen the nut and try to turn the bushing? Seems like this is a common problem. Thanks in advance for any comments to help!
