Hi @rnj12 there is a fitting but a normal grease gun cannot reach it.
On the dark side there was a video of how to do this from a couple of years ago. You can by a 6" needle fitting to go on your grease gun that you can put against the zerk fitting and pump grease into it. I bought the needle fitting but it seems like a 3 handed job.
I only want to know how to get the whining sound out of the passengers seat
