Good catch on the manual and greasing the L bracket. I would bet money at some point i read the equalizer manual and it had me grease the L bracket. I did not want to, because i dont want to worry about rubbing against grease accidentally. But i like to follow instructions so i did.
Just checked the online manual again. Its telling me they do not recommend greasing the L bracket!! What in the heck? Either they changed the manual or the Youtube video they have told me to grease it. Wouldnt be the first time manuals contradict each other. In fact manuals often have blatant errors.
Ive driven my trailer both ways. There is zero chance i would drive it without grease on the L bracket ever again. There is too much friction in my opinion. Way too rough making turns. You can hear it load up and release rather violently. Ive had my L bracket supports move on me and i follow their torque specs. To me the L bracket supports are not thick enough metal. They want to bow out if you over tighten the bolts. Or you can torque them correctly and the darn bracket moves from the extreme friction.
Greasing the L bracket makes for a much more pleasant drive. I mostly need the weight distribution. Not the sway control. So having a small amount of grease is a benefit for me. But i also dont have to remove the bars. When i remove the hitch its all together in 1 piece and i dont touch the back 8 inches of spring bar.
Bummer for the OP because it sounds like he has to remove his bars and expose the greased end. I still think he/she should try leaving the bars attached but not under pressure. Are they somewhat stiff so they wont rotate forward enough to fall out? Leaving them hooked up for the terrain people are describing is a mistake i think.
