I see no place to lubricate the front jacks. Saying that, I met an older gentleman a while back who had devised a grease gun to lub the jacks. It was made out of PVC with a lub fitting on one end. It also was broken down into two section so one could slide it up the inside of the leg after removing the foot. This is all done with the RV attached to your truck. After removing the foot, run the jack as high as you can, then insert the pvc tube up the inside of the jack leg and over the screw shaft. Add the extra length and slide it up as far as you can. Then pump it a couple of times full of grease. Reverse the process when you are thru. I have done this a couple of times with our 2003 and then with our new 2005 Montanas. I guess it works as ours is smooth going up and down.
