I ordered Maxima fork oil grade 15 off of Amazon and performed this procedure this morning per this bulletin: https://www.lci1.com/images/support/lipsheet/0295.pdf

One thing about this procedure that I did I'm not 100% on is that it says "Extend all hydraulic cylinders and jacks fully." This means that my front wheels were off the ground and I felt the coat slightly shift to one side.

Perhaps it's the spot, and I am being over sensitive to this. But I think the jacks are pointing a slightly different direction. I could have sworn they used to be straight up and down.

Today was a travel day so we moved from one destination to the next. Now that we are in our new destination, it seems now that the ram portion of the jacks are slightly pointed outwards. I verified that the frame welds were still good and it doesn't appear that the frame rails are bent. I'm really not sure where the extra play would have come from to make them appear as though perhaps the weight of the MH may moved the tips of the jacks outwards.

Am I just being crazy here? I'm just concern about bending my frame rails with the jacks.

Just figured out another possible cause for jack noise. Tire pressure. TP will vary with daily temp changes and sun shining directly on tire. TP changes could cause small changes in tire diameter - change chassis height and thus load on jacks. End result could be slight ram movement with more movement due to walking around in coach and changing weight distribution.

Good point. I've seen significant tire temperature changes just driving down the road when the sun is shining on one side. l

Follow up from my post. After two weeks I am happy to report that most of the creaking jack noise has gone away. I am still getting infrequent pops from my rear passenger jack. I'm going to continue to monitor. I'm optimistic it just needs to work through the system a bit more with a few more moves.
