Need some input; slide does not stay put

Haven't had an issue in awhile, but got one Im hoping someone has some insight on now.
My Lance 2008 981 has 1 slide, a full wall (dinette and fridge). After 100 miles of highway driving, with no real rough road, my slide backed itself out 2 inches . It retracted normaly after the trip, seated itself evenly with no weird sounds. This is the second time this happened, the first a few weeks ago. Same deal, noticed about the same slide movement at the end of the day. But earlier in the day the first time, I was on the beach in soft sand and there was a bunch of bouncing. I thought the slide box jumped some gear teeth,if it has them, and that was the cause. Today there was no out of the ordinary bouncing.
Some observations that might help. The rear portion was out 1/2 " further than the front. The bottom on both sides was kicked out a little further on the bottom than the top ( I think that's the way the box sits though)
Anyone have any thoughts on whats up?

I purchased a 981 Max new in 2005. The slide did that from day 1 and I didn't think much about it. When the TC was almost two years old (end of warrant period) I had it at Lance in Lancaster getting the auto transfer switch repaired and mentioned the slide problem to a technician there. He made a 30 second adjustment of some kind and the problem was fixed. It didn't occur again.

The moral to the story is maybe call Lance and ask them how to adjust it.
