Slides seam out of "square"

[RHS]

I have an '05 alfa syf29rlik 5th wheel. It has opposing slides both of which do not slide all the way in, they touch too hard on rear upper corners about half way in. They are not "square" with the opening when extended, close on upper rear & wide on upper front. It seams like they have "racked". I bought it a year ago at a good price from a used auto dealer. The price was good, needed several easy things done so I bought it without checking the slides because it did not have battery for slides. They rubbed hard going out but worked. After
living in it through the winter I needed to see if I could fix the problem.

I am stumped. I can usually fix most any thing. Does any one have any suggestions? thanks

I'm not sure what type of slide mechanism you have , all electric or electric /hydraulic. If you can track down the name on a drive motor , ( Lippert or Power Gear, or ? ) maybe we can track down info on adjustments.

My slide was out of adjustment by an inch vertically and horizontally, and even though I have read posts that don't recommend a DIY job, I got under there and just looked around and quickly figured out where adjustments could be made. I measured the difference from what I had to where I needed to be, and fixed the problem in just minutes on the first try.
I believe I have Lippert mechanisms.

Rich let us know your slide mechanism or RV year/make/model. Slides are usually adjustable.
