Bedroom slideout stalls

[kj1949]

I have an older (1999) but awesome 2850. Wife & I love it. Everything works great except recently the bedroom slide drags and stalls about halfway coming in. It is hydraulic and the you can hear it running but the slideout stops moving. I can back it up a few inches and try again and after 3 or 4 attempts the slide comes all the way in. Once the bedroom slide is in, the living room slide then comes in with no problem. Any suggestions?

Just a guess, but I have read posts about the slide mechanisms attachment to the slide wall becoming unattracted. Lift the bed up and remove the plywood under it to expose the inner workings of the slide system. Look where it attaches to the head of the bed outside wall.
