Slide not staying in tightly. What to check?

[rolling_rhoda]

We are looking at a two year old MH. The large kitchen slide rolls in tightly. However, after my 10 mile test drive it had jiggled out on one side on the bottom corner about an inch. I could stick my hand partway into the gap between the slide and the exterior side wall. What is causing this do you think? The other side of the slide has automatic locks and stays tightly closed.

Current owner will fix before sale. Thanks for enlightening me.

A hydraulically-activated slide may have a dual acting cylinder like our main slide does. We had a similar slide problem when one of the high pressure hoses going to the cylinder from the pump developed a leak. It can be messy but it's not difficult to fix.

Check under the slide for a braking lever. It may have got bumped when the bin was loaded.

I only have experience with hydraulic slides and I have had the exact same problem in the past. First thing you will want to check are the solenoids. If they are ok then most slides have 2 or 3 cylinders that extend and retract the slide along with an equalizer cylinder. After checking everything on my it ended up being the front cylinder that extends and retracts the slides. It was a blown interior seal. These can either be rebuilt or you will need to contact HWH to get a new one. Problem with mine is they did not stock the part and one had to be built which took o bit over a week.

If it is hydraulic (HWH systems) it may be a weak or failing solenoid. If I remember correctly, the 'extend' solenoid keeps the slide in.

If it is electric it may be the locking device has failed. That happened to us.

Do you know if it is driven by hydraulic or electric motor?
