Need tips on replacing bedroom slide lower wiper seal

Thanks for the tips!

I used a couple of small hydraulic jacks inside under the bedroom slider after opening the slider enough to access the seal from both outside and inside. It took a bit of tugging and pulling and pushing the seal back into place, but I was able to get it back in place, holding it there with some rubber gasket adhesive. I will replace completely after the trips are over for the year.
