Installing new slide gaskets

Just how difficult (or not) is it to remove and install new slide gaskets? It's time mine were replaced and prefer to do it myself, wanted the opinions and advice of those who may have does it themselves. Thanks in advance!

If you were talking about replacing them on a fiver I would say no problem. However, a buddy of mine has is headed to Red Bay to have his replaced on his bus this month. He is a retired mechanic and said it would be impossible for him to do himself, so they must not just slip out.

Red Bay, assume Tiffen. Mine is a Dutchstar, 03. Not sure the seals are the same.

Hi CSWolf,
If you are talking about the fuzzy material in the window slot, Newmar told me they are no longer available and they have no suggestions for a replacement.

You can order the correct slide seal from Newmar in the length you need. I replaced the front end on mine and joined it to the old seal at the top under the topper. I was advised by a repair shop to use crazy glue at the butt joint and it worked great. Doing just the front end of the slide I had easy access behind the drivers seat with the slide partially deployed. Doing the entire slide requires removing the topper to get access as it is done from the outside. The seal has metal fingers inside the rubber that press onto the lip of the slide opening and in my case also has a peel and stick lip on the outside wall. It's not that difficult to install but takes a fair bit of effort to press the new slide onto the fiberglass lip, i used a small pry bar and block of wood as backing against the fiber glass slide wall.

I would estimate replacing a full slide seal as a full day job for 2 people, almost impossible to do without help.
Good Luck

I just replaced my slide seals on all 4 of my slides. The seal on mine is 7/8" D glue on seal. Purchased from rvupgradestore.com Clean Seal 2828B-H2-50 EDPM Slide-Out D Seal - 7/8
A sharp chisel to shear and scrape off the old seal. I YouTube how to remove the toppers so I could access the top of the slide. Very simple process but need 2 people to do this. Easy DIY project, just take you time.

Stick with the Newmar members advice and get seals from Newmar or the link in QT's 1 & 2 slide section.

I noticed that the seal at the top of my door side kitchen slide had failed and allowed water to enter the seal, which in turn rusted out the "steel gripper" inside the gasket. It was not attached at all along the top by the time I noticed it. it was easy enough to remove. I ordered the gasket from Newmar (28' = $150). I started on the rear vertical and all went well until I got to the top. The clearance was only about 1/2-3/4" across the top and I just could not get my fingers into the opening well enough to apply the pressure necessary to push the grippers onto the frame. I used tools, called the dealer for advice (no tricks just fingers, pry bars and 4-5 hours of time was the advice) and spent about 4 total hours trying do just the top of the slide. I did about 1". In the end I closed up the slide and took it to my Newmar dealer who did the job. They had to repurchase a new gasket as mine was somehow damaged beyond use. If you have skinny rock climber fingers you may be able to do this yourself but I ultimately determined I could not. I begrudgingly spent the $800 for them to do the job.

I was up on the roof last year and noticed a strip of the grippers. all rusted, sitting on my slide. I took it to the dealer and my extended service plan covered the replacement.
