Weatherstripping for door - Tacoma World

Has anyone replaced their door weatherstripping? Does the old seal come off easily or (?). It it fairly easy to re-apply the seal to the appropriate location or should I chalk out the position of the old one before I remove?

Any tips or insights would be greatly appreciated.

Not talking about belt-line window trim - talking about the big flexible rubber door to cab seal.

I just replaced one of mine. There is a dimple or line on the weatherstrip. Make a mark with a pencil on the door sill, where the line is. Pull old strip off. Push new strip on, paying attention to the mark you made. It's super easy, takes just a few minutes.

The old just pulls off and the new goes back on. Nothing complicated about it. Note: the weatherstrip does have rubber caulking in it from Toyota. So when you pull the old off......don't be surprised to see some of the residual rubber caulking left on the truck body. The new (Toyota) weather strip will have the rubber caulking already in it....so no need to worry about putting some in it. You will need a rubber mallet or equivalent to tap the new back into place.

Look for a paint dot on the weatherstrip. That is supposed to be aligned to a certain point on the body when you install it. Typically, that point is near the upper, rear corner of the door opening. There is usually a notch or some unusual feature on the body at that "datum" location.
Depending on the model, the channel width of the weatherstrip may or may not be sized to match areas of the body where there are more than one body panel overlapping. In other words, the weatherstrip cross section may be wider where there are more than one body panels. That is why it is important to match the paint dot to the datum location on the body.
If there is no paint dot, you should be okay just starting anywhere. If you end up with extra, meaning a "hump" when you get back to the starting point, just smooth it out in both directions. It just means you pulled to hard when installing.

My weather stripping is torn in many places, its not leaking yet, but it doesn't seem like it will do its job much longer. The prices that Toyota charge for just one door is ridiculous, over $300. It seems like one of those things that isn't complicated, its just rubber gasket.

Do people usually use off the shelf parts to replace weather stripping? How simple of a job is it to replace it?

You can buy from a discount TOYOTA dealer and get a decent price or you can get aftermarket stuff that you will fight with and won't ever be perfect.

I replaced my driver's side door and was worth every cent.

Where did you see $300?
