How to fix a leaky windshield?

[OrlandoAlex]

My windshield seal has two or three leaks in it right now, which tend to appear only when driving in rain at highway speeds (55 mph+). I'd like to fix these, and it seems there might be a way to handle it by just removing the chrome trim pieces around the windshield. The leaks are in the upper driver's corner and upper and lower passenger's corners.
How common is this problem with windshields? Have any of you had to deal with it? What advice would you give on a good way to seal this up, perhaps even redoing the seal all the way around?
From reviewing the old posts it seems getting a real-deal replacement seal is pricey ($100 or so), and would require removing the windshield to do it. I'd rather not have to take such an extreme step if possible, since the price seems to be about $400 for new glass if I make a mistake.
Thanks for your time.

You can get a large tube of urethane sealant and go around the seal with it or you can take it to a glass shop and have them do it.

a little silicone caulc (black) will hold you over

I had the same problem in my J4000. What happens is that the w/s gasket dries and shrinks over time leading to the leaks especially in the corners. The above advice is good but to completely cure the problem, a new gasket should be installed.

You may be able to re-use your gasket. Pull your windshield out and remove the seal. Buy a tube of automotive windshield sealant (don't use regular silicone). Clean out the channels real good, and run a bead of sealant in the channel the glass sits into, and along the lip on the cab. I've had my windshield of my truck twice, each time using an old, used seal (both of 1971 vintage) and glass never leaked. I didn't feel like spending teh $65 for a new one.

"don't use regular silicone"-good advise. Over time it will rust out any metal pieces it is applied to. I had a perfectly almost rust free M38 one time. The window frame was ruined because someone used regular silicone to seal the window.

BJ's is the best place to get a new gasket, my vote is to order one, take it to a local glass shop and let them install if for you.
it is fairly easy to remove the glass yourself so you can save a little $$. but if you are afraid of cracking the glass let them do it.
urethane sealer will hold for awhile, but a new gasket will serve you alot better.
I think my local shop charged me $35-50 to install my glass so you should get it finished for less than 150. which is pretty cheap for a leak free cab

Thanks for all the advice guys. I'm supposed to be getting the Jeep back tomorrow (one day delay because the shop bought an a/c dryer that doesn't fit in the stock spot) and I'll take a look at those corners to get a sense of just how bad a situation I'm facing. I might pour a jug of water over it to take a look at exactly where the leaks are, then decide if a patch job will do it.
