I've noticed my top start creaking pretty bad in the last few weeks. I have done the following:

1. Dielectric Grease on all weather-stripping
2. Tightened visors thinking I would get lucky
3. Tightened the rear latch which I think actually made it worse

How do I get rid of this creaking? I am pretty sure it is coming from the passenger side latch and I know there was a post on how to tighten it somewhere, but I can't find it with the search button.

Thanks in advance.

 

 

Have you put some grease (any kind) on the bearing surface of the latch itself? This worked for me.

 

I stopped my creak permittly by repostioning the front latches that are attached to the windshield. With the top off on the front latches at the top of the windshield, look dn from the top and pull back the plastic and you will see 2 screws (if memory services, 10mm wrench). Loosen them and push the latch mech. dn. just a tad and keep it level. Do both sides and tighten the screws back up. Put the top back on to make sure it's not sitting too low, If so them go back a raise them them a bit. Don't over tighten the rear latch. This is the only way to stop the creak! Grease this and grease that will not stop the creak, it will come back. Good luck

 

Here is the procedure for adjusting, good luck !

Wow,

This looks like it could do the trick. My driver side latch gives a nice "snap" into place when you close it, but the passenger does not. What is the windshield upper garnish panel and how do you remove that? I can just see myself breaking something plastic while tearing this apart

 

I use a 10mm craftsman ignition wrench for the front latches. It is a small open end wrench that is straight on one end and has the jaws at 90 degrees angle on the other. It is very thin and will access the bolts without removing the trim. If the bolts have been over tightened, then you may have to take it off.

 

Cool,

I had a 10mm that worked laying around the house. Seems to fix the problem as I could shake the top and hear it creak before and now I can't. Thanks for all the help.
