I have already read this post and it's not helping me. I have a 2015 RAM 1500 and both driver-side doors squeak badly when opening/closing. I have already tried the following:
- Sewing machine oil (easy and gentle, little mess)
- White lithium grease from a spray can
- Heavy black grease from a tube.
In all cases, the squeak goes away for about 2 days, then it comes right back with a vengeance. Part of me says I must not be hitting the actual squeaky parts, else the heavy grease would certainly end the squeak for months at least. But the other part of me says, if I'm not hitting the squeaky part, why would the squeak go away for about 2 days, no matter what lubricant I use?
Here is a photo of my hinge. You can see the gobs of grease all over it, and I tried to get it into every little angle and crevice.
What else can I try?
