squeeky a** door
 

My passenger door squeeks beyond belief whenever it is opened. I tried wd-40ing it but it didn't really help. Any tips?

pb blaster penetrating oil. Works wonders to get bolts loose and it penetrates any little cracks that wd40 doesnt, try it.

Try a lithium based lubricant spray.

I used to use Lithium white spray grease back in the '80's at Toyota, the 'officail" lube for window regulators. It only lasted a couple of years, and then would get stiff and tacky.

I would never use it again. I have great success with the spray silicone by Prestone for the hinges and places where you need it to flow into. Yellow can, wallyworld.

And, synthetic brake caliper grease for parts and places you can apply with your fingwer or a brush.

make sure to lubricate the door check strap...they tend to break or get loose from the mounting bolts....

AND...they can make an awful noise too.

Door Check Strap?

The thing that keeps your door from opening too far.

I think thats the culprit. Just use the same stuff you mentioned b4?
