Great Scott!
Seriously, many thanks to yourself and Rick. I was going to use the same method but with glue. Loosening the plastic guide and then re-tightening it after placing the felt underneath is PERFECT.
Much appreciated for sure!

 

Excellent. Glad one more person is saved from losing their mind to that squeak!

Best,

 

Rick saving the day again!

I tried it today and no more squeak! It's so much better without the annoying sound on my ears.

 

can somebody post some pics. if i understand correctly part of the felt is visible. my seats are red and color match will be difficult.

 

I applied Shin-Etsu grease on the seat and it helped for a week now.

 

I used a small felt sticky thing that goes on the bottom of chair legs to keep them scratching up the floor. Just colored it black with a sharpie and stuck it where the seat belt rubs, partially under the plastic guide. Problem solved for over 2 years now.

 

I use black seatbelt/shoulder pads for both of my seats. I keep them up where the belt meats the seat and don't have noise issues. Occasionally a passenger doesn't put it up there, but that's a quick fix.

 

A piece of self stick velcro (the soft side) works great. I stuck one on each side years ago and it solved the problem.

 

Adhesive felt (you can find it in craft stores) does the trick permanently. As mentioned, just unscrew the belt guide on the top of the seat, lay down felt between the seat and guide, and screw the guide back in through the felt. Bam!
