Hi CFF,

Normally I would recommend taking it to the dealer, but since you are so far away. Are you a DYI Guy? Put the Ranger on rear jackstands and add a stickon weight to a tire on the rear. Have a person in the drivers seat plant their foot firmly on the brake. Have the person start the vehicle....still firmly on the brakes and increase the rpm until the squeak is heard. The tire imbalance will result in a vibration. Then without getting under the vehicle, crawl around the outside and see if you can directionally locate the squeak. It may locate the source. Otherwise....back to the dealer when you have the time...

Best,

Ok, I gotta ask. If your foot is on the brake, how is the out of balance tire turning? Or did I miss something?

Never mind about the brakes. I dropped the back seat and hear it much louder and seems to be something outside the cab but near the rear of the cab and front of the bed.
Have you checked the exhaust system? It pretty much just hangs there. One of the hangers may be squeaking. Quick check by just grabbing the tailpipe (after it has cooled) and give it a shake.

I tried shaking the exhaust and its made a noise, not 100% if it's the same noise though. I sprayed the hangers with grease anyways to see if the noise changed. No change at all.

Some exhaust systems have a "ball" type joint that allows for some misalignment. I've even seen these with springs on the bolts to allow the pipe to pivot but still hold the everything together. I haven't looked at my truck to see if any sort of joint is there, but you might check. It might need to be tighten slightly if it's present.

Hey folks, thanks for your input and apologies for taking so long to get back to this thread. Life got busy and I had to finish framing up a house and moving back home to Arizona, but i have an update. The sound got louder so i was looking over the truck and when I shook the exhaust I heard a new squeak. I shot it with some spray lube and the sound seems to have gotten quieter, now I can only really hear it with the rear windows down. Going to hit the hangers more thoroughly this weekend and see if it gets rid of the squeak, and I will keep you all updated.

Hi James,

Good Catch!.... Got ahead of my self and did not proof read...Sigh! Of course you cannot be on the brakes, but need someone poised in the cab to mash them if something goes terribly wrong as well as operating the throttle. You know...Once I thought I made a mistake, but I was wrong...... Embarrassing, but more importantly is to make the process correct,

Thanks again!

Actually, I knew what you were saying, just couldn't resist. All in good fun, hope you took it that way.

My bet is on the upper Shock Mount. Much more common is the front strut rubbers and bearings, but a squeaky rear shock is possible. I think it will be hard to make a big enough change to hear the squeak just by shaking the truck. Maybe a couple of people bouncing in the back?

I have been thinking it was the brakes causing the squeak since it seems to go away while any amount of braking is applied. There is a shiny area on the outside of the pad. Do you all think this is the culprit or normal wear? The outside pad on the driver side doesn’t seem to have this shiny area as pronounced.

Took it into the dealer and spoke with the brake expert who don't think it has anything to do with the brakes but they don't have any openings for the next few months to diagnose. I took this video that you can easily hear the squeak/chirp. Much easier to hear the noise with the rear seat back folded forward. Any ideas?

My 2019 Ranger has the exact same noise, have you had any luck ?
