Rattle sound - 2004 Towncar

Postby thesavo - January 1st, 2017, 10:15 am

We have a 2004 Lincoln towncar with 143,500 miles. Recently a new sound started in the rear driver's side. It's loudest is at slow speed, it increases rhythmically with increased speed; until about 30-40 mph.

The sound is similar to steel balls rolling around, in the trunk. At around 50 mph, the sound seems to be diminished, but still noticeable.
The sound seems to have no effect on ride quality or handling. I'm headed to a friend's house to jack it and look under the back end. Is there any place to start?

Start with exhaust brackets and the rubber rings that hold it to the brackets. Get under and kick the exhaust in different spots and listen for a tiny noise.
I would guess a mounting issue but don't rule out a loose/ broken away bit inside the muffler.
If kicking doesn't work while jacked up start it and try various revs holding it at certain revs with someone outside listening.
Let us know if you find it.

I checked the tail pipe and muffler. They were good and tight, from what I could tell

I only just read in another thread that someone had a bent exhaust bracket that allowed the exhaust to make noise. On first inspection it was all secure but the bent bracket let it hit going over a bump.
Good luck I hate those noises.
My wife would suggest turning up the radio
Or stay above 50

The mechanic just called in. He is saying at the moment, there is no indication of a faulty wheel bearing. The rear axle on the other hand, is leaking into the parking brake and onto the disc rotor.
He also said the front stabilizer bar links are shot and also need to be replaced. He said the whole job should be $500

They did check the axle vent and it is cleared out. The total was $635. They replaced the following:
front stabilizer bar links
Left rear wheel bearing
Left rear axel shaft
Wheel seal.
12 qts of 75-210 synthetic gear oil.
The problem is gone.

Good it is solved.
Now you can turn the radio down as you don't need to cover the noise.
