1995 Chrysler New Yorker Shake/Shudder/Hard Shift

  • 6 CYL
  • FWD
  • 201,200 MILES
I have a 95 Chrysler New Yorker that I purchased the other day to replace my Jeep that died. (I miss it).

When I first purchased the vehicle, it had really bad vibration, road noise, and what sounds like a clunk when going over bumps.

After replacing all 4 tires, and ensuring the rims are true and free of cracks.I've eliminated most of the vibration and road noise.

However, it still has two things I need an opinion on. The first is the clunk I hear when going over bumps. When the tires were replaced, I noticed the front struts appeared to be bad. The boot was brittle and pushed up and I could see the piston of the strut. So I attribute the 'clunk' to possibly that. Thoughts?

The second, is a noticeable vibration when accelerating. It's sometimes accompanied by a hard downshift in the transmission. Mainly only happens at around 30-60mph. If I'm cruising on the highway at 70mph and go to accelerate to pass I don't notice it.

I went to three service centers and all of them told me since I don't know if/when the transmission was ever serviced, that it would do more harm to flush/fill it than it would to leave it alone. So I added a bottle of Slick 50 High Mileage Automatic Transmission Treatment and it helped just a bit. Not much, but I can notice a bit smoother shifting under load. The vibration and hard shift is still there though. Any thoughts?
Do you

The noise you described sounds like 90% of chrysler products. The cause is usually a bad strut plate or a stabilizer link. Check those. Also, if you replace the struts, replace the plates too.

As far as the vibration, have you checked to make sure the CV joints are good? Also, have you checked to make sure motor mounts and trans mounts are good?

Let me know.
