Shakes at 60 mph on expressway (2002 cadillic dts)


Recommended Posts

Had it in my Cadillac Don Gooley dealer of Detroit Mi, and they replaced a little ring that stopped my Check stabilaty lite from showing up, $400, plus car rental, but didn't stop the shake, I then took it to Pep Boys and they said my wheels needed balancce and rotated, had that done, still shack . Sat in garage the next night to try to figuge this out so I got mad and just floored the gas pedal and low and behold I got to about 40 rpms and the car shut downand turned itself off, I did it again same thing.

The next morning I called a local repair shop and told them what I found and they said I need a tune up, is that all possible and will that make it shake?

I don't know why Cadillac didn't catch this they claim they took it out on the e-way, but in there finding they say I need new tiers.

Can you help me with this.

Only 63000.00 on car

Thank you, DaddyMack Burns

Maybe you mean 4000 rpms?

Where are you from? Detroit?

Have you ever heard of Road Force balancing?

has Pep Boys ever heard of it?

You need at least one new tire.

Never underestimate the amount of a persons greed.

You floored your car while it was in neutral it hit 4000 rpm and it stalled?, or was it in gear? Please give detail

I think he hit the rev limiter.

Yes, that is what I was thinking also Logan.

But he said it stalled, what are the symptoms of hitting the rev limiter in Neutral, does it just cycle or bounce at limit or does it stall?

I think he simply hit the rev limiter. As for stalling...who knows...alot of these posts are hard to translate these days. I would suggest waiting to see if the followup post..if any..contains any more info.

As info I had a 2001 DTS with a vibration at 68 mph. The tires were Road Force Balanced and the wheels were checked. Finally I found a tech who really wanted to resolve the issue. He found a TSB that applied to the DTS only in 2001 with a specific break point in the VIN number. My car fell into the problem area. Their was a new style Lower Control Arms with some type of liquid filled bushing. They were installed at no charge under the GMPP and now it is a smooth as glass.

2 most common discussions on this site. type of oil and wheel shake. never heard of a liquid filled a-arm control arm. i believe the motor mounts are liquid filled. the rear knuckles have bushings and a 2nd layer of control arm bushings for 2 vibration damping points. the front end has a subframe with bushings and the suspension has bushings. lots of wiggle room i guess. am interested in this high tech a-arm for front end. wonder if it would fit on a seville?

The bulletin from Alldata is 00-03-10-007F and is dated February 05,2004.

Lists a number of GM vehicles BUT Cadillac are Seville 1998-2004 (SLS,STS)

2000-2004 Deville (DTS only)

Vehicles built prior to these VIN bread points.

SLS STS 3U24763

Deville (DTS only)3U247644

TSB reads "A newly developed Hydro-bushing lower control arm with improved dampining characteristics has been released.The new lower control arm may provide an incremental improvement to the vehicle "

Their is a whole list of procedures and forms the tech must fill out before it is covered under warranty. As I previous posted my 2001 DTS fell in the VIN bracket and was covered under GMPP.

Sorry if I mislead by saying Liquid Filled...Hydro Bushing is what the TSB reads
