OptimisticPrime Posted October 2, 2013 Report Share Posted October 2, 2013 Hello everyone, I've read some info from this website a couple of times in the past, so I thought I would come here for help. I've been having trouble with my 2000 Cadillac DeVille DHS, that seems to occur mostly between 60 - 70 MPH. Particularly, the car seems to shake enough to make me uncomfortable. Particularly, the steering wheel, dash, and possibly the floorboards. I'm not sure what this is, so I thought I'd ask here. I've been thinking a possible problem with tie rods or bearings, but I have also heard of problems with motor mounts on this model year. I will probably do a power / brake check tomorrow and see if the engine moves much. Some additional info: I've owned the car for about a year, and it has about 80,000 miles on it. Any and all suggestions would be appreciated! - An estimated cost would also help. I'm a student, with a wee bit of experience in cars, but not a ton. Thanks Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted October 2, 2013 Report Share Posted October 2, 2013 Does it ONLY shake at 60-70 then stops above 70? Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...
KHE Posted October 2, 2013 Report Share Posted October 2, 2013 These cars are sensitive to tire road force - you might try having the tires road force balanced - not a traditional tire balance - use the Hunter website to locate a shop that has a Hunter road force balancer in your area. It is also possible one of the tie rod ends is worn out. There are no grease fittings on them and the grease dries out, then the joint wears out. I had a tie rod end go bad (which caused vibration) on my 2005 Deville at just under 61,000 miles. I thought that was a premature failure...

rockfangd Posted October 3, 2013 Report Share Posted October 3, 2013 I have to say I have the same problem on my 96 Deville. I have tried everything. I have heard it may be the bearing in the transmsiion housing for the cv joint. I sadly gave up on it a few years ago and have just dealt with it. But I also have 200k miles. How much many are on yours? GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
OptimisticPrime Posted October 3, 2013 Author Report Share Posted October 3, 2013 Thanks for the responses everyone Bruce, it happened at it's worst about 65 - 75 MPH. It seemed to settle down a little after that. Once I had time to really observe it, I noticed you could feel it in the throttle as well. KHE, you are absolutely right. I had a better look in the light and two tie rod ends were worn out. Since there's no grease fittings, it was metal on metal. I also had a wheel bearing that was worn out on the left front. I went ahead and took it to a shop and had all 4 tires replaced and balanced, as well. I haven't had much time to road test, but it rides quite a bit better. Unfortunately, though, I'm certain the shop scratched my car right above the wheel well. It's too deep for a simple fix, as well. rockfangd, I have almost 80,000 miles on mine.

rockfangd Posted October 5, 2013 Report Share Posted October 5, 2013 LOL I have 200k on mine so I suppose I would shake a little too. GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
stsbear Posted October 13, 2013 Report Share Posted October 13, 2013 I had the same exact issue with my 2003 STS. Cause was bad balancing of the tires. Was advised to get a Road Force Balance (only certain shops have that equipment) and an alignment, and the problem went away. Link to comment Share on other sites More sharing options...
