Bad vibrations

N8Dogg98 · Jan 18, 2007

I have a vibration that increases with speed. This has been going on for about a month, and seems to get worse each day. Is it safe to assume that it is the u-joints? The vibration is present regardless of whether the clutch engaged or not. Also, what will it cost to change the u-joints if that is the problem?

I would suspect the tires myself.

I have two sets of wheels and the vibration is present with each set. The vibration intensifies when accelerating and decelerating, and is more subdued at constant speed. It sounds like it is coming from the driveline.

Is your car a 5 speed? My old clutch started to shake a bit when it was on it's way out. You can tell if a U-joint is bad if you get under there and give the driveshaft a little jiggle. When they are bad to the point to where they are causing vibrations or clunking, you can see the damage usually. Does the vibration change with RPM, or only speed?

N8Dogg98 · Jan 18, 2007

It is a 5 speed and the vibration is present at speed, although it seems worse with the car in gear (but that may be the o/r h pipe and cat back causing the extra racket). The other strange thing, is at low speed I hear a squeaking sound that intensifies with speed and goes away at around 10 MPH. It does not matter if the car is in gear or not, and the clutch position does not change the squeak.

Yep. Sounds like a u-joint then. Does this squeeking have a sound like it's occuring at a rate that is about 3-4 times faster than the wheels are turning? I don't know if that makes sense or not.

N8Dogg98 · Jan 18, 2007

Yeah the squeak is occuring at a quicker rate than the wheels are turning

'01 Steed · Jan 18, 2007

Yep...u-joint. There's a small chance that it's a pinion bearing, but I'd lean toward the u-joint.

Keep us posted.

Thanks, I really appreciate your input.

Is it a real deep tone? Sort of like a sub woofer with a steady sound coming from it? Happens at a certain RPM in all gears?

If so...U-joint.

....

Wouldn't that indicate a problem upstream of the final drive?

I think, and he'll correct me if I'm wrong, he's hearing more of a chirping sound.

N8Dogg98 · Jan 19, 2007

It is a real deep tone like you described along with some squeaking and chirping at low speed and under load at higher speed.

'01 Steed · Jan 19, 2007

Perhaps yours is a little further along than mine. ?

N8Dogg98 · Jan 22, 2007

It was a u-joint. The front one was horrible, but I had both replaced since the driveshaft was out. What a difference it made, she drives like new again! Thanks for all of your input, I appreciate it.

'01 Steed · Jan 22, 2007

Excellent!! Glad to see it's all set.

DTNODYA · Jan 22, 2007

Was it shaking/bouncing whatever at all speeds or did it go away at a certain speed? Reason I ask is because yesterday my car developed a shaking type feel on the highway but goes away at about 75mph. My shifter is bouncing/vibrating too .... I know it's not tires/alignment. What would you all guess, trans mounts, engine mounts, u joints?

Glad it worked out

My guess is tranny mount. Mine is doing the same exact thing but I have a new mount. I'm thinking it is screwed up too. Tranny mounts a cheap and easy to replace. I think I'm just going to pick up another.

Dont mean to hijack but i have the same sort of problem. Here goes:

There is a high piched squeak that only happens with the clutch engaged and when i am accelerating, i can just let the clutch out and it isnt there. Its coming from the front of the car i'm almost positive of that. I just had 4 new ties put on and no change. It also seems to not be so pronounced the longer i drive.

Thanks for any help.
