AWFUL shake when I hit 40mph

[Ceeker]

9/10 most likely center hanger bearing. If it is bad you may have to rebalance the drive shaft after putting a new one in. also check the guibo for pre-mature wear. also check the u-joints for looseness or seizing.

I'll throw in a motor mounts guess. Not the exact symptoms, but worth checking anyway.

Does it stop if you reach a higher speed? 50, 60? or does it just continue to get worse. I would guess bent wheel.

Vibrations at low speed are usually related to driveshaft.

- Check guibo at the tranny and center bearing.
- Verify that the U-joints on the driveshaft are not seized or loose.

- But also check the obvious: da wheels.

check your Guibo and your Center support bearing. i'm in the process of changing both of mine right now. Getting mad vibration in 2nd and 3rd gear around 50km/h.

i had the same problem turned out to be the center support it died on me and it was a pain in the ass to fix kind of :)

This should just happen under load, ie when accelerating. Or at least it will get worse when accelerating as far as I know.

Ill check my tires tomorrow. Ya it just randomly started right around the corner from home. Ya it doesnt do it until that speed. just cruising after 35+

[OOMPH!]

It could be something as simple as a piece of tread on your tire fell off, this happened to me and had the same symptons. Give your tires a quick check.

[Joe G]

did this just start all of the sudden?

[87e30]

So does it do it while accelerating? Or just cruising?

Sounds like just doing it more noticeably while cruising at higher speeds. I'd suspect unbalanced tires, bad ball joints. Probably will want to inspect both front control arms.

Maybe it's rear bushings though, I don't have experience with which ones will specifically cause shaking. I'd guess rear trailing arm bushings or subframe bushings could do it, though.

You'll need to get under the car and check out everything that 87e30 said.

[Dtmnuka]

smart ass

[txtorquemade]

You work for barley?

I can barely comprehend that.

[Dtmnuka]

the car is FINE until i get at 36-and up. then after Ive reached that speed itll do it harder and harder the faster I go.

Is that a cheap fix? by cheap I mean Im a college student working barely any hours a week haha
