As the title says, when I'm driving, a strong vibration is coming front the front wheels, specially from the left, it get worse driving uphill, but when I push the gas the entire car vibrates, the tires are relatively new, I replaced the outer tie rods (with oem) thinking that might be the problem, but the problem persist, what could it be?, CV joints? inner tie rod? the car has a new alignment and outer tie rods.

Are they good vibrations Laughing
But seriously, Get a good tire balance, possible broken belt in tire.
Do you remember anything that may be attributed to this?, if not, probably threw a weight.
Must of been a big weight if its that bad. Cool

The balance is O.K. as an adittional information if the car is cruising there is no vibration, but once I step on the gas at about 2500-3000 rpm's the vibration is huge, once the car is cruising again the vibration is gone.

The transmission shifts smooth and the Dexron is red and clean.

I was thinking it might be a bad CV or a bad dogbone mount.

check your mounts first can be done by trying to power brake with the hood up the motor should move but you will notice if it moves too much.

If the problem is happening under acceleration I would lean on it being the CV joints. That is the link between the Engine and the steering knuckle. It does not do it while coasting regardless of speed? Only whne throttle is applied mostly above 35MPH is were I suspect you are seeing the issue. It has to be the CV joints. The vibration is the initial stages of the joint catching on it self internally and releasing causeign the out of balance rotation of the shaft.

Bad Motor mounts would be felt as a heavy POP as you initially take off or as you come to a stop. The pop is the mount hitting the limit of the built in limiter in most mounts, or the engine is contacting something else and will show evidence to such.

This is exactly my problem, if the car is coasting there's no vibration at all, regardless of speed, but as soon as I touch the gas, it vibrates, sometimes at any speed above 20MPH.
As some extra info, the problem is with the 01 with 57K miles

Year of the vehicle is not important. What is important is to get to the one thing that is the link. That link being the CV shafts in this case. I will assure you swap both shafts get a good alignment done and that problem will be fixed. Shafts are not that exspensive should run you about 150 or so for the pair and can be swapped in about an hour for the pair if you know what you are doing.

Hey, aspevecek explain please, If it is as you say the cv joints/ axles, why does it not vibrate when coasting?
That's why I asked if it was a misfire. Cool

The lack of vibration from the cv shafts while costing is based on them not being torqued to say from being driven by the trans mission they are sorta in a free wheel state while costing. If you are coasting at say 65 MPH and hit the throttle you will instantly feel the vibration as the cv joint on the shaft tries to rotate and hitches on itself as it has torque applied. the vibration is the shaft catchign and releasing on itself at the inner (transmission side joint. Beacause the joint doe snot operate at the extreme angles then outer joint (wheel side) it will most like not give the famous popping sound as you take off or turn.

OK. I asked, you answered. I don't quite buy it yet. If new axels/joints cure the problem.
I conceed. Also hope it does fix the problem to be done with it and have a nice riding car on the road again. Good luck. Cool
