Recently I noticed my car vibrates to left and right when I hit the pedal and the speed is around 40mph and above. The car runs smooth if I maintain the speed. The car has 176K and running quite good and I am about to have the timing belt service. I am just curious what could cause this: timing belt? fuel filter? thanks Tran Update: fixed typo Mph. the car is 2001 acura TL so it has front wheel drive. ---

If front wheel drive, get two new axles. ---

Check you motor mounts ---

I agree with insightful. The reported symptoms are consistent with worn-out CV joints (probably the inner ones), and replacing both front drive axles is what is probably necessary–if this mystery vehicle has FWD. ---

40MPS — All vehicles will vibrate at 40 miles per second – Sorry, I could not stop myself from this bit of nonsense. ---

Another agree for drive shafts. ---

I am very sure the engine mount is good because i ramped up the RPM while in park and observe the engine with hood open. If the the worn-out CV jonts cause the vibration then should they also cause vibration when I hit the brake? thanks Tran. ---

No - because braking is applied to the suspension - not the drive train. ---

…but we would still like the OP to clear up the mystery regarding exactly what type (make, model, model year) vehicle he is talking about. ---

OP edited original post with more information. But I think they should just have a good mechanic look at the car soon. ---

**^** Okay, now that we know the OP is driving a 13 year old FWD vehicle, I feel very comfortable saying that he needs to replace both drive axles. ---

does this problem need to be addressed immediately? or I can wait for a couple 1-2 months when I have the timing belt service? I will report back the findings from the mechanic Thx. ---

Hello guys, I brought my car to a local shop and the mechanic also said the CV joints. He quoted me $350(includes labor) using after market parts and $700 using Honda parts. The car has $180K so should I use original parts? thx. ---

You could try aftermarket, but if your going to keep it I would do oem. ---

@ctransj‌ Do not use chinese new parts . . . low quality, and they won’t last
